配方简单的高效稠油垢微碱性水基清洗剂的研制

基于绿色化学的基本理念,在不添加任何酸碱的条件下有机复配适当的表面活性剂和乳化剂,成功地研制出配方非常简单、对稠油垢去除效果优异的微碱性水基清洗剂。通过正交试验和配方优化实验,确定较佳的清洗剂配方组成为:8.0%烷基糖苷、3.5%脂肪醇聚氧乙烯醚、3.5%壬基酚聚氧乙烯醚和2.0%椰子油脂肪酸二乙醇酰胺,余量为自来水。该清洗剂的pH≈7.5,去污力高达99.3%,并且其原液、2倍稀释液和4倍稀释液的去污力明显优于相应条件下的市售清洗剂。所制备的微碱性水基清洗剂具有所采用的工业原料廉价、配方简单和去污性能优异等优点,因而具有广阔的应用前景。

Development of water-based cleaning agent for heavy oil foulant with simple formula,alkalescenceand high detergency

Based on the basic idea of Green Chemistry, a water-based cleaning agent with very simple formula, alkalescence and high detergency was successfully developed via organic built-up of appropriate surfactants and emulsifier without addition of any acid and base. Based on orthogonal experiments and formula optimization experiments, the optimal recipe was decided as follows:8.0% alkyl polyglucoside, 3.5% fatty alcohol-polyoxyethylene ether, 3.5% polyoxyethylene nonyl phenol ethers and 2.0% coconut oil glycolamide in a tap water solution. The cleaning agent has a nearly neutral pH of 7.5 and very high decontamination rate of 99.3%. The cleaning agent and its diluent solutions for 2 and 4 times have higher decontamination rate than that of the commercial multi-purpose cleaning agent and their corresponding diluent solutions. The cleaning agent has the advantages of cheap industrial raw materials, very simple recipe, excellent cleaning performance, and thus has widespread application prospect.
