摘　　要：采用碱法从铬鞣废革屑中提取胶原蛋白,然后对其进行羧甲基化、酰氯化改性和金属离子沉淀得到胶原蛋白凝油剂,探讨了羧甲基化、酰氯化程度和金属离子种类对制备反应的影响,确定了制备条件为:羧甲基化时,氯乙酸钠与纯胶原蛋白质量比为1:3:1;酰氯化时,油酰氯与胶原蛋白质量比为3:1;金属离子沉淀时,铝盐的沉淀效果最好。采用红外光谱分析对制得的凝油剂进行结构表征。模拟凝油试验结果表明,制备的凝油剂的凝油效果良好。The collagen was extracted from chrome shavings with alkali. Through the carboxyl methylation, acylation and deposition with metal ions, the oil gelling agent was obtained. Moreover, the influence of carboxy methylated degree, acylated degree and the categories of metal ions on preparation reaction was discussed. The better preparation condition was obtained. In carboxyl methylation the weight ratio of sodium chloroacetate and collagen was 1.3 collagen was 3 ： 1 ; in deposition with metal ions the effect of aluminium ： 1 ; in acylation the weight ratio of oleoyl chloride and is best. The structural characterization of prepared oil gelling agent was carried out by IR spectrum. And the results show its oil gelling effect is good.
