Title:
CONTINUOUS CARBONYLATION METHOD
Document Type and Number:
Japanese Patent JP2019116486
Kind Code:
A
Abstract:
To provide a method for continuous carbonylation of an epoxide or lactone feedstock.SOLUTION: There is provided a method for monitoring and maintaining continuous carbonylation of an epoxide or lactone feedstock. The method includes measuring parameters affecting the rate of carbonylation reaction and adding supplemental replacement catalyst replacement components to maintain a constant rate of carbonylation. There is provided, in the specification, a carbonylation method that employs a two-component catalyst system comprising a Lewis acid and a metal carbonyl. In some aspects, such the method is a continuous carbonylation method in which the epoxide and carbon monoxide are fed, and carbonylation reaction products are continuously produced.SELECTED DRAWING: None
