【摘要】 绘制了2,6-二异丙基萘(2,6-DIPN)与2,7-二异丙基萘(2,7-DIPN)二元体系的固液相图,测定了2,6-DIPN和2,7-DIPN二元混合物体系的低共熔点,并用理想溶液模型进行了关联。结果表明,2,6-DIPN与2,7-DIPN二元体系固液平衡相图为简单低共熔混合物相图,低共熔点温度为-19.5℃,组成为2,7-DIPN12.2%(质量分数,下同),2,6-DIPN87.8%,由试验数据拟合得到2,6-DIPN的熔化焓为4.878kJ/mol。更多还原

【Abstract】 Solid-liquid equilibrium data and eutectic point of 2, 6-DIPN and 2, 7-DIPN binary systems were measured. Ideal solution model was used to correlate the data. The experimental results showed that binary system of 2,6-DIPN and 2,7-DIPN was a simple eutectic phase diagram, the mixture was a eutectic system with x₁=0.878, x₂=0.122 and eutectic temperature was -19.5 ℃ . The fusion enthalpy of 2,6-DIPN was 4.878 kJ/mol.更多还原
