| 摘 要： | 菜籽油是一种非常有潜力的矿物润滑油替代产品,但菜籽油中含有大量双键,导致其氧化稳定性差,难以达到常规润滑油的性能标准.以强酸性阳离子树脂为催化剂,采用无溶剂法合成环氧菜籽油.通过正交试验对环氧化反应条件进行优化.试验结果表明:环氧菜籽油具有较低的碘值,较高的粘度指数,再加入一定量的添加剂后.其氧化诱导时间大于80 h,凝点达到-28℃.

| Abstract: | Rapeseed oil is a kind of promising substitute of fossil lubricants,but it contains a lot of double bonds,which result in poor oxidation stability for rapeseed oil,so it difficult to meet the requirements of modern lubricants.In this paper,using solvent-free method,and with strong acid cation exchange resin as the catalyst to synthesis the epoxidized rapeseed oil,and the condition of epoxidation was optimized by orthogonal experiment.The results showed that:epoxy oil has a low iodine value and a high viscos... |
