摘　　要：通过单因素实验法,研究了溶剂配比、溶解温度、溶解时间、加料量等因素对PA12溶解性能的影响。结果表明,用甲酸与乙酸作为复合溶剂,在95℃、冰乙酸∶甲酸=5∶13(V/V)、固液比为1∶12(g∶m L)、溶解时间3h时,所得溶解率最高,最高溶解率可达82%。实验证明,复合酸的协同效应对提高PA12溶解率至关重要。Solvent ratio,solution temperature,solution time and feeding quantity affecting on the dissolution properties of PA12 were investigated by single factor experiment method.The results showed that formic with acetic acid as compound solvent is used at temperature of 95 ℃,the scale of 5/13(volume ratio),solid-liquid ratio of 1∶ 12(g: mL) and the dissolution time of 3 h,the highest dissolution rate could be achieved 82%.The acid compound synergistic effect is very important to enhance the dissolution rate of PA12.
