摘要：

Differential scanning calorimetry (DSC) has been applied to 273 environmental standards, including pesticides, herbicides and related compounds. Members of the following chemical classes were analyzed: organophosphorus, organochlorine, phenol, triazine, uracil, phenoxy acid, urea, carboxylic acid, amide, and others including amines, organometallics, esters and heterocycles. Values for the heat of fusion, experimental temperature onset, theoretical temperature onset for 100% pure compound, and percent purity are presented. DSC was found to be a widely applicable method to most classes of organic environmental standards and their metabolites. © 1990.
