Abstract:

Ferulic acid was obtained from rice hull with the microwave-assisted extraction method.The solubility data of trans-ferulic acid in 8 binary systems of water and organic solvents, such as methyl acetate, ethyl acetate, butyl acetate, methanol, ethanol, dichloromethane and chloroform were measured from 273.15 K to 333.15 K.The empirical equation was adopted, and the solubilities calculated by the model were in good agreement with experimental data.

摘要： 由微波辅助提取技术应用到从稻壳中提取阿魏酸的过程中，采用溶剂萃取法分离提纯反式-阿魏酸。本文研究了反式-阿魏酸在8种二元物系相平衡数据，采用激光监视技术测定了反式-阿魏酸在乙酸甲酯，乙酸乙酯，乙酸丁酯，甲醇，乙醇，二氯甲烷，三氯甲烷和水混合溶剂中的溶解度，并用简单模型进行了关联，其溶解度关联值与实测值吻合程度良好。
