摘要： 研究了C4、C6、C8、C10和C14等饱和脂肪醇与对苯二甲酸合成对苯二甲酸脂肪醇酯的方法,并对比了其结晶点、密度、闪点等物化性能。结果表明,C6及以下的脂肪醇在常压低温下很难与对苯二甲酸反应,而C8及以上的脂肪醇在催化下易与对苯二甲酸反应;且C4的对苯二甲酸二丁酯闪点只有180 ℃;C14醇和酯熔点(结晶点)分别达38和67℃,不便于生产操作和使用;而C8、C10与对苯二甲酸的酯化物介于液固交界处,且闪点不低于210℃,是合成对苯二甲酸酯类增塑剂的合适原料。

Abstract: The synthesis methods of aliphatic alcohol-based terephthalate were studied using terephthalic acid and saturated aliphatic alcohol (C4, C6, C8, C10 and C14) as raw materials. And the physicochemical properties such as crystallization points, densities, and the flash points et al. were contrasted. The results indicated that the reactions of aliphatic alcohols of C4 and C6 with terephthalic acid at ordinary pressure and low temperature were difficult, and the aliphatic alcohols of C8, C10 and C14 could easily react with terephthalic acid under catalysis. The flash point of butylene terephthalate (C4) was 180 ℃. The melting (crystallization) points of alcohol and ester (C14) were 38 ℃ and 67 ℃, respectively, but it was not convenient for the operation and use. While terephthalic esters of C8 and C10 aliphatic alcohols were between liquid-solid junction, and the flash points were not less than 210 ℃, they were suitable raw material for the synthesis of terephthalic acid esters plasticizer.

Key words: plasticizer, terephthalic acid, terephthalic, aliphatic alcohol
