HPLC and phase transfer catalysis in the analysis of oxidation products of lignite liquids and model compounds. [Oxidizing agents: trifluoroperacetic acid, ruthenium tetraoxide, ceric ammonium nitrate, potassium permanganate]
The objective of these studies was to develop new methods for the analysis of the types and quantities of aryl groups and alkyl groups present in the alkylarenes and hydroarenes which are major constituents of the liquefaction products derived from lignite coals. A number of oxidation reactions of light oil hydrocarbon mixtures and model compounds were investigated using trifluoroperacetic acid, ruthenium tetraoxide, ceric ammonium nitrate and permanganates as oxidizing agents. In order to get high yield oxidation reactions, phase transfer catalysts were utilized in some of the reactions. Derivatization of the reaction products to give highly uv absorbing compounds facilitated the analysis of the products with high power liquid chromatography (HPLC).
