摘要
由硬脂酸和环氧乙烷聚合生成聚氧乙烯酯，然后，再与硬脂酸单甘酯复配得水溶性浆纱后上蜡。确定工艺条件：聚合反应温度为１２０±１０℃，压力为５８８～７８４ｋＰａ，时间为３ｈ，复配温度为８０～９０℃。产品收率为９８％以上，产品性能达到进口产品水平。该工艺适合中小型化工厂生产。
Polymerizing stearic acid with epoxy ethane,polyoxyethylene ester was synthesized ,then, it was composited with monostearin,thus,a waxapplied to the starching yarn was prepared.The determined process conditions were that, polymerization temperature,120±10℃;pressue,588～784 kPa:reaction period,3h; composition temperature,80～90℃,Yield of tlie produetwas above 98%,and properties of the product achieved quality level of imported one,The process was suitable for middle and small-sized plants.
