摘要： 在一定的温度和压力条件下,以及特制的均相催化剂作用下,直接由蓖麻油酸甲酯得到了产物蓖麻油酸甲酯乙氧基化物(ECAME-10)。通过皂化值、气相色谱(GC)和1HNMR测定了ECAME-10的平均环氧乙烷(EO)加合数,在不同pH条件下测定了ECAME-10的耐酸耐碱性,并跟踪拍摄了不同pH溶液不同阶段的外观照片,同时测定了不同阶段溶液的表面张力。结果显示:ECAME-10有较强的抗水解能力,当pH=4~9时,ECAME-10的水解较慢,8周后其水解率在40%以下;水解后的表面张力数据表明,水解后溶液的表面张力可保持稳定。

Abstract: Ethoxylated ricinoleic acid methyl esters (ECAME-10) obtained directly from castor oil acid methyl esters by the use of a special homogeneous catalyst.The average ethylene oxide (EO) adduct number of ECAME-10 was determined by saponification value,gas chromatography (GC) and 1HNMR.The hydrolysis resisting capacity of ECAME-10 was investigated under different pH value conditions.The appearance changes of ECAME-10 solution under different storing time periods was tracked and photographed and surface tension of different stages of the solution at different stages was measured.Results showed that the hydrolysis resisting capacity of ECAME-10 is rather strong.The hydrolysis rate of ECAME-10 is below 40% in pH value range of 4-9 after eight weeks.Surface tension of solutions can be kept stable after the hydrolysis reaction.

Key words: ethoxylated ricinoleic acid methyl esters, hydrolysis resisting capacity, surface tension
