由含铬下脚料和猪油制备蛋白型加脂剂

摘要

含铬下脚料在NaOH溶液中加热水解，得到的多肽与环氧化猪油反应，制得两亲型产物。初步应用表明该产品具有良好的加脂和助染功能。对产物进行了 IR表征，测试了其乳液的稳定性，用偏光显微镜观察了乳胶粒子大小。%Collagen hydrolysate was obtained from the hydrolysis of chromed trimmings and shayings acatalyzed with sodiumhydroxide. It reacted with epoxy lard to get an amphiphilic Preduct The molecule smucture was confirmecd by IR spectra. The emulsifying stability and article siae were tested. Preliminary application has tested that it is a good fatliauor with Properties of dry washing iresistanee and dyeing assistam.
