Process for preparing n, n'-disubstituted p-quinonediimines, their use and organosilanes containing methacryloxy or acryloxy groups, processes for their stabilization and their preparation |
摘要 |
The invention relates to a process for preparing N,N'-disubstituted p-quinonediimines of general formula I wherein a corresponding N,N'-disubstituted p-phenylenediamine is oxidized in alkaline/alcoholic solution, and also their use. The invention further provides organosilanes containing methacryloxy or acryloxy groups and having general formula II where R3 is a hydrogen atom or a methyl group and R4 and R5 are identical or different alkyl groups having from 1 to 4 carbon atoms and m is equal to 0 or 1 or 2, which organosilanes contain N,N'-disubstituted p-quinonediimines. Processes for preparing and stabilizing organosilanes of general formula II are described.
