| Abstract: | Di(2 - ethylhexyl)sebacate is synthesized from sebacic acid and 2 - ethyl hexanol on a series of solid superacids and the catalytic activity of S042-/TiO2 - A12O3 superacid is studied.The effects of the reaction conditions on reaction are examined. The optimum reaction conditions are determined as follows: molar ration of alcohol to acid is 3.5: 1,the amount of catalyst used is 1.0 g/mol sebacic acid, the volume of water carrying agent is 10 mL and the reaction time is 4.5 h.Under such optimum condition,the conversion is 98.5% . |
