laser surveillance

Using a laser monitoring observation technique, the solubilities of terephthalaldehydic acid, p-toluic acid, benzoic acid, terephthalic acid and isophthalic acid in N,N-dimethylformamide are measured by the synthetic method in this paper.

采用激光监视技术由合成法实验测定了对羧基苯甲醛、对甲基苯甲酸、苯甲酸、对苯二甲酸和间苯二甲酸在N,N-二甲基甲酰胺中的溶解度。

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.
