Waste fried oil was studied to prepare three different types of detergent such as soap, liquid soap and soap powder via saponification process. The preparation conditions of soap base were optimized by orthogonal experiment. The specific preparation processes included waste fried oil treatment, orange peel extract preparation, saponification, demoulding and drying. Results showed that the optimal conditions for saponification were as follows: ratio of pure waste fried oil to coconut oil = 6:4, alkali liquor (NaOH) mass fraction 30%, saponification temperature 70 °C, orange peel extract concentration 15%. The mature soap was then used to make liquid soap and soap powder by surfactant (sodium dodecylbenzene sulfonate, coconut diethanol amide) addition, followed by grinding. The prepared detergent conforms to the production standard of strong decontamination ability, possesses stable performance, is gentle to skin and non-toxic.

一种废炸油绿色利用的新方法

【摘要】:以废油炸油为研究对象,通过皂化工艺制备了肥皂、皂液和皂粉三种不同类型的洗涤剂。通过正交试验优化皂基的制备条件。具体制备工艺包括废炸油处理、橙皮提取物制备、皂化、脱模和干燥。结果表明,皂化的最佳条件为:纯废炸油与椰子油的比例=6:4,碱液(NaOH)质量分数30%,皂化温度70℃,橙皮提取物浓度15%。熟皂经加入表面活性剂(十二烷基苯磺酸钠、椰油二乙醇胺)研磨制成皂液和皂粉。
