摘　　要：以荧光增白剂CBW为主要原料,经过酸化改性,再用有机胺中和,并添加助溶剂聚乙二醇400以及适当的稳定剂,络合剂,制得有效成分含量高达20%以上的液体增白剂CBW-20L.该产品质量稳定,耐氯、耐碱、耐硬水效果好,应用于液体洗涤剂中可使洗涤剂的去污值及综合去污指数提升显著.By applying fluorescent brightening agent CBW as the main raw material, polyethylene glycol 400 as cosolvent,proper stabilizer and complexing agent, liquid fluorescent brightening agent CBW20L is prepared. It has 20 wt% active ingredientafter acid treated and organic amine neutralized. The product has excellent stability and superior chlorine, alkali and hard waterresistance. Detergency value and comprehensive decontamination index of the liquid detergent are remarkably improved after addingthe liquid detergent CBW20L.
