摘要
以09号蜡和己二胺为原料,在无催化剂、无交换气、常压的条件下合成高熔点相变蜡。通过正交试验设计优化实验方案,然后采用控制单一变量的方法确定的最优工艺条件为：n（己二胺）∶n（09号蜡）=0.65,低温反应温度165-175℃,低温反应时间2.0-2.5h,高温反应温度190-195℃,高温反应时间1.5-2.0h。经过DSC差式扫描量热仪表征,高熔点相变蜡的焓变量大于170J/g,熔点为140-145℃,其焓变量和熔点高于目前国内同类产品。
Using 09# wax and 1, 6-hexanediamine as raw materials, high melting-point wax is syn-thesized under the condition of normal pressure without catalyst and exchange gas, which could be used as a phase change energy storage material. The optimal reaction conditions are determined by orthogonal test design, followed by the single variable method. The mole ratio of 09# wax to 1, 6-hexanediamine is 1： 0.65, and the low-temperature reaction time is 2.0-2.5 h at 165-175℃ ,and the high-temperature reaction time is 1.5-2.0 h at 190-195 ℃. The produced phase change wax is tested by differenti al scanning calorimetry （DSC）. The melting enthalpy is greater than 170 J/g, and the melting point is 140-145℃. The enthalpy variables and melting point are higher than the current domestic similar products.
