【摘要】 <正> 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.肌醇自制,白色结晶状粉末,mp(223.16±2.0)℃(文献值,223～226℃).元素分析测定更多还原

【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%).更多还原
