ABSTRACT:
Disubstituted monochlorotriazines such as 2-chloro-4-mesitoxy-6-glycidoxy-1,3,5-triazine are prepared in organic solution by first combining a monoorganoxy dichlorotriazine with an aqueous alkali metal hydroxide solution in a specific concentration and molar ratio, and adding to the mixture thus produced a hydroxyaliphatic or hydroxyaromatic compound, preferably glycidol, in the presence of at least one hydrophilic phase transfer catalyst such as tetra-n-butylammonium bromide. The reaction can be integrated with either or both of a prior step of dichlorotriazine preparation and a subsequent step of capping a hydroxy-terminated polymer, especially a polyphenylene ether.
