摘要
将生活污油回收处理并用活性白土脱色,利用回收油脂和松香制得洗衣皂。考察了碱液用量、Na OH质量分数、皂化时间和温度对皂化度的影响。结果表明,在较佳工艺条件下,皂化度可达98.4%,制得的洗衣皂符合行业标准。
The life waste oil was treated and bleached by actived bleaching earths. A kind of laundry bar soap was made using the recyded oil and rosin. Effects of the mass fraction of NaOH, dosage of lye, reaction time and temperature on the degree of saponification were investigated. Results indicated that the degree of saponification was 98.4% on optimum conditions and product met the requirements of industrial standard. The preparation process was very simple and the cost was low. This study was meaningful for social development, environmental protection and economic sustainability.
