    • A process is described for preparing acylglycinates of the formula (I) wherein R1 is a linear or branched, saturated alkanoyl group having 6 to 30 carbon atoms, or is a linear or branched, singly or multiply unsaturated alkenoyl group having 6 to 30 carbon atoms, and Q+ is a cation selected from the alkali metals Na+ and K+, the process being characterized in that glycine is reacted with fatty acid chloride R1Cl, wherein R1 possesses the definition stated in formula (I), in water and in the presence of a basic alkali metal compound which yields cations Q+ selected from Na+ and K+, but in the absence of organic solvents, at 25-50° C., and the fraction of fatty acid chloride R1Cl containing unsaturated acyl groups R1 having 18 carbon atoms, based on the total amount of fatty acid chloride used, is greater than or equal to 2.0% by weight, and at the same time the fraction of fatty acid chloride containing saturated acyl groups having 8 and 10 carbon atoms, based on the total amount of fatty acid chloride used, is greater than, or equal to in each case 3.0% by weight. Also described are compositions comprising acylglycinates of the formula (I).
    • 描述了制备式(I)的酰基甘氨酸的方法,其中R 1是具有6至30个碳原子的直链或支链饱和烷酰基,或者是具有6至30个碳原子的直链或支链,单或多不饱和链烯酰基 ,Q +是选自碱金属Na +和K +的阳离子,该方法的特征在于甘氨酸与脂肪酰氯R1Cl反应,其中R1具有式(I)中定义的定义,在水中和在 碱性碱金属化合物,其在25-50℃下产生选自Na +和K +,但不存在有机溶剂的阳离子Q +,并且基于具有18个碳原子的不饱和酰基R1的脂肪酰氯R1Cl的级分基于 使用的脂肪酰氯的总量大于或等于2.0重量%,同时含有碳原子数为8和10的饱和酰基的脂肪酰氯的分数,基于fa的总量 使用tty酰氯,大于或等于每种情况下为3.0重量%。 还描述了包含式(I)的酰基甘氨酸盐的组合物。
