本文研究用HA型固体酸催化合成顺丁烯二酸二(2-乙基己) 酯。催化剂用量为0.4克(以每摩尔马来酸酐计);在135°-145℃下将2-乙基己醇与马来酸酐加热反应(4.5小时);酯产率可达理论值的95％以上。对酯产物进行了沸点、比重、折光率的测定,还进行了元素分析、红外光谱和核磁共振谱的分析,实测结果是令人满意的。 In this paper, the catalytic synthesis of bis (2-ethylhexyl maleate) catalyzed by HA solid acid was studied. The catalyst was used in an amount of 0.4 g (based on maleic anhydride); 2-ethylhexanol was reacted with maleic anhydride (4.5 hours) at 135 ° -145 ° C .; the yield of the ester was up to 95% the above. The boiling point, specific gravity and refractive index of the ester product were measured. The elemental analysis, infrared spectrum and nuclear magnetic resonance spectrum were also analyzed. The experimental results were satisfactory.
