Continuous process for the preparation of polytrimethylene ether glycol

   
   

The invention is a continuous process for the preparation of polytrimethylene ether glycol from 1,3-propanediol reactant. In addition, the invention is directed to a continuous multi-stage process comprising reacting at least one reactant in a liquid phase in an up-flow column reactor, and forming a gas or vapor phase by-product wherein the gas or vapor phase by-product is continuously removed at the top and at least one intermediate stage.

Вымыслом будет непрерывный процесс для подготовки гликоля эфира polytrimethylene от реактанта 1,3-propanediol. In addition, вымысел направлен к непрерывному многошаговому процессу состоя из реагирующ по крайней мере один реактант в жидкостном участке в реакторе колонки up-flow, и формирующ субпродукт участка газа или пара при котором субпродукт участка газа или пара непрерывно извлекается на верхней части и по крайней мере одном промежуточном этапе.
