摘要:
A process for the monoacylation of water-soluble organic amino compounds with 2,4,6-trifluoro-s-triazine, which comprises introducing all reactants simultaneously and continuously in the amounts necessary for the required throughput into the reaction space and removing the resultant reaction products continuously therefrom.
摘要:
The invention relates to a mixture of nonylated diphenylamines, especially dinonylated diphenylamines, and to a technically advantageous methodological process for the preparation of that mixture by using acid catalysts in small quantities. The mixture is used as an additive for stabilizing organic products that are subjected to oxidative, thermal and/or light-induced degradation.
