ABSTRACT:
Included is a process to prepare a halogenated phosphorate-containing product comprising serially contacting (a) a triol with a phosphorus trihalide, (b) a halogenating agent and (c) an oxirane, under conditions sufficient to prepare the halogenated phosphorate-containing product. For example, 2-methyl-2-(hydroxymethyl)-1,3-propanediol, phosphorus trichloride, bromine and ethylene oxide can be employed to prepare a mixture of (2,2-bis(bromomethyl)propyl)(2-bromoethyl)(2-chloroethyl) phosphorate and (2-bromoethyl)bis(2-chloroethyl)phosphorate.
