TITLE: The Properties of Dyes Soluble in Acetone
PERIODICAL: Khimicheskiye volokna, 1960, No- 41 PP- 31-39
TEXT: To a growing extent, dyes soluble in acetone are used for the dyeing
of acetate rayon. Theyrecently have been synthesized in the Derbenevskiy
khimicheskiy zavod (Derbenevskiy Chemical Plant). Here, hydrophobic dyes
with a Cr or Cc 1:2 complex and the series "Orazoll", "Telazoll", and
"Irgatset" were concerned. For the practical utilization of these dyes, theiz
solubility must be known. In the preceding studies made in the physico-
chemical laboratory of the authors, institute by means of an electron micro-
scope with a resolving power of 50 A, V. P. Kovaleva has found that the
solution of these dyes contains no visible particles. The authors discuss
the solubility of the dyes at 20 0C. The test portion of the dye (1-10 g,
in some cases up to 30 g) was dissolved a) in 50 ml of acetone; b) in a
50-m1 mixture consisting of 5% water and 95% acetone (the data obtained did
not differ from those of a))j c) in a 50-ml mixture consisting of 10%
ethanol and 90% methylene chloride. Solubility was determined gravimetrical-

ly as well as colorimetrically by means of an 4)3K-.4 (FEK-M) electrophoto-
colorimeter. 16 dyes were studied. Examples of the principal structure of
these dyes are given. They belong to the following groups: 1) hydrophobic
metal-containing monoazo dyes with Co or Cr 1:2 complex; 2) metal-contain-
ing monoazo dyes with Co or Cr 1:1 complex; 3) dyes for acetate rayon which
are dispersed or soluble in fat; 4) a phenyl phthalocyanine dye with four
heptyl sulfamide groups in the molecule. Fig. I shows the dissolution
kinetics of these dyes. In all dyes a dependence of the concentration of
their solution on the test portion was found. With a test portion of 30 9
in 50 ml of acetone, the dye soluble in acetone yellow F -19K (G-19K) at-
tains a solu)ilitY Of 436 g1l, For this reason, also the quantity of dye
which remained unsolved in different test portions was determined. The
proportion by weight between the dissolved and the undissolved portion
is proposed as a new characteristic value for the evaluation of dyes and
the elaboration of dyeing prescriptions, The solutions of dyes soluble in
acetone are polydisperse; a partial association occurs. The solubility
of hydrophobic metal-containing monoazo dyes with a 1:2 complex with a test
portion of 5 g in 50ml of acetone was on the average four times higher
than that of the known dispersed dyes with a 1:1 complex. Introducing
the rhodamine base into the dye structure loviers the 3olubility of the dye
