摘　　要：用蒽酮分光光度法对 5种不同碳链APG的初级生物降解性进行了研究。结果表明 ,直链醇APG和碳链较短的支链醇APG能完全降解 ,但碳链为 1 4～ 1 5的支链醇APG不能被降解。探讨了结构对降解性的影响 :疏水基的结构对其降解性有较大影响 ,直链醇APG的降解性优于支链醇对APG的降解性 ,碳链较短的降解性优于碳链长的 ,链支化度影响支链醇APG的降解性 ;对其降解曲线的研究表明 :C8～ 1 0 直链、C1 4～ 1 5支链等APG的降解曲线存在降解度随时间下降的特殊现象 ;提出了APG一条可能的降解途径。Primary biodegradation experiment of APG with different chain length was carried out by anthrone spectrophotometer. Results showed that linear and short chain length branch APG could be degraded completely, while branch chain APG with 14～15 carbons could not. The hydrophobic groups have great effect on their biodegradability: linear APG has better biodegradability than branch APG, and short hydrocarbon chain better than long. Degradation curves of APG showed some degradation extent decreased with time.
