溴乙酸合成路线
溴乙酸上下游产品
溴乙酸上游产品
溴乙酸下游产品
溴乙酸制备
1.以醋酸为原料，在吡啶存在下滴加溴素进行反应制取之。
2.由氯乙酸与氢溴酸反应而得。
3.由羟乙酸与氢溴酸反应而得。
4.制法：
于装有搅拌器、温度计、回流冷凝器（连一道气管至溴化氢气体吸收装置）、滴液漏斗（连一玻璃管通至瓶底部）加入冰醋酸（2）131g（2.2mol），醋酸酐27g（0.26mol），吡啶0.25mL。将混合物加热至沸，先加入1mL溴，使反应开始，待溴的颜色消失，再慢慢滴加溴（共140g，0.875mol），约2h加完。加完后继续回流反应直至溴的颜色消失。冷却，慢慢加入10mL水以分解酸酐。蒸馏除去乙酸和水，剩余物为粗品溴乙酸。冷后固化，粗品蒸馏，收集202～204℃的馏分，或减压蒸馏收集117～118℃/2.0kpa的馏分，得溴乙酸（1）100g，mp50℃，收率83%。
