摘要
利用植物油环氧化制备增塑剂,由于其绿色无毒而备受关注。本文利用地沟油为原料,通过过氧甲酸法制备环氧地沟油,探讨地沟油高值化利用的新途径。实验以硫酸为催化剂,双氧水为供氧剂,甲酸为受氧剂,对地沟油环氧化反应条件进行了研究;通过单因素实验和L25(54)正交实验确定了最优反应条件:100g地沟油中加入67g双氧水-浓硫酸(双氧水:浓硫酸的质量比为200:1),10g甲酸在70℃下恒温搅拌反应6h,最佳反应条件下产物的环氧值达到了5.26%,碘值为3.67g/100g,酸值(KOH)为0.48mg/g。本工艺简单,原料成本低廉,产品性能完全可以满足增塑剂的要求。
The epoxidized plant oil used as plasticizer is non-toxic and has attracted more attention.In this article,the epoxidized drainage oil was prepared by peroxy formic acid method.The optimal conditions were obtained by orthogonal experiments as follows：the hydrogen peroxide and sulfuric acid（mass ratio：200∶1）is 67 g and formic acid is 10 g per 100 g drainage oil;reaction temperature is 70 ℃ and reaction time is 6 h.Under these conditions,the epoxy value of the final product is 5.26%.The iodine value is 3.67 g/100 g and acid value（KOH） is 0.48 mg/g.The low-cost products prepared by this method could meet the requirements of plasticizer.
