摘要:
The present invention relates to a process for production of carboxylic acid aryl esters which comprises reacting a basic salt of a basic compound selected from alkali metal or alkali earth metal hydroxides, oxides, and carbonates with a carboxylic acid having at least one carboxyl group with a diaryl phosphite compound represented by the following general formula (2): where each R independently represents a hydrogen atom, halogen or alkyl group, n is 1, 2 or 3, and when there exist a plurality of halogen and/or alkyl groups as R, they may be the same or different.
摘要:
A process for production of carboxylic acid aryl esters which comprises reacting a carboxylic acid having at least one carboxyl group with a di- or tri-aryl phosphite compound, in the presence of a basic compound and/or water. The carboxylic acid aryl esters can also be produced by reacting a carboxylic acid or a basic salt thereof with a diaryl phosphite compound.
摘要:
Flame retardant compounds obtained by reacting bisphenol A, diphenyl carbonate and a phosphoric acid ester represented by the following general formula (1): where R 1 -R 6 may be the same or different and each independently represents hydrogen or methyl, a process for their production, and flame-retarded organic polymer materials containing them are provided.
