摘　　要：对不同平均环氧乙烷（EO）加合数的蓖麻油酸甲酯乙氧基化物（ECAME）的洗涤性能进行了测定，并考察了其在不同pH条件下的抗水解能力．结果表明，平均EO加合数为14的蓖麻油酸甲酯乙氧基化物（ECAME-14）的洗涤能力最好．在pH为4-9的溶液中放置4周，ECAME-14水解率很低．在碱性条件下，其表面活性被削弱，但在酸性条件下，其表面活性增强．The washing properties of different average ethylene oxide （EO） adduct number of ethoxylated castor oil acid methyl esters （ECAME） was tested and the hydrolysis resistant ability of ECAME was investigated under different pH. The results showed that ethoxylated castor oil acid methyl esters with 14 of EO adduct number （ECAME-14） had the best washing property. The hydrolysis rate of ECAME-14 was low under pH=4- 9 for 4 weeks. Under alkaline condition, the surface activity of ECAME-14 was weakened while its surface activity was enhanced under acidic condition.
