Abstract
Monododecylphosphate (MAP) was synthesized by esterification of phosphoric acid and lauryl alcohol over ion-exchange resin catalyst modified by metal salts. The effects of various loaded metal salts on the yield of MAP were investigated. The results showed that ion exchange resin loaded CaSO4 exhibited good performance. The conversion of lauryl alcohol of 79.4% and the selectivity of MAP of 99.9% could be obtained, respectively after 12 hours reaction under a temperature of 90°C when the load ratio of CaSO4 was 1.2% and the amount of catalyst equaled 3% of the total mass. The conversion of lauryl alcohol could reach 92.3% with 99.9% selectivity of MAP under the conditions above when cyclohexane was used as water removal. Catalytic performance of ion exchange resin catalyst modified by CaSO4 remained stable after 7 times reuse.
