Salts of N-acetyl cysteine and N-acetyl homocysteine are prepared by reacting acetonitrile with cysteine or homocysteine in an aqueous or aqueous-organic medium adjusted to a pH in the range of 8 to 10 with a base supplying the cation of the salt. The reaction is carried out at a temperature in the range of 0.degree. C. to the boiling temperature of the reaction mixture.
N-乙酰半胱氨酸和N-乙酰同型半胱氨酸的盐类是通过在pH值在8到10的水性或水性-有机介质中,用碱提供盐的阳离子,将乙腈与半胱氨酸或同型半胱氨酸反应而制备的。反应在0℃到反应混合物的沸点温度范围内进行。
