PRODUCTION OF SUBSTITUTED PHENYLENE DIBENZOATE INTERNAL ELECTRON DONOR AND PROCATALYST WITH SAME

摘要

The present disclosure is directed to the production of substituted phenylene aromatic diesters and 5-tert-butyl-3-methyl-1,2-phenylene dibenzoate (or “BMPD”) in particular. The processes disclosed herein produce a liquid BMPD product. The liquid BMPD product unexpectedly creates production efficiencies by reducing the number of production steps, reducing the amount and/or number of reagents required for BMPD production. The liquid BMPD product may also be utilized in procatalyst production yielding similar production efficiencies. The procatalyst composition is subsequently used for olefin polymerization.

1. A process comprising:
combining, under reaction conditions in a first reaction mixture, a first water insoluble solvent, BMC, triethylamine, and benzoyl chloride and forming a liquid BMPD product; adding, under reaction conditions, the first reaction mixture including the liquid BMPD product directly to a second reaction mixture comprising a procatalyst precursor, a halogenating agent, and a second water insoluble solvent; and forming a solid procatalyst composition.
