Title: Process for the manufacture of dyestuffs for esters of cellulose and products resulting therefrom
IPC: C09B29/08
Filed: 1936-02-12
Abstract: Azo dyes for cellulose esters are made by coupling the diazo compounds of aromatic amines containing no free COOH or SO3H groups with hydroxyalkyl derivatives of 3-hydroxy-diphenylamine of the formula <FORM:0454757/IV/1> in which R and R<1> may both represent hydroxyalkyl groups and the nuclei may be substituted, or in which R = hydrogen and R<1> = hydroxyethyl, dihydroxypropyl, chlorohydroxypropyl or alkoxyhydroxypropyl and the nuclei may carry alkyl or alkoxy residues.  In examples dyes from the following components are described: p-nitroaniline, o-chloro-p-nitroaniline, 2 : 4-dinitroaniline, 6-bromo-2 : 4-dinitroaniline, aminoazobenzene, p-nitroaniline --> 2 : 5-dimethoxyaniline, bromo-4 : 5-dinitro-o-anisidine (made by bromination of a finely divided aqueous suspension of 4 : 5-dinitro-2-aminoanisole), 2 : 6-dichloro-4-nitroaniline; 3-hydroxyethoxydiphenylamine, 4-ethoxy- or 4-methyl-3<1>-b -hydroxyethoxydiphenylamine, 3-methyl-6-methoxy-3<1>-b -hydroxyethoxydiphenylamine, N-b -hydroxyethyl-3-b -hydroxyethoxydiphenylamine and its 4<1>-methyl derivative, 4<1>-methyl-N-b -hydroxyethyl - 3 - g  - methoxy - b  - hydroxypropyloxydiphenylamine.  The coupling component may be dispersed in aqueous Brecolane NCK (a condensation product of naphthalene and butyl alcohol) with or without size or dissolved in chlorobenzene.  The dyestuff may be dispersed, e.g. with sulphite cellulose waste liquor.  Red, brown, Bordeaux and violet shades are obtained.  Hydroxyalkyl derivatives of 3-hydroxydiphenylamine of the above formula are made by treating 3-hydroxydiphenylamine or its substitution products or N-acyl derivatives thereof with ethylene oxide or epichlorhydrin.  In examples: N-acetyl-3-hydroxydiphenylamine is heated with ethylene oxide in chlorobenzene and the product hydrolyzed to form 3-hydroxyethoxy diphenylamine.  4-Methyl-3<1>-b -hydroxyethoxydiphenylamine is made by condensation of p-toluidine with resorcinol, N-acetylation, treatment with ethylene oxide and hydrolysis, the 4-ethoxy derivative similarly starting from p-phenetidine and resorcinol and the 3-methyl-6-methoxy derivative starting from p-cresidine and resorcinol.  N-b -hydroxyethyl 3-b -hydroxyethoxydiphenylamine is made by heating 3-hydroxydiphenylamine with ethylene oxide in chlorobenzene and the 4<1>-methyl derivative similarly. 4<1>-Methyl-N-b -hydroxyethyl - 3 - g  - methoxy - b  - hydroxypropyloxydiphenylamine is made by treating N-acetyl-3-hydroxy-4<1>-methyl diphenylamine with epichlorhydrin and reating the oily product of high halogen content with alkalies and methyl alcohol to remove the halogen and acetyl group and form 4<1>-methyl-3-g -methoxy-b -hydroxypropyloxydiphenylamine which is then treated with ethylene oxide in chlorobenzene.
