室温下FeCl3用于催化三聚异丁烯(TIB)与乙酸酐的酰化反应.发现FeCl3在所研究的催化剂中是最有效的.考察了FeCl3的用量、乙酸酐的用量和反应时间等因素对该酰化反应的影响.该反应产生一种混合物,其中两种产物是主要的.当反应在1 mmol TIB/15 mmol乙酸酐/0.50 mmol FeCl3/0.43 g氯仿和25℃下进行2 h时,生成的两种主要产物的总产率为69%.另外,反应在由沸石和FeCl3或P2O5组成的共催化剂存在下进行.该反应也用HY和H-β沸石之类的多相催化剂进行了尝试.负载FeCl3的HY和H-β沸石催化剂比FeCl3具有更高的催化活性和选择性.
FeCl3 was used to catalyze the acylation of triisobutylene (TIB) with acetic anhydride at room temperature.It was found that FeCl3 was the most effective catalyst in the study.The effects of FeCl3 dosage, acetic anhydride dosage and reaction time on the The reaction yielded a mixture in which the two products were predominant.When the reaction was carried out for 2 h at 1 mmol TIB / 15 mmol acetic anhydride / 0.50 mmol FeCl3 / 0.43 g chloroform at 25 ° C, the reaction was generated The overall yield of the two main products was 69% .In addition, the reaction was carried out in the presence of a co-catalyst consisting of zeolite and FeCl 3 or P 2 O. The reaction was also attempted with heterogeneous catalysts such as HY and H-β zeolites The FeCl3 supported HY and H-β zeolite catalysts have higher catalytic activity and selectivity than FeCl3.
