癸二酸二辛酯

癸二酸二辛酯用途

1.用途用作硝酸纤维素、聚氯乙烯树脂的耐寒增塑剂，且耐挥发性、光稳定性、电绝缘性、润透性能好。还可用作多种合成橡胶、乙基纤维素、聚甲基丙烯酸甲酯、聚苯乙烯、氯乙烯乙酸乙烯酯共聚物等的增塑剂。在航空工业上可作喷气发动机的润滑油和润滑脂。主要用于聚氯乙烯电缆料、薄膜、人造革等制品。也可用于制造润滑油、精密机械油溶剂和合成橡胶软化剂。

2.为典型的耐寒性增塑剂，适用于聚氯乙烯、氯乙烯醋酸乙烯共聚物、聚甲基丙烯酸甲酯、硝酸纤维素、乙基纤维素和合成橡胶等。其增塑效率高，挥发性低，既具有优良的耐寒性，又有较好的耐热性、耐光性和电绝缘性，而且加热时具有良好的润滑性，使制品外观、手感良好，特别适用于制作耐寒电线电缆料、人造革、薄膜及胶黏剂等。但该品迁移性较大，易被烃类抽出，耐水性也不太理想，常与邻苯二甲酸酯类并用。美国FDA许可DOS增塑的塑料薄膜用于食品包装材料。

癸二酸二辛酯制备

1.癸二酸和辛醇（质量比1∶1.6）在硫酸（癸二酸和辛醇总质量的0.25%）的催化下进行酯化反应，先生成单辛酯，这步酯化较为容易。第二步生成双酯，较为困难。要控制较高的温度，约130～140℃，0.093MPa真空度下进行脱水，反应时间3～5h，才可获得高收率。粗酯用2%～5%的纯碱水溶液中和，然后在70～80℃下水洗，再于0.096～0.097MPa的真空度下脱醇，当粗酯闪点达到205℃时即为终点。粗酯经压滤即得成品。

精制方法：减压精馏法。

2.氧化亚锡催化法　在装有温度计、回流分水器、搅拌器的200mL四口烧瓶中，加入计量好的癸二酸、辛醇（过量15%）及0.05%的催化剂氧化亚锡，在氮气保护下，控制一定的反应温度（200～230℃）进行酯化反应，用分水器收集被辛醇带出的水，辛醇回流至反应瓶中继续参加反应。水放入一量筒中，当量筒中的水达一定量时，取样滴定其酸值，若小于0.2mgKOH/g时视为反应完成，否则继续反应直至合格。将反应液冷却至90℃，加碱水进行中和水洗，静置分层，放出碱水后，进行减压蒸馏除去物料中未反应的辛醇，最后加活性炭吸附过滤即得产品DOS。
