胺类催化剂

RIM聚氨酯体系锡/胺类催化剂作用机理的研究

The reaction principle for RIM-PU systems with tin / amine catalysts

胺类催化剂是反应中应用最广泛的一类催化剂。

Tertiary amine is the widest-used catalyst in Baylis-Hillman reaction .

结果表明，有机金属类催化剂可用于催化本体系，而胺类的催化剂不合适；

The results show that the organometal catalysts are suitable for the polyurethane coatings , and the tertiary amine catalysts are not suitable .

然后用一种新型醇胺类相转移催化剂，分别以盐酸和水作为介质，在90～110℃水解后得到了高纯度的苯甲醛。

Then highly purified benzaldehyde can be obtained through hydrolysis in the medium consisting of hydrochloric acid and water , under temperature at the range of 90 ~ 110 ℃ in presence of phase transfer catalyst .
