摘要
本工艺成功解决了传统生产工艺中催化剂与丙二醇难以分离,导致丙二醇产率低、纯度低、不能连续生产的问题。生产的丙二醇的质量更好,节能、产率高,废物实现零排放,实现了连续生产。
The new process successfully solved the problem that the yield of propylene glycol was low and hard to continuously produce, which was caused by the difficult separation of the catalyst and propylene glycol. There were many advantages such as better waste and continuous production. quality, high yield, energy conservation, with zero
