红油(美国助磨剂商品名,化学成分为脂肪酸混合物CAS：112-80-1分子式：C18H34O2分子质量：282.46沸点：360℃熔点：13.4-222℃中文名称：油酸；(Z)-9-十八烯酸；顺-9-十八烯酸；十八烯酸；红油；顺式-9-十八烯酸；顺式十八碳-9-烯酸；顺-9-十八烯酸；红油(美国助磨剂商品名,化学成分为脂肪酸混合物英文名称：Oleic acid；9-Octadecenoic acid (Z)-；(z)-9-octadecenoic aci；(z)-9-octadecenoic acid；9,10-octadecenoic acid性状描述：纯品为无色透明液体，在空气中颜色逐渐变深。工业品为黄色到红色油状液体，有猪油气味。熔点：α-型13.4℃；β-型16.3℃，沸点223℃（1.333kPa），286℃（13.3kPa），相对密度0.8905（20/4℃），折射率1.4582，闪点372℃。溶于酒精；苯和氯仿等有机溶剂，不溶于水。由于含有双键，在空气中长期放置能发生自氧化，出现腐败的哈喇味。油酸与硝酸作用则异构化为其反式异构体，熔点为45-45.5℃的反油酸。生产方法：油酸与其他脂肪酸一起，以甘油酯的形式存在于一切动植物油脂中。在动物脂肪中，油酸在脂肪酸中约占40-50%。植物油中的含量变化较大，茶油中可高达83%，花生油中达54%，而椰子油中则只有5-6%。油酸为生产硬脂酸时的联产品，工业硬脂酸和工业油酸实际上都含有其他脂肪酸。用于生产硬脂酸和油酸的油脂原料很多，工业上一般取混合油脂配方，例如熔制牛脂30%；熔制猪脂10%；骨脂40%和棉籽油20%。油脂经精制；水解得到的混合脂肪酸中，饱和酸与不饱和酸熔点差异较大。硬脂酸和油酸的收率主要决定于油酯配方，一般情况下，冷榨可以得到30-50%油酸，50-70%硬脂酸。以动植物油脂和乳化液于105℃下水解，用硬脂酸净化，经一次压榨除去硬脂酸，分离得粗油酸，经脱水；蒸馏；冷冻。再经二次压榨，除去软脂酸，最后经脱水精制而得成品。本法可联产硬脂酸，同样由油酸制硬脂酸时，也会联产油酸。 原料消耗定额：动植物油脂1950kg/t；硫酸（98%）210kg/t。用途：油酸是有机化工原料，经环氧化可生产环氧油酸酯，用作塑料增塑剂，经氧化可生产壬二酸，是聚酰胺树脂的原料。此外，油酸还可作为农药乳化剂；印染助剂；工业溶剂；金属矿物浮选剂；脱模剂等，也可作为复写纸；圆珠毛油和打字蜡纸生产的原料。各种油酸盐产品也是油酸的重要衍生产品。作为化学试剂，用作色谱对比样品及用于生化研究，检测钙；铜以及镁；硫等元素。
