Catalytic Property of Titanyl Acetate in the Transesterification Reaction of Dimethyl Carbonate and Phenol
摘要
Abstract
Titanyl acetate was prepared through the solvothermal reaction between titanium(Ⅳ) n-butoxide, acetic anhydride and distilled water. Titanyl acetate was firstly used in the transesterification reaction of dime-thyl carbonate and phenol to diphenyl carbonate and exhibited excellent performance. When titanyl acetate amount is 0. 10 g, the phenol conversion reaches to 47. 8% and transesterification selectivity is 99. 9% with trace anisole. Based on the results of FTIR, solid state 13 C NMR, titanyl acetate reacts firstly with phenol. The acetate group of titanyl acetate is replaced by phenoxy group and generates phenoxy titanium complex. It could be considered that phenoxy titanium complex is the real catalyst for the transesterification of dimethyl carbonate and phenol with good resuability.关键词
