摘　　要：为得到甲基对苯二酚的准确、完整的溶解度数据，以制备高质量的甲基对苯二酚，测定了甲基对苯二酚在苯、氯仿、水、乙醇和乙醚等溶剂中的溶解度，给出了不同温度下甲基对苯二酚在苯和氯仿中的溶解度方程，得出甲基对苯二酚易溶于水、乙醇和乙醚的结论，为液固相平衡、结晶过程研究和工程设计提供了依据．另外，经粗略估算表明，甲基对苯二酚与苯形成非理想溶液，而与氯仿形成理想溶液．In order to obtain the perfect solubility data of methylhydroquinonl to prepare high quality methylhydroquinonl, the solubility of methylhydroquinonl in benzene,chloroform,water,ethyl ether and ethyl alcohol has been measured.The equations of solubility of methylhydroquinonl in both benzene and chloroform at different temperatures arebeen given.The conclusion that methylhydroquinonl easily dissolves in water,ethyl ether and ethyl alchol is reached.It provides a base for the research work of phase equilibrium of liquid-solid,crystallization process and engineering design.In addition,according to rough calculation,methylhydroquinonl and benzene form a non-ideal solution,while methylhydroquinonl and chloroform form ideal solution.
