SU12598A1 - The method of obtaining water-insoluble azo dyes - Google Patents

Description

For the production of water-insoluble, E-resistant ovyl, ovat, and chlorine-valence by combining diazo compounds not containing sulfo or carboxyl groups with diacetodetectable precursor diamines of the SS type. CO, CH CO. NH. X. N3. Soo SS Soo SJ, (where X is a simple or substituted diphenyl residue in the core), a patent was granted for No. 10422,

In the proposed method, the preparation of water-insoluble azo dyes diazo compounds, not containing a sulfo or carboxyl group, is combined with di-acyl adethyl derivatives of diamines of the general formula

moreover, as a result of such a combination, colors that are resistant to soap and chlorine are found both on their own and on the block.

The same compounds are used as diazo compounds as in the main patent; as azokomponentov are useful, for example diatsilatsetilovye tioanilina derivatives, diaminodiphenyl ether, diaminodiphenylmethane, diaminobenzophenone, diaminoazobenzola, diamiioazoksibenzola, diaminodifenshmocheviny, diaminodiphenylamine, and on atsinobenzolfenilendiam

Example 1.-28.3 parts of 5-chloro-1. 2 Toluidine is diazotized in the usual way and the diazo solution is combined with an alkaline solution of 39 parts. Diacetoacetyl-4.4-diaminobenzfenone, to which the required amount of acetic acid is added, three. At the end of the compound, the dye is filtered off, washed thoroughly and rubbed into the crust. Mixed with commonly used substrates, it forms a durable yellow lacquer.

Example 2 .-- Formation of dyes on fiber. The well-boiled dried yarn is impregnated with a solution of 10 g of di-aceto-acetyl-4.4-diaminoazoxybepzol, 15 cubic meters. with. caustic soda solution

at 34 ° Wu and 20 cu. e. Alizarin oil in a liter, squeeze out thoroughly, without pre-drying, exhibit a diazo-solution neutralized with sodium acetate and containing 2.6 g of o-chloro-aniline in a liter. So get a bright, very strong yellow color with a reddish tinge.

New dyes can also be obtained by printing a diazo solution on a primed, product in the usual way.
