摘要
鉴于脂肪酸甲酯磺酸盐(MES)可以从廉价的动植物油中制取,对其生产的研究已有30多年。但是,早期研究脂肪酸甲酯磺酸盐生产的成果不理想,产品色泽深,从原料甲酯(ME)到MES的收率也低。消费者认为色泽浅的产品纯度高,所以色泽深不受欢迎。MES要想成为消费品中传统表面活性剂的一种替代品就必须先解决色泽深的问题。ME到MES的收率低是一个经济问题,因为它会显著增高MES的成本。收率低的原因是MES中的酯键断裂而生成甲醇和羧酸磺酸盐(二盐)。二盐无优良表面活性,所以生成二盐被视为收率的损失。因此,MES成功产业化的基本前提就是解决好色泽和收率这两个关键问题。
Because methyl ester sulfonates （MES） can be made from low cost vegetable and animal fats, production of methyl ester sulfonates has been studied for over 30 years. However, early efforts to manufacture MES resulted in products with high color and low conversion of methyl ester （ME） feedstock to MES.Dark color is undesirable because consumers equate light colors with product purity. Therefore, light color is mandatory if MES is to become a replacement for traditional surfactants in consumer products. Low conversion of ME to MES is an economic issue as it effectively increases the cost of MES. The principle conversion problem has been the breaking of the ester bond in MES to form methanol and alpha sulfo sodium carboxylate （di - salt）. Di - salt does not have good surfactant properties and is viewed as a yield loss. A solution to the color and di - salt problems was an essential condition for commercial utilization of MES.
