| titleOfInvention | Chemically stabilized azulmic acids, processes for their preparation and their use |
| abstract | A B S T R A C T The invention relates to certain new azulmic acids stabilised by reaction with aminoplast-forming agents and carbonyl compounds or condensation products there-of, to a process for their preparation and to their use for various purposes. The compounds containing from 0.5 to 55 per cent by weight of ionic groups of the general formula (F1) in which R represents hydrogen, ammonium, one equi-valent of a protonated or quaternised organic nitrogen base or of a sulphonium cation or one equivalent of a metal cation, and containing from 0.5 to 15 per cent by weight of groups formed by decarboxylation reactions of the formula (F2) can be obtained by various processes, e. g. a process in which a modified azulmic acid optionally containing an additive and containing from 0.5 to 55 per cent by weight of ionic groups is reacted, in an aqueous medium, optionally in the presence of an additive and if appropriate in the presence of a catalyst, and if appropriate in the presence of a chain stopper, with an aminoplast-forming agent and a carbonyl compound or a freshly prepared, optionally chemically modified condensation product thereof. Numerous substances according to the invention can be used as flameproofing agents or anti-ageing agents for preventing oxidative degradation in the most diverse polyurethane plastics, vinyl polymers, polyamide plastics, rubbers and epoxide resins. Moreover, adducts of azulmic acids, stabilised according to the invention, with such compounds as, for example, phospholine oxide-phosphonic acids are suitable as catalysts for the heterogeneous catalysis of the reaction of isocyanates and polyisocyanates to give polycarbodiimides. Substances according to the invention can furthermore be employed as supports for numerous catalysts, mixed catalysts being formed which can be used in many ways. |
