摘要
利用正交试验优化了硬脂酸三乙醇胺酯的合成工艺:反应温度160℃、反应时间6 h、n(硬脂酸)∶n(三乙醇胺)=1.4∶1,催化剂用量0.1%(对反应物质量).以V(氯仿)∶V(甲醇)=25∶1的混合溶剂作为柱层析的洗脱剂,成功分离出高纯度的三酯、双酯和单酯,并利用高效液相色谱(HPLC)、红外光谱(IR)及质谱(MS)对其进行了定性分析.
The synthesis conditions of triethanolamine esters of stearic acid were optimized by orthogonal experiment： molar ratios of stearic acid and triethanolamine 1.4： 1, reaction temperature 160 %, reaction time 6 h, catalyst content 0.1%（on the mass of reactant）. Using the mixture solvent of V（chloroform）： V（methanol）= 25：1 as eluant, high purity of triesteramine, diesteramine and monoesteramine were isolated by column chro- matography, which were qualitatively analyzed by high performance liquid chromatography （HPLC）, infrared spectrum （IR） and mass spectrum （MS）.
