摘要:已经开发了基于使用异质铂族催化剂的有效和实用的芳烃加氢方法.Rh / C是最有效的芳环加氢催化剂,可以在中性条件下,在常压至中等h 2压力(<10 Atm)下在i Proh中进行.将各种芳烃(如烷基苯,苯甲酸,吡啶,呋喃)以非常好或极好的收率氢化成相应的环己基和杂环化合物.Ru / C的使用比rh / C便宜,它为氢化包括苯酚在内的芳烃提供了一种有效而实用的方法.在简单过滤后,两种催化剂都可以重复使用数次,而催化活性没有任何重大损失.

摘要:The present invention belongs to the technical field of polymer synthesis, and specifically discloses aliphatic copolycarbonate and a preparation method therefor. The aliphatic copolycarbonate contains a structural unit as shown in formula (1) and a structural unit as shown in formula (2), wherein R1 is a C3-C10 alkylene group, and R2 is an alicyclic group. In the present invention, a specific alicyclic monomer is introduced into a molecular chain of aliphatic polycarbonate, such that a new type of aliphatic copolycarbonate is obtained. The polymer in the present invention has the properties of a relatively high melting point, a relatively high glass transition temperature, relatively high thermal stability, etc., and has relatively good thermal performance.
