摘　　要：以蛋白酶、纤维素酶为研究对象,系统研究了脂肪醇聚氧乙烯醚硫酸钠(AES)、十二烷基苯磺酸钠(LAS)、α-烯烃磺酸盐(AOS)、脂肪醇聚氧乙烯醚(AEO_(7))分别与蛋白酶、纤维素酶的相互作用影响,同时优化加酶洗衣液的基础配方。研究结果表明:对纤维素酶、蛋白酶失活影响顺序均是:LAS>AOS>AES>AEO_(7);AEO_(7)与阴离子表面活性剂复配后,可以明显提高酶制剂在阴离子表面活性剂中的酶活力;氯化钙可以提高酶制剂在洗衣液中的稳定性;在无磺酸体系的洗衣液中,优化出较佳的洗衣液配方是AEO_(7)/AOS、蛋白酶、纤维素酶分别为1︰2、0.06%、0.04%。The interaction of fatty alcohol polyoxyethylene ether sulfate(AES),sodium dodecyl benzene sulfonate(LAS),α-olefin sulfonate(AOS)and fatty alcohol polyoxyethylene ether(AEO_(7))with protease and cellulase was studied systematically,and the basic formula of enzymatic laundry detergent was optimized.The results showed that the order of influence on the inactivation of cellulase and protease was LAS>AOS>AES>AEO_(7);The combination of AEO_(7) and anionic surfactants can significantly improve the enzyme activity of enzyme preparations in anionic surfactants.Calcium chloride can improve the stability of enzyme preparation in laundry detergent.In the sulfonic acid-free laundry detergent,the optimal detergent formula is AEO_(7)/AOS,protease and cellulase 1:2,0.06%and 0.04%,respectively.
