    • This Invention relates to products and processes for making extreme-pressure additives (water-dispersible and oil-based). The process includes nitrating fatty raw material sources such as animal fats, vegetable oils, the fatty acids and synthetic esters derived therefrom, terminal or internal olefins, polyalkenes or their linear copolymers, and alkylated phenols, using 70% nitric acid or nitrogen dioxide gas. The additives are used as soluble oils or as lubricating blends by the inclusion of emulsifiers. The nitrated unsaturated fatty acids such as tallow fatty acid, oleic acid, tall oil fatty acid, tall-oil derived dimer acids, castor oil fatty acid, alkyl succinic acids, are modified by post-reaction to form alkanolamine (monoethanolamine, triethanolamine) salts or alkanolamides in order to obtain the derived water-dispersible nitro-EP additives. The same nitration method is used to make ethoxylated fatty esters by reaction with water-soluble polyglycols in order to obtain water-dispersible nitro-EP additives.
    • 本发明涉及制备极压添加剂(水分散性和油性)的产品和方法。 该方法包括使用70%的硝酸或二氧化氮来对脂肪原料来源如动物脂肪,植物油,脂肪酸和由其衍生的合成酯,末端烯烃或内烯烃,聚烯烃或其线性共聚物和烷基化酚进行硝化。 添加剂通过包含乳化剂用作可溶性油或作为润滑共混物。 通过后反应改性硝酸不饱和脂肪酸如牛油脂肪酸,油酸,妥尔油脂肪酸,妥尔油衍生的二聚酸,蓖麻油脂肪酸,烷基琥珀酸,形成链烷醇胺(单乙醇胺,三乙醇胺)盐 或链烷醇酰胺,以获得衍生的水分散性硝基-EP添加剂。 使用相同的硝化方法通过与水溶性聚二醇反应制备乙氧基化脂肪酯,以获得水分散性硝基-EP添加剂。
