from VIP Journal Professional Edition
Author:
yanlian , Zhang Min , Ding Longfu
Abstract:
The synthesis of Tri-n-butyl citrate was studied. The conditions of catalyst dosage, reaction temperature and reaction time were tested. On this basis, the acetylation reaction of Tri-n-butyl citrate was studied. The reaction catalyst, feed ratio of raw materials, reaction temperature, reaction time and other conditions were tested. It provides necessary data for industrial production.Key words:

Summary:
The present invention discloses a catalyst for the synthesis of tributyl citrate and a preparation method thereof. The catalyst uses a strongly acidic mesoporous material prepared by a hydrothermal synthesis method as a carrier, and is chemically bonded on the mesoporous material carrier Acidic ionic liquid, the bonding method of the acidic ionic liquid is surface modification, and the mesoporous material is any one of mesoporous silicon, mesoporous zirconium, mesoporous titanium, the acidic ionic liquid is an ionic liquid containing phosphate or sulfate. First, the conventional hydrothermal method uses zirconium, titanium or silicon precursors and octyltrimethylammonium bromide to prepare a mesoporous material carrier; then acidic ionic liquid surface modification: the mesoporous material carrier is KH-550 with a silane coupling agent, After the toluene reaction is sufficient, it reacts with 1, 3-propane sultone or 1, 4-butane sultone and finally reacts with an ionic liquid containing strongly acidic groups to obtain a strongly acidic mesoporous. The conversion rate of citric acid after use is 90 ~ 99%.
