Production process for (poly)alkylene glycol monoalkyl ether |
摘要 |
The present invention provides a process for producing a (poly)alkylene glycol monoalkyl ether with high selectivity and high yield. In this process, the (poly)alkylene glycol monoalkyl ether is produced by reacting an olefin and a (poly)alkylene glycol in the presence of a catalyst, wherein: 1) a crystalline metallosilicate is used as the catalyst, and at least a portion of the used catalyst is regenerated, and the regenerated catalyst is recycled as the catalyst for the reaction; or 2) the reaction between the olefin and the (poly)alkylene glycol is carried out in the presence of either or both of a (poly)alkylene glycol dialkyl ether and an alcohol. |
