CATALYST RECOVERY IN THE CARBONYLATION OF CHLOROBUTENES TO PENTENOYL CHLORIDE IN THE CARBONYLATION OF CHLOROBUTENE WITH PENTENOYL CHLORIDE

摘要

Treating the distillation end product with hydrochloric acid, converting the palladium component to crotylpalladium chloride, and using the crotylpalladium chloride as a catalyst during the carbonylation to convert the chlorobutene to the 3-pentenoyl chloride,
