ABSTRACT:
A process for the production of a carboxylic acid in the presence of solid catalyst particles that employs a flash step with a liquid wash is disclosed. This process helps prevent the buildup of deposits of solid catalyst particles, attrited solid catalyst particles, and heavy by-products in the flash zone. This invention is useful for the production of carboxylic acids, especially acetic acid.
