Abstract
Dichloro-3-iminophthalimidine is obtained by heating 3.4-dichlorophthalimide with urea in presence of ammonium vanadate. Nitro-iminophthalimidines are obtained by heating 4- or 3-nitro-phthalimide with urea in presence of ammonium vanadate. Methoxy-3-iminophthalimidine is obtained by reacting 4-methoxyphthalimide with ammonia to give 4-methoxyphthalimide, which is dehydrated with acetic anhydride to give 4-(or 5-) methoxy-2-cyano-benzamide which is isomerised to the iminophthalimidine by heating. Imino-thiophthalimidine is obtained by passing hydrogen sulphide into a cold suspension of phthalonitrile in aqueous alcoholic sodium hydrogen sulphide.ALSO:Dyes are made by heating iminophthalimidine, thiophthalimide, or iminothiophthalimidine or a nuclear substitution product thereof (e.g. a methoxy-, chloro- or nitro-substitution product-see Group IV (b)) with an aromatic hydrazine or with an aromatic primary amine which contains in its molecular structure in addition to the amino group, a second amino group, or a substituted amino or hydrazino group, or a condensed ring attached to the aromatic nucleus, or a pendant ring attached through a linking group to the aromatic nucleus. Amines or hydrazines specified are m-phenylene diamine, 4,41-diaminoazobenzene, 4,41-diaminostilbene, o-tolidine, 3,31-dichlorbenzidine, 5-chloro - a - naphthylamine, 2-aminoanthracene, 2 - aminoanthraquinone, 1,4 - diaminoanthra - quinone, 3-aminocarbazole, copper-tetra-aminophthalocyanine, 2,4 - dinitrophenylhydrazine. Solvents may be used, e.g. alcohol or acetic acid. The products colour paper and polyvinyl chloride and dye cellulose acetate and nylon. They may be sulphonated to give wool dyes. In examples, iminophthalimidine is reacted with (1) dehydrothio-p-toluidine; (2) p-aminoazobenzene; (3) o-dianisidine hydrochloride; (4) p-phenylenediamine; (5) 2-aminobenzthiazole; (6) phenylhydrazine hydrochloride. Also in examples: (7) dichloro-3-iminophthalimidine is reacted with benzidine; (8) nitro-iminophthalimidine is reacted with p-sulphophenylhydrazine or dehydrothio - p - toluidine; (9) methoxy-3-iminophthalimidine is reacted with o-dianisidine hydrochloride; (10) iminothiophalimidine is reacted with o-dianisidine hydrochloride; (11) thiophthalimide is reacted with phenylhydrazine.
