In-situ removal of water or methanol in condensation reactions is a most suited method to intensify
production of e.g. esters and ethers.
Conventional esterification processing
formed during the
condensation reaction a higher
yield of product is achieved and
Downstream, post-treatment operations
possibly less intense catalytic
measures are necessary.
