摘　　要：酰胺化羊毛脂采用P2O5分散投料,缓释法合成磷酸化改性羊毛脂皮革加脂剂。确定了磷酸化反应的较佳条件为:羟基与P2O5的摩尔比为3 0∶1 0,75℃,反应2 5h。结果表明:与P2O5直接投料反应相比,缓释法合成的产物中单酯(MAP)摩尔分数x(MAP)提高了12 3%,P2O5的反应转化率提高了5 7%。Leather fatliquor made of phosphonation modified lanolin was prepared using amidated lanolin and dispersed P_2O_5 as starting material by controlled release method.Optimal phosphonation conditions are:ratio OH/P_2O_5(molar)=3.0∶1.0,at 75 ℃ for 2.5 h.Experimental results showed that the monophosphate content in the product is 12.3 %(molar basis)higher than that obtained using direct phosphonation method,while the yield increases for 5.7 %.The original bad odor of the lanolin is eliminated and is good for application.There is no waste effluent generated from the process.
