硬脂酸镉制备方法及用途

制备方法

(1)硬脂酸钠溶液制备将硬脂酸溶解于20倍(质量)的热水中,加入含量为1074kg/m3(10°Bé)的烧碱溶液,于75℃左右进行皂化反应,生成稀的硬脂酸钠溶液。 (2)硫酸镉溶液制备将金属镉溶解于硫酸和硝酸中,制得硫酸镉溶液。 (3)硬脂酸镉的制备将硫酸镉溶液加入到硬脂酸钠溶液中,于55℃左右进行复分解反应,产物硬脂酸镉以沉淀析出。经过滤、水洗,于70～75℃下干燥,即得成品。 4.将等摩尔量的硬脂酸和醋酸镉粉末混匀后,在117～118℃下加热,蒸出乙酸和结晶水后,就得到定量的硬脂酸镉。本反应也可在过量的乙酸溶液中进行。 5.将15g硬脂酸钠溶在1L热水中,得到清澈的溶液,趁热将此溶液加入过量的1%氯化镉或硫酸镉的溶液中,一边加一边强力搅拌,待析出絮状的硬脂酸镉沉淀后,用倾泻法彻底洗涤,直到无游离的可溶性镉盐存在为止。置空气浴中在115～120℃下干燥10～12h。冷却后得到硬脂酸镉产品,粉碎后置密封瓶中保存。

用途简介

本品用作聚氯乙烯的热稳定剂和润滑剂。具有优良的透明性、光稳定性、耐水性和电绝缘性,初期着色性极小,热稳定效能高,制品的耐候性好。本品可单独使用,也可与钡皂、有机锡化合物、环氧化合物或亚磷酸酯并用,有显著的协同效应。本品常与钡皂、钡锌皂或钡铅皂并用于薄膜、薄片、人造革等软质制品。但本品的加工操作性不太好,加工温度低时,塑化不完全,温度过高时易焦化。在硬质制品中与铅类稳定剂配合可改善加工性。本品的一般用量为01%～1%。有受硫化物污染的缺点。用量大时易离析结垢。用作为润滑剂和塑料稳定剂。
