Organic phosphates and their preparation.

摘要

Compositions comprising a combination of (i) at least one hydrocarbon-soluble aryl phosphate of the formula (RO)3PO wherein each R is, independently, phenyl or an alkyl-substituted phenyl group; and (ii) at least one hydrocarbon-soluble aryl polyphosphate of the formula <CHEM> wherein each R is, independently, phenyl or an alkyl-substituted phenyl group, Ar is m-phenylene or an alkyl-substituted m-phenylene group, and n is from 1 to 4, and a process for the preparation of such compositions. The combination contains from 2 to 30% by weight of component (i).
