菜籽油常压水解制备脂肪酸的研究
Preparation of Fatty Acid by Hydrolysis of Rapeseed Oil under Normal Pressure
摘要
Abstract
[Objective] The research aimed to take the rapeseed oil as raw material for hydrolysis preparation of fatty acid atmospheric pressure.[Method] Fatty acid was produced by hydrolysis of rapeseed oil under normal pressure at the temperature of (95±5)℃.Effects of ratio of oil to water, amount of catalyst and emulsification and time on reaction were studied.[Result] The optimal parameter was as follows: amount of emulsification 4%(W/W), amount of catalyst 15%(W/W), weight ratio of oil to water 1∶ 2, hydrolysis time 17 h.Under the conditions, the acid value of hydrolyzed Jatropha curcas oil reached 180.3 mg/g.[Conclusion] The fatty acids which were commonly used in industry could be produced under atmospheric pressure by hydrolyzing the rapeseed oil.And the conversion rate could reach 93.8%.关键词
