Abstract Continuing the ainilar study of dialkylsulfides (DAS)
containing the nlkvls 01-C4 with straight chains, brcmidos,
picrates and perchlorates of dialkyl-n-bro-nophenacylsulfo-
nia (1) from 17 DAS-s were obtained; they contain one or
two C3-C4 alkyls with forkad chains (with the exception
of tertiary butyl); their melting points, by which it is
recommended to idonti:-.y the corresponding DAS-s, were de-

tormined (malting points of perchl grates - from 69 to 170',
those of picrates - from 80 to 150 ). I is produced by the
interaction of the DAS with n-bromophonacylbromido, which
takes from 20 min. to 8 hours time; a DAS with forked
chains reacts more slowly than a DAS w1th straight cohin-,.
The picrates and porchlorates of higher DAS homologues are
produced from bromides without separating the latter from
the reaction mixture. It is rooommended for a more complato
identification of the DAS-s to use tho x-ray pictures of
powdered I perchlorstos and the eutectic temperatures of
their mixtures with some standard preparations,. The
malting points of bromides, perchloratus and picrates of I,
as well as x-ray picture characteristics and outectic tempo-
ratures of I perchloratos obtained from the above mentioned
DAS-s are presented. See repot XV in RZhKhim, 1958, 32229.

By ititefing the stationary phase (water, noruq., polar sol-
'vent, nimpolar solvent) or the polarity and conipti. of the
mobile phase, the migration of the stains in the chromato-
gram can be influenced, selected RI values can be obtained,
and in many cam it is also possible to secure a desired suc-
cession of the compds. on the chromatogmai. Since the

complicated and must be solved Individually for tacit cam.
Morcovcrx the soly. characteristics can be affected by using
reactive solvents; for instance the compds. can be con-
verted into water-sol. salts. Compr=tlons may arise be-
cause of the dissocn and hydrolysis of Ionizable compds.
