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.
本发明公开了一种生产乙二醇酸酯寡聚体的方法。该方法包括反应乙二醇和乙醇酸以产生一流的乙二醇酸酯寡聚体和乙醇酸寡聚体,同时去除水。该流的乙二醇酸酯寡聚体和乙醇酸寡聚体具有低水和乙醇酸端基浓度,因此在随后的氢化反应中用于生产乙二醇。
