Abstract:以醋酸为改性介质,从醇油摩尔比、催化剂质量分数、酯交换温度及时间等因素出发,并辅以热重分析仪、X射线衍射仪、N2吸附仪和哈米特指示剂等催化剂表征手段,通过酯交换实验系统研究改性电石渣催化酯交换的特性。酯交换原料油(花生油)脂肪酸中的碳原子长度主要为16~18碳;醋酸改性后,电石渣主要成分为(CH3COO)2Ca·0.5H2O,经800℃煅烧活化处理后转变为CaO,比表面积为19.07 m2/g、比孔容积为0.081 4 cm3/g,且能够表现出比未改性电石渣煅烧产物更强的催化酯交换性能。在醇油摩尔比15、催化剂质量分数4%、酯交换温度59℃、酯交换时间2 h的工况下,醋酸改性电石渣催化酯交换能取得甘油收率为96.79%,且重复使用5次时,甘油收率仍能达到92.90%。
