摘要
以脂肪醇聚氧乙烯醚(AEO9)、氧气和氢氧化钠为原料,在自制的Pd/C催化剂作用下催化氧化制备醇醚羧酸盐(AE9C)阴离子表面活性剂。考察了反应条件对产品收率的影响,并研究了AE9C与双癸基二甲基氯化铵(DDMAC10)复配体系的润湿、乳化和泡沫性能。结果表明较佳的反应条件为:温度70℃、压力0.08 MPa、反应时间4 h,产品的收率可达85%。AE9C与DDMAC10复配具有较好的协同效应。
Ethoxylated fatty alcohol carboxylate （ AE9 C） , an anionic surfactant was synthesized by using AEO9, O2 and NaOH as starting materials with self- made Pd/C catalyst. Reaction conditions were investigated. AE9C product was blended with didecyldimethylammonium chloride （DDMAC10）. The properties of the blended surfactant, such as foaming power, wetting power and emulsifying power were measured. The experiment results showed that the optimum reaction conditions to prepare AE9C are temperature 70 ℃; pressure 0. 08 MPa; reaction time 4 h. Yield up to 85 % can be achieved. The performance of the blended surfactant of AE9C with DDMAC10 showed that such blending has significant synergistic effect.
