摘要
Abstract
With fermentation produced lactic acid and natural menthol as main raw materials, L-menthyl lactate was synthesized by direct esterification. The effects of the water stripping agent, mass ratio of lactic acid to menthol, reaction temperature and reaction time on conversion were studied. The results showed that using CCl4 as the water stripping agent,m(lactic acid): m (menthol) = 1.2:1 ,at reaction temperature of 110℃ for 3 h, the conversion of menthol to L-menthyl lactate achieves 75.5 %. The purity of the product can achieve 99.6% after vacuum distillation and recrystallization. The product was used tentatively in personal care products such as shower gel, skin care lotion, and toilet powder freshener. Comparison was made on the performance of L-menthyl lactate with that of menthol. Results showed that the L-menthyl lactate has advantages such as mild and persistent freshening action and feeling on human skin.关键词
