Abstract
Steam distillation, solvent extraction, and ion exchange procedures have been employed to isolate volatile organic acids, bases, and neutral compounds from process waters generated during the retorting of oil shale. Gas chromatography was used for the analysis of the isolated components and for the direct analysis of the process waters. The use of these multiple isolation and analyses procedures has resulted in the determination of the following compounds with the amounts in ..mu..g/mL given in parentheses: 12C/sub 2/ to C/sub 10/ aliphatic acids (26 to 450); phenol (21); pyridine (5); five methyl substituted pyridines (3 to 19); aniline (2); isoquinoline (2); four C/sub 1/ to C/sub 4/ n-alkylamines (2 to 10); three C/sub 2/ to C/sub 4/ n-alkylnitriles (1 to 21); benzonitrile (3); formaldehyde (500); acetaldehyde (2); propanone (16); and butanone (6). The advantages of steam distillation and ion exchange for the isolation and eventual analysis for water containing complex mixtures of volatile acidic, basic, and neutral organic compounents are described.
