| 摘 要： | 提出了3 羟基丁酸乙酯本体聚合制备聚羟基丁酸酯(PHB)的工艺,设计了一套制备PHB的试验装置,确定了反应的试验方案。试验结果表明:在一定的反应时间范围内,随反应系统的压力降低及反应时间的延长,产物的摩尔质量逐步升高。还对化学法合成和生物发酵制备的PHB进行了生物降解性研究,确定了假单胞杆菌为降解PHB的主要菌类,化学合成的PHB可以被土壤中的细菌完全降解。

| Abstract: | A method to produce poly hydroxybutyrate(PHB) by bulk polymerization of 3-hydroxybutyrate was put forward.An experimental device was designed to produce PHB and the condition of reaction was confirmed.The results indicated the molecular weight of product increased gradually while the pressure decreased and the reaction time prolonged within the definite scope of reaction time.The biodegradations of PHB made by both chemical synthesis and fermentation were analyzed.Pseudomonas spp. was found to be the main microbe degrading PHB and the PHB synthesized chemically can be degraded completely by the microbe in soil. |
