| 中文摘要 |
| 铬革渣在碱性介质中脱鞣提取蛋白质的过程中,当反应体系的pH=13,反应压力为1.4kg/cm2,11h后出现蛋白质水解产物氨基酸,随反应时间的延长,水解度随之增大.这种水解,随体系的pH值升高而加快.实验表明,用改进的甲醛滴定法可测定铬革渣在碱性介质中蛋白质的水解度. |
| 英文摘要 |
| In the process of extracting protein by the dechroming of chrome leather scrap in basic medium,contributed to the hydrolysis of protein,amino acids appear in 11 h when the pH value is 13,and the reaction pressure is 1.4kg/cm2.The hydrolysis degree of protein increases as the reaction is proceeding and it also increases when the pH value is raised.The experiments demonstrate that,in a basic medium, the hydrolysis degree of chrome leather scrap can be determined with a modified formaldehyde titration method. |
