TITLE,. Preparation and stabilization of urea peroxide hydrate

PERIODICAL: Chemicky" prumysl, 1961, No.8, p. 417
TEXT,. This paper describes the preparation and stabilization
of the above compound on a laboratory scale. Finely-powdered urea
was added to an ice-cold solution of H202 and the solid reaction
product was isolated after two hours by suction. It was washed
with cold water and alcohol and finally dried at 30-350C. Using a
35% solution of H202 at OOC, the urea peroxide was obtained with 'a
yield of 635'. The use of more dilute solutions of H20~ and higher
reaction temperatures caused a kharp drop in yields. Stabilization
experiments were carried out by adding the stabilizing agents
(0-1 to 3%, as recommended in the patent literature) to the 8till
damp product and mixing it in with a glass rod. only then was the
stabilized product dried. Stability was determined at 450C by:
a) exposure to air, b) storage in a stoppered bottle, and
c) storage in a bottle with an inserted little water-container,

Best stabilizing effects were obtained with sodium sulfate; the
results were less favourable for boric acid or primary sodium
phosphate. Contrary to literature data, citric acid was found
ineffective. Decomposition of the urea peroxide is accelerated by
moisture and by products which catalyze the decomposition of H202
and which may be present in the raw materials. Urea peroxide
prepared from chemically pure raw materials showed an improved
stability.

ABSTRACT4 The authors investigated the influence exercised by ultra-
sonics on the conductivity of some semiconductors. Samples
of selenium, cadmium sulfide, galenite, cuprous oxide, tin
oxide, ruid germanium were irradiated with ultrasonics (fre-
quenoy 600,000 cycles and efficiency up to 10 W/cm2). In all
cases conductivity varied under the influence of ultrasonics.
However, an analysis of this phenomenon shows that ultrasonics
eXercises no specific effect upon conductivity , for the observ-
ed variation of conductivity is due to beating of the samples,
When ultrasonic irradiation was switched on, conductivity did
not change immediately but either increased or decreased
according to the sign of the thermal coefficient of the sample
under investigation. This variation depended on heating of the
sample during irradiation, in which case the law

irradiation the samDle cools down. The here discussed delibera-
tions are illustrated by a diagram. Irradiation of cuprous
oxide, tin oxide, cadmium sulfide, and germanium gave similar
results. For selenium slightly different results were obtained.
The authors investigated two groups of selenium samples: such
with positive and such with negative temperature coefficients.
The conductivity of the samples with positive and negative
temperature coefficients increased or decreased respectively
under irradiation. However, in the case of heating of selenium
by ultrasonics and cooling down after switching off of ultra-
sonic irradiation, a certain "hysteresis of conductivity"
occurs. This hysteresis is due to the instability of conduc-
tivity and may be ascribed to thermal influence. In connection
with what has been shown, ultrasonics probably exercises no
specific influence on luminescence. There are 11- figures and
6 references, 3 of which are Soviet.

16.5-10-4 absolute units at 6000 C. After repeated heating and cooling of
aluminum oxide, a A of 3.8-lo,*4 absolute units was meas!.~red at 10GOC,
which rose linearly with temperature to 5-71-10- 4 absolute units at '0600C
Investigations of asbestos wadding and asbestos powder showed that their
heat conduction coeffioients differ only slightly. For both types,valles
for A of 3-78*10-4 and 4.17-10- 4 absolute units at 100 0C were indicated
which rose to 4.53-10'-4 and 4.47*10- 4 absolute units at 660 OC.- The ,
specific gravity of Ceylon graphite was 0.82 g/cm3, the average grain
diameter 0.34 mm. The diagram of Fig. 1 shows that this graphite has a
X of about 9-1o-4 absolute units after preliminary thermal treatment at
about 750C, which rises at 729 0C -to about 15.5-10'" 4 absolute units.
Kudino graphites with a grain size of 0.01mm and 0.4 mm have nearly the
same specific gravity of about 0.8 9/cm3. While however, the fine-granu_
lar graphite has a nearly constant A of about I;_10-4 absolute units
(a poorly marked maximum at about 1500C), the K Gf the large-grained
type rises from about 13,10"4 absolute units at'100 C1 C to aboat IQ-10-4

from the diagram). Copper oxide (grain size 0-05 mm, specific gravity
3.28 g/cm3) shows, after preliminary thermal treatment, 21.6*'0"'4 absolute
units at 1000C. This value remained constant up to 300oC, and decreased
to 19.4-10-4 absolute units above this temperature (400-06OO'C). The in-
vestigation of powder mixtures shows that the X is additively formed
by the heat conduction coefficients of the components. There are I figure

TOPIC TAGS: plasma, plasma filament, dense plasma, plasma confinement, magnetic
plasma confinement, plasma diffusion,-ambipolar diffusion, helium plasma
ADST11ACT: Dense (1012 to 1014 cm-3) plasma filaments were formed in helium at pres-
sures from 0.1 to 0.01 mm Jig. The plasma filament carried a current wLth current
density up to 103 A/cm2 and was located in a longitudinal magnetic field of 7 We
or less. The gas prossuro and longitudinal magnetic field strength were varied, and
tthe radial density distribution in the plasma filament was measured. The densit
y
distributions were compared with calculations based on ambipolar diffusion theory.
The diffusion theory accounted adequately for the observations in magnetic fields
less than. 3 - k0o. The plasma f Ilamonts were formed in a tube 8 cm In d1waftr and 80 cm
long and contahtfng a hot tungsten cathode at one end and a cold anode at the -othor.At

