Abstract
1494161 Stabilized halogenotriazine dyestuff preparations BAYER AG 25 March 1976 [26 March 1975] 12062/76 Heading C4A A halogenotriazine reactive dyestuff, or dyestuff mixture of two or more halogenotriazine reactive dyestuffs, which contains a triazin-2-ylamino group which is substituted at the triazinyl ring by at least one halogen atom, is stabilized by adding a carboxylic acid buffer, which in aqueous solution maintains a pH value of 5À0 to 8À0, as a buffer, to the dyestuff or dyestuff mixture before or during the production thereof or, after reaction is complete, before, during or after isolation thereof from the reaction mixture. The carboxylic acid buffer is a mixture of a polybasic carboxylic acid with the alkali metal or ammonium salt thereof or with an alkali metal carbonate or ammonium carbonate or a mixture of these salts of the polybasic carboxylic acid, at least one component of which has at least one free acid group. Suitable acids are oxalic, malonic, succinic, maleic, fumaric, itaconic and citric acids, optionally substituted by a halogen atom or a hydroxyl group.
