【摘要】 EO加合数(n_EO=3,5,7)对油醇醚硫酸盐性能的影响，通过对不含EO的油醇硫酸盐（SOS）与油醇醚硫酸盐（OE_nS）进行性能研究，结果表明：OE_nS较SOS在硬水中的稳定性好；EO含量越多，OE_nS的Krafft点越低，耐盐耐碱性越好，其中OE₇S Krafft点低于0℃,耐盐性大于300 g/L,耐碱性高达150 g/L;SOS对JB-01去污性较好，OE_nS对JB-03去污性较好；OE_nS相较于SOS体系的润湿性，乳化性，起泡性及稳泡性较差。更多还原

【Abstract】 Research of EO addition number(n_EO =3,5,7) effect on the performance of oleyl ether sulfate, and the properties of sodium oleyl sulfate（SOS） without EO and oleyl ether sulfate（OE_nS） were studied.Results showed that the stability of OE_nS was better than that of SOS in hard water, and the more EO content, the lower the Krafft point of OE_nS,the better the salt and alkali resistance, where the Krafft point of OE₇S was less than 0 ℃,the salt resistance was more than 300 g/L,and the alkali resistance was up to 150 g/L.SOS showed better detergency for JB-01,while OE_nS had better detergency for JB-03.Compared with SOS system, OE_nS had poor wettability, emulsification, foamability and foam stability.更多还原
