离子液体[Emim]Br中蓖麻油裂解制备仲辛醇的工艺
Preparation of 2-octanol through Castor Oil Pyrolysis in Ionic Liquid [Emim]Br
摘要
Abstract
The technological conditions for producing 2-octanol from castor oil in ionic liquid,[Emim]Br,was studied through single factor experiments and orthogonal experiments. The mass ratio of castor oil acid to ionic liquid,pyrolysis reaction time,temperature,and the ratio of castor oil acid to NaOH were investigated in detail. The optimal technological conditions obtained are as follows:the temperature was 300,℃,pyrolysis time was 90,min,the mass ratio of castor oil to ionic liquid was 1∶1,and the ratio of castor oil to alkali(6,mol/L)was 1∶1.5. The yield of 2-octanol was about 28.2%under the optimal technological conditions. In addition,the traditional solvent cresol was replaced by ionic liquid [Emim]Br,and pollution was reduced with this clean production method. The ionic liquid can be recycled and used again.关键词
