Preparation of Protein-Surfactant with Waste Wool

摘要：

During leather manufacture of sheepskin, abundant of waste wool is produced, which is valuable for its high protein content. After the pretreatment, the wool is hydrolyzed to be polypeptide under alkali conditions. The best process condition is that when the usage of NaOH is 12％ (base on the mass of chrome shavings), the amount H2O is 8 times of the wool, hydrolysis temperature is 100℃, and the reaction time is 2.5h, The extraction efficiency of the polypeptide is more than 85.3％; the mass ratio of polypeptide condensed liquor (base on the mass of amino acid)and oleoyl chloride is 1.5:1, the protein-anionic surfactant could be produced with condensed reaction. The appearance of the product is yellowish sticky liquor, the CMC is 0.5 g/L, and the surface activity is excellent.
