Recovery and Esterification of Ethanoic Acid in waste Liquid by Extraction

聚戊二酸二乙二醇酯用戊醇萃取法回收废液中的乙酸并酯化为乙酸戊酯

Different pre-treatment methods of the granular sludge was done to suppress the production of methane and stop the process at ethanoic acid stage .

本研究利用厌氧颗粒污泥作为接种污泥，通过不同方式的预处理来抑制产甲烷菌，从而使厌氧消化过程停留在产氢产乙酸阶段。

Methods : The analgesic effects were assessed by hot-plate test in mice and twisting response induced by ethanoic acid in mice .

方法：采用冰醋酸扭体法和热板法对小鼠进行镇痛试验；采用二甲苯耳肿法和角叉菜胶足跖肿胀法对小鼠进行抗炎试验。

When the microwave irradiation power change from 153 W to 900 W , ethanoic acid 10 min esterifying ratio only increase 6 % , which draw a conclusion that the microwave irradiation carboxylic esterifying is not a heating action process .

当微波辐射功率从153W增加到900W时，10min乙酸丁酯化率只增加6%，这一实验结果说明微波辐射脂肪酸醇的酯化过程不存在微波至热作用。

The esterification reaction between ethanol and ethanoic acid to ethyl acetate is reversible . Ethyl acetate , ethanol and water can form binary or ternary azeotropes . Therefore , it is very difficult to obtain ethyl acetate of high purity .

乙醇和乙酸合成乙酸乙酯的反应是可逆反应，乙酸乙酯、乙醇和水会形成二元或三元恒沸物，所以获得高纯度的乙酸乙酯非常困难。

We try to research product C distributions , the residual structure , the reducible sugar output , the ethanoic acid output change through changing reactant quality , the reaction time , the reaction temperature , the reactant particle size , the oxidant amount used , the water volume added .

考察了反应物质量、反应时间、反应温度、反应物粒径、氧化剂用量、反应管中水的体积等反应影响因素对产物C分布、残渣结构、还原性糖产量、乙酸产量的影响。
