Abstract : Recently enacted air pollution abatement laws regulate the amount of photochemically reactive solvents that can be used in paint products. Aromatic solvents possess the strongest solvency of the hydrocarbon types, but their use in paint must now be restricted in order to comply with air contamination laws. This report describes a suitable gas chromatographic procedure for the determination of toluene, ethyl benzene and total aromatics in enamels and thinners. The solvent is isolated by vacuum distillation. High boiling and low boiling internal standards are added and the analysis is conducted on six and eighteen foot columns containing N,N-Bis(2-cyanoethyl) formamide as the liquid. (Author)
