ABSTRACT; The authors wanted to determine some physico-chemical quanti-
ties which characterize the state of the methyl ethers of
aminotriphenylcarbinols (formulae III and IV) and of the so-
-called amino bases of triphenylmethane dyes (V and VI) in.
which the central carbon atom is connected with the amino
group, dissolved in nitrobenzene. On that occasion the elec-
tric conductivity and the optical density of these solutions
were investigated. The hydrogen-iodide salts of the compounds
(VII) and (VIII) in nitrobenzene solutions are strong electro-
lytes. On dilution the electric conductivity changes propor-
tional with the dilution, the state of equilibrium immediate-

dilution of the solutions, where their stage of dissociation
was determined in different dilutions. The compounds of group
(VII) dissociate less intensively than those of group (VIII).
The equivalent conductivities of the cations of these groups
and the anions OH, OCH and NHC 6H5 in nitrobenzene solutions
were determined. The dissociation constants and the potential
isobars in nitrobenzene solutions were determined for the
hydrogen-iodide salts of groups (VII) and (VIII), of bis-
-(p-dimethylaminophenyl)-phenylca4binol, of the methyl ether
of bis-(p-dimethylaminophenyl)-phenylearbinol and of of--ani-
line-bis-(p-dimethylaminophenyl)-phenylmethane. There are 8
tables, and 12 references, 5 of which are Slavic.

ABSTRACT: In continuation of previous work (Ref 1) the author
investigated the dissociation of the aoridine derivatives
using the electrical conductivity method. The acridines
studied were iodo-9-phenyl-10-methylacridine (Formula I),
9-phenyl-10-methyl-9-oxy-,9,10-dihydroacridine (II), and
ihe methyl ether of the latter (III). It was found that
all these compounds dissociate in nitrobenzene solution,
and that this dissociation gives rise to the 9-phenyl-
-10-methylacridinium cation (I'), according to the mechanism
given in the paper. Table I shows that the electrical
conductivity of compound W does not change over a year's

time. The iodo-g-phenyl-10-methylacridinium behaves in
nitrobenzene as a strong electrolyte. The electrical
conductivity changes nearly in propDrtion to the dilutioll.
The dissociation occurs immedirtely. The dissociation of
the 9-phenyl-I 0-methyl-9-oxy- 9, 1 O-dihyd roac ri dine and its
methyl ether in nitrobenzene occurs gradually and increases
with the dilution. The highest electric equivalent
conductivity in nitrobenzene solution was determined for
iodo-g-phenyl-10-methylacridinium, 9-pl-,enyl-10-methyl-g-oxy.-
9p-dihydroacridine and its methyl ether, and the 9-phenyl-
-10-methylacridinium cation. The dissociation power for the
acridine derivatives in nitrobenzene was calculated at
different dilutions, and the dissociation constant of the
iodo-9-phenyl-10-methylacridinium was determined.
There are 2 tables and 4 references, 3 of which are Soviet.
