摘要
为了回收、提纯PTA氧化残渣中的苯甲酸 ,采用激光监视技术由合成法测定了鲜见文献报道的苯甲酸在氯仿、N ,N -二甲基甲酰胺、N ,N -二甲基乙酰胺、N -甲基吡咯烷酮中的溶解度 .为了验证测定方法的可靠性 ,事先测定了苯甲酸在水、醋酸中的溶解度 ,与已有文献数据相比 ,一致性较好 .用Apelblat等人提出的溶解度模型对实验数据进行关联 ,计算的溶解度与实验值符合良好 .
Using a laser monitoring observation technique, the solubilities of benzoic acid in trichloromethane, N,N-dimethylformamide, N,N-dimethylacetamide and N-Methyl-2-pyrrolidonewere, which has never been seen in literatures before, are determined by the synthetic method. To verify the reliability of the experimental method, the solubility of benzoic acid in water was measured before the experiments, which shows excellent consistency with the literature data. By means of Apelblat's solubility model to correlate the experimental results, the calculated solubilities show good agreement with the experimental values.
