| Abstract: | Tributyl citrate was synthesized with benzyl sulfonic acid funcitionlized MCM-41 molecular sieve(SBM)as catalyzed.The results showed,when n(acid)∶n(alcohol) =1.0∶8.0,w(cat)%=3%,reaction time 7h,they were good catalysis resulet,esterification yield was 93%.And the catalyst can be reused,repeated five times,the esterification rate remains at 76.3 %. |
