摘要:以松香、十二醇为原料,在无溶剂和氮气保护下,通过酯化反应合成了环保型增塑剂松否十二醇酯。在催
化剂的筛选及最佳反应温度确定的基础上,通过(3)正文实验详细研究了松香十二醇酯的合成工艺、确定了最住
反应条件,即松香中树脂酸与十二醇的物质的量之比为1:2.5,催化剂浓H2SO4用量为松香质量的5%,反应温度控
制在140~145℃,反应时间为8h。由此合成的产物产率为75.1%。然后通过傅立叶变换红外光谱、紫外一可见光谱
核磁共振氩谱、热重分析等手段对产物进行了表征和测试。结果表明,合成的产物即为目标产物松香十二醇酯,而其
主分解温度为295℃,可以作为具有一定耐温性能的环保型增塑剂来使用。

Abstract: Under the conditions of solvent-free and nitrogen protection, environmentally-friendly plasticizer rosin laury
alcohol ester was synthesized by esterification reaction with rosin and lauryl alcohol as raw materials and concentrated sulfuric acid
catalyst. On the basis of selecting proper catalyst and confirming suitable reaction temperature, the synthesis process of rosin
lauryl alcohol ester was studied by L,(3 orthogonal test in detail and the optimum reaction conditions were that the molar ratio of
resin acid in rosin and laury alcohol is 1: 25, the content of the catalyst concentrated sulfuric acid was 5% of the weight of the
rosin, reaction temperature was 140-145C, reaction time was 8 h. And the yield of the synthesis product was 75.1, Meanwhile
the synthesis product was characterized and tested by means of FTIR, Uv-vis, H NMR and TG. The results show that the target
product really is rosin lauryl alcohol ester, its main decomposition temperature is 295, so it can be used as an environmental fri-
endly plasticizer which has certain heart resistance