',and a capacitor was discharged through the tube, thus producing a preliminary ioni-
,zation of the gas. A 5-millisec pulse was then applied to the magnat winding, pro-
iducing the longitudinal magnabic field. After' a delay of 1 to 1.5 millisec, giving
itho magnetic field time to reach a nearly constnnt value, a 3-millisec rectangular
]pulse was applied to the discharge tube, producing the plasma filament. The density
of the plasma was determined with a Langmuir probe. Mere is soma discussion of the
applicability of Bohin's formula to the present conditions, in which the ion Larmor
radius is less than the radius of'the probe, but it is concluded that relative den-
sities in different parts of the plasma should be given with adequate accu ' y. The'
electron temperature was diatermined from the intensity ratio of Ile 11 4686 to Ile
1 4713 J? lines; it was found to be 5 eV. Ilic highest plasma density observed was
5 x 1014 cm-3, and the ionization is said to have reached 100%. Via plasma density
decreased rapidly with increasing distance from the axis of the tube; the rate of
~decrcase was greater for stronger magnetic fields. In a 4.4 kOe field the density
fell to half its axial value at 8 mm from the axis, and to one-tenth its axial val-i
,ue at 23 mm. The steady-state relation between density and radius was calculated
from the theory of ambipolar diffusLongwith recombinatioA taken into account. Bes-~'
~sells equation of zero-order is derived for the square of the density (this equation
was also obtained by N.Rynn and N.D'Angello (Rev,Bc1,Instro3l,l326,l9GO)), and the

i solutions were fitted to the experimental curves. Good fits were obtained for radii
between I and 3 cm. This is not-astonishing, since there arc three dispo.,;nblc pura-
meters (two constants of integration and a parameter P that is theoretically proper-
,,tional to'tho magnetic field and to the square root of the recombination coeffici-
ent). The values of P that gave tho best fit were found to be in fact proportional
to the magnetic field for field strengths less than 3 We. 'Me value thus obtained
for the recombination coefficient is 3.9 x 10-11 cm3/sec; this value is of the same
order of magnitude as the values obtained by others (E.11innow and J.E.1firtsberg,
1Phys.Rev.125,795,1962; Yu.U.Alaskovskiy and V.L.Gzanovskiy,ZhETF 43,1253,10U), and
it is concluded that diffusion accounts for the behavior of the filaments iii fields
up to 3 k0c. In stronger fields, some dispersing mechanism in addition to diffusion
'must become important. Origeart,has: 8 formulas, 5 figures and 1 table.

blooU Y W disorders in paretic extremities following polionyelitis
were examined by oscillographic and plethysmor1raphic functional
tests. Both peripheralic and proximal parts of the blood bed are
influenced by the sympathetic tonus, The arterial system is un-
obstructed and the walls aro olastic. The angiopathy of the skin
found in somo patients is siviiiar to acrocynnosis, but differs from
it because it does not affect the distal parts, -nd has a focal and

TM: In this article is described a method of spectrum-scanning with a
stationary photomultiplier-slit in a spectroelectrophotometer designed on the
basis of the autocollimation spectrogr4ph with double diffraction. The image of
the Sun, formed by a vertical solar telescope, is constructed on the,input slit
of the spectrograph. The light-beam, after passing through the input slit and the
objective-collimator, falls upon the diffraction grating, By means of a supple-
mentary Plane mirror, the diffracted light-beans are again directed towards the
grating. The light-beams, diffracted for the second. time, pass through the ob-
jective-collimator, and the image of the spectrum is formed on the photomulti-
plier slit. The additional plane mirror is attached to a lever that can rotate

of the film in front of the osoillograph screen are performed by the same syn-
chronous motor CA-60 (SD-6o). Photocurrents of the multiplier are fed to a d.c.
amplifier before supplying to the electronic oscillograph. The speed of record-
ing is 40.A/sec- The diagrams of seven lines of MgI and Mg1I obtained for six
points on the solar disk are used for tiie measurement of equivalent widths. The

ABSTRACT: This research was necessitated by the construction of a
photoelectric solar spectrophotometer (P. P. Kozak, Astronom. zh.
v. 38, 549, 1961), in which the problem of ghosts was aggravated by
the inclusion of an additional mirror. The behavior of the Rowland
ghosts was investigated in the monochromator 6hamber*as the lines
were displaced continuously over the entire range, using a,mercury
light with in .tense lines capable of producing the ghosts. The inten-,'*

sity of the ghosts exhibited a periodicity with the maxima and mini-
ma occurring at fixed positions in the chamber. This periodicity
can be used in photoelectric spectrophotometry to eliminate the
ghosts by proper placement of the photomultiplier slot. This makes
it possible to use ghost-producing gratings in lieu-of first-class
gratings in some applications. A theoretical analysis of the re-
sults will be published separately. Orig. art. hast 3 figures and

Abstract : Investigations concerning the choice of aggregates of opti-
mm kinds and the study of their properties in concrete
were carried out with a iiiew to a more economical use of
cement at the preparation of concrete. The concrete
strength depends on the amount of contained sand, which de-
termines the necessary a un of cement and how much water
the mix requires. A decrease of the content of fine frac-
tions of sand increases the concrete strength. The

mineralogical structure and the grain shape of the agglome-
rate as well as its water permeability and strength are
Of great importance. In consequence of the great variety
of concrete compositions and of preparation methods, the
former curves of the grain composition of aggregates dis-
continued to answer their purpose. The Bolomey's formula
is valid only for concretes of the brand "400" and lower.
