三醋酸甘油酯制备

1、由甘油与乙酸酯化而得。将甘油预热到50-60℃后，加入乙酸、苯和硫酸。加热搅拌回流脱水，脱水完后回收苯，再加入乙酐，加热4h。冷却后用5%碳酸钠中和pH至7，分去水层，粗油用氯化钙干燥。减压蒸馏，收集128-131℃（0.93kPa）馏分，即为甘油三乙酸酯。 2、由醋酐与热甘油酯化后经真空蒸馏提纯而得。 3. 酯化反应　向塔釜中分别加入一定量的甘油、冰醋酸（醇酸摩尔比为1∶4）、固载型杂多酸催化剂（醇质量的2.5%）和带水剂甲苯（温度调节剂），加热塔釜液，使釜液处于微沸或沸腾状态下，进行反应精馏操作。塔顶分水器中的酯相返回精馏塔，水相采出。当塔顶分水器无水滴分出时，向塔釜中加入一定量的醋酐，继续反应4h后，终止酯化反应，冷却后，即得粗酯。 4. 粗酯精制　粗酯经冷却，过滤出固体催化剂滤液。先进行常压精馏，回收过量的冰醋酸和带水剂甲苯，当馏出液很少时改为减压精馏，进一步脱除冰醋酸，控制釜液温度在100～120℃以内，无馏出液时停止蒸馏操作；釜液温度降至100℃以内，加入一定量的脱色剂活性炭，搅拌一定时间后，冷却，滤出脱色剂，得产品三醋酸甘油酯。
