溴乙酸甲酯制备

1.由乙酸溴化后再与甲醇进行酯化反应而得。将冰醋酸、乙酐、赤磷和几片沸石加入干燥反应器，加热回流，当温度升至60-70℃时开始缓缓滴加溴素，加完后保温约1h。冷却过滤，然后减压蒸馏得溴乙酸。将溴乙酸和甲醇加入四氯化碳中，再加入硫酸，加热回流脱水，脱水完毕，将四氯化碳蒸出，再加入甲醇回流1h，回收甲醇，剩余物经洗涤、干燥后进行减压蒸馏，即得成品。

2.在一干燥的三口烧瓶上安冷凝器、温度计、分液漏斗等。将冰乙酸、醋酐、赤磷、几片沸石加入，然后在沙浴上回流，当温度达60～70℃时开始从分液漏斗中慢慢滴入溴，加完后保温30～60min，冷却过滤，然后减压蒸馏得溴乙酸。将四氯化碳、溴乙酸、甲醇、硫酸混合在沙浴上回流脱水，脱水毕，将四氯化碳蒸出，再加入甲醇回流1h后，回收甲醇，剩余物经洗涤、干燥后，减压蒸馏得成品。过程反应式为：
