Abstract
Sodium caprinoyl/lauroyl glutamate was synthesized under alkaline condition with sodium glutamate and capric/lauric fatty acid chloride produced from camphor tree seed kernel oil by saponification and acyl chlorination.The effects of reaction temperature,pH,reaction time,volume ratio of acetone to water and molar ratio of sodium glutamate to capric/lauric fatty acid chloride on the synthesis rate of sodium caprinoyl/lauroyl glutamate were studied.The optimal synthesis conditions were as follows:reaction temperature 45 ℃,reaction time 3 h,pH 10-11,volume ratio of acetone to water 2∶ 1 and molar ratio of sodium glutamate to capric/lauric fatty acid chloride 2∶ 1.Under the optimal synthesis conditions,the synthesis rate reached 89.2%.The product was determined as sodium caprinoyl/lauroyl glutamate by infrared spectrometry and mass spectrometry.
