Process for the Preparation of the Alkoxyamine 2-Methyl-2-[N-(Diethoxyphosphoryl-2,2-Dimethylpropyl)-Aminoxy] Propionic Acid |
摘要 |
The present invention relates to a process for the preparation of the alkoxyamine 2-methyl-2-[N-(diethoxy-phosphoryl-2,2-dimethylpropyl)aminoxy]propionic acid or of its salts comprising a stage of saponification of an azo compound in the presence of a base, a stage of photolysis of the salt resulting from the saponification stage in the presence of N-(tert-butyl)-1-diethylphosphono-2,2-dimethylpropyl nitroxide and optionally a stage of acidification of the salt of the alkoxyamine obtained on conclusion of the photolysis stage. The alkoxyamine or its salts can be used as radical polymerization initiators.
