摘要
利用积炭样品的（１３）ＣＣＰ／ＭＡＳＮＭＲ及其浸洗液的１Ｈ、（１３）ＣＮＭＲ测试，研究环氧丙烷与醇合成丙二醇醚时催化剂（ＬＡ－２）的积炭结构及床展不同部位样品积炭的相对量，从而探讨其积炭的机理及催化剂失活的原因．
The coke formed on LA-2 catalysts during the conversion of propylene oxide and alcohols to propylene glycol ethers is studied by 13C CP/MAS NMR spectrostroscopy and 1H. 13C NMR spectrostroscopy for the soluble components in coke. The mechanism of coke formation and the reason of catalyst deactivation are also discussed
