制备方法与用途

理化性质

2-乙基己酸锌又称异辛酸锌、亚辛酸锌，是一种淡黄色均匀透明的液体。其密度为1.17 g/cm³。与传统环烷酸锌相比，异辛酸锌具有色泽浅、气味小及含量高的特点。

用途与作用

本产品广泛应用于聚氨酯涂料及弹性体作为催化剂，能促进脂肪族异氰酸酯的交联反应，缩短固化时间。此外，它还用作PVC塑料热稳定剂。

另外，2-乙基己酸锌也是涂料中优秀的润湿剂和分散剂，可应用于悬浮剂、消光剂、船底漆防污剂等；在油墨中作为胶凝剂；用于油品添加剂；防腐、防霉剂等领域。

沉淀法制备异辛酸锌

沉淀法是通过皂化反应与复分解反应制备异辛酸锌。具体步骤如下：

1. 第一步：生成钠皂
   将氢氧化钠和异辛酸混合，进行皂化反应生成异辛酸钠（RCOO Na），反应方程式为： [ RCOOH + NaOH = RCOONa + H_2O ] 其中 (R) 代表 CH₃(CH₂)₃CH(C₂H₅)。

2. 第二步：生成异辛酸锌
   使用硫酸锌溶液置换钠皂，生成异辛酸锌。反应方程式如下： [ 2RCOONa + ZnSO_4 = Zn(RCOO)_2 + Na_2SO_4 ] 其中 (R) 同上。

合成步骤：

1. 在反应器中加入一定量的异辛酸和氢氧化钠溶液，搅拌升温至一定温度进行皂化反应。
2. 加入适量矿物油和硫酸锌溶液，在充分搅拌下进行反应。
3. 反应完全后，静置分层，分离出下层水相，并用热水清洗上层油层2～3次。分析洗液中锌的含量。
4. 上层油相经减压蒸馏脱水即可得到异辛酸锌产品。测定其锌的含量以计算相应产品的收率。

毒性及卫生性

2-乙基己酸锌对皮肤和黏膜有刺激作用。根据GB 9685-2008的规定，最大使用量分别为塑料PE、PP中为1.0%；PS中为0.1%；在黏合剂、纸中的用量按生产需要适量使用；特定迁移量（以锌计）不大于25.0 mg/kg。

用途

主要用作涂料催干剂，尤其是在白漆中表现出更好的特性。
