Reactive Distillation of a Carboxylic Acid and a Glycol |
摘要 |
Disclosed is a process for producing glycolate ester oligomers. The process comprises reacting ethylene glycol and glycolic acid to produce a stream of glycolate ester oligomers and glycolic acid oligomers while simultaneously removing water. The stream of glycolate ester oligomers and glycolic acid oligomers has a low concentration of water and glycolic acid-ends, and thus is useful in a subsequent hydrogenation reaction to produce ethylene glycol.
