摘要: 肌醇生产的原料——植酸钙的杂质含量较高,所得肌醇的粗品杂质含量也较高.因此为肌醇的除杂、纯化、分离带来了困难.除杂的方法有沉淀法、离子交换法等.本文试图从肌醇-乙醇-水三元体系的相图中,寻求一种纯化分离肌醇的新方法.

Abstract: The solubilities and refractive indices of the saturated solutions of C6H12O6-C2H5OH-H2O ternary system have been determined.The solubility curve and refractive index curve of the system at 35℃ consist of 3 branches,corresponding to C6H12O6·10H2O, C6H12O6·H2O,and C6H12O6 respectively.The composition of eutectic solutions at two non-variant points is(C6H12O6:7.07%,C2H5OH:17.07%)and(C6H12O6:0.05%,C2H5OH: 91.21%).
