摘要:
The present invention relates to a method for refining polyoxymethylene dialkyl ethers by catalytic hydrogenation using a slurry bed, wherein, using a slurry bed reactor of refining by hydrogenation, an equilibrium system of products containing polyoxymethylene dialkyl ethers is refined by catalytic hydrogenation, so as to remove formaldehyde contained therein. The refining method by hydrogenation described in the present invention is able to remarkably increase the extracting rate of polyoxymethylene dialkyl ethers, and the polyoxymethylene dialkyl ethers obtained after subsequent rectification have purity greater than 99.5%, yield greater than 97% and atom utilization ratio close to 100%.
摘要(中):
本发明涉及一种用于使用淤浆床催化加氢精制聚甲醛二烷基醚,worin的方法,使用通过加氢精制的浆液床反应器中,在产品的含聚甲醛二烷基醚平衡体系进行催化加氢精制,以 除去其中所含的甲醛。 通过加氢精制方法在本发明中所描述的是能够显着提高聚甲醛二烷基醚的提取率,和随后的整流后获得的聚甲醛二烷基醚具有纯度大于99.5%,产率大于97%和原子利用率接近 100%。
