【摘要】 当非等物质的量比n(醇):n(酸)=1.1:1时、自催化的己二酸／新戊二醇、已二酸／2,2,4-三甲基-1,3- 戊二醇缩聚反应级数不是定值,而是与反应温度有关。低温时反应级数为2.5,高温时反应级数为3.0。更多还原

【Abstract】 Polyesterification kinetics of Adipic acid/NPG and Adipic acid/TMPD were investigated. It was found that the reaction order of self-catalyzed polyesterification is not a constant, but a function of temperature. The order of self-catalyzed polyesterification is 2. 5 in low temperatures, while 3 in high temperatures.更多还原
