Abstract
Condensation products are prepared by heating in the liquid phase aromatic hydroxy or aromatic primary or secondary amino compounds, which contain in addition to the hydroxy or amino group at least one further such group or carboxylic group or an enolizable side chain, with polycarboxylic acids or their anhydrides formed by the addition of aliphatic a -b -unsaturated-a -b -polycarboxylic acids or their derivatives to natural or synthetic resins or oils of unsaturated character. Suitable reactants include hydroxy or amine compounds: 1.3-dihydroxybenzene, 1.3.5-trihydroxybenzene, dihydroxynaphthalenes, dihydroxydiphenyls, dihydroxydiphenylamines, 1-amino-3-hydroxybenzene, 1 - methylamino - 3 - hydroxybenzene, 2 - amino - 8 - hydroxynaphthalene, 6 - amino-2-hydroxynaphthalene-3-carboxylic acid, 1.3-and 1.4-diaminobenzene, diaminonaphthalenes, 4.41 - diaminodiphenyl, 4.41 - diaminodiphenylamine, 3.6-diaminocarbazole, 4-aminobenzoic acid, aminonaphthalene carboxylic acids, aminoazobenzene carboxylic acids, 4-aminobenzoylacetic acid arylides, monoacetyl compounds of diamines, esters of hydroxylamino compounds, nitrophenols or nitroamines (which may be converted into aminophenols or diamines after condensation) or bodies which contain further substituents such as halogen, alkyl or alkoxyl groups; polycarboxylic acids: maleic acid, maleic anhydride, aconitic acid aconitic anhydride; resins or oils: colophony, abietic acid esters, wood oil, täll oil, gum dammar, coumarone resin, or root resin. Reactive groups in the products may be further reacted such as, for example, by condensation with formaldehyde. The reaction products, which are soluble in aqueous alkali, may be used as intermediates in the preparation of dyestuffs, as medicaments, and as assistants for the textile industry. Products derived from coloured bodies, such as aminoazo compounds, may be used directly as dyestuffs and azo or triphenylmethane dyes derived from condensation products are oil-soluble. In examples: (1) the addition product of maleic anhydride and colophony or abietic acid is reacted in solution with 1.4-diaminobenzene, 1.3-diaminobenzene, 4.41-diaminodiphenyl, 3.6-diaminocarbazole, (the resulting amides in each case being reacted, if desired, with 2-hydroxynaphthalene-3-carboxylic acid or benzoyl acetic acid ethyl ester to yield dyestuff intermediates), 1.3-dihydroxybenzene, 2 - amino - 8 - hydroxynaphthalene, 2-amino - 7 - hydroxynaphthalene, 1 - amino - 5-hydroxynaphthalene, 4 - aminobenzoylacetic acid anilide or 4 - aminobenzoylacetic acid anilide - 41 - carboxylic acid; (3) the addition product of wood oil acid and maleic anhydride is reacted with 1.4-diaminobenzene and further with benzoyl acetic acid ethyl ester. Specification 355,281 is referred to.
