摘　　要：本文研究了甲醇钠用量,酸化条件,水洗温度和结晶溶剂的种类等后处理因素对二苯甲酰甲烷酮式-烯醇式互变异构的影响,并对二苯甲酰甲烷的稳定性进行了分析。实验中发现烯醇式结构的含量与二苯甲酰甲烷的热稳定性的关系,对二苯甲酰甲烷作为高分子材料的辅助稳定剂的应用具有重要的意义.The influence of the after dealing with factors of the dosage of sodium methoxide, acidification conditions, temperature of water and the type of Crystal solvent on the keto-enol tautomerism of dibenzoylmethane is studied. The thermostability of dibenzoylmethane is analyzed. The relation between the content of enol structure and the thermostability of dibenzoylmethane has been found in the experiment, which is significant application in dibenzoylmethane as polymer material assisted stabilizer.
