SOLVENT EXTRACTION STUDY OF A WHOLE, LOW-TEMPERATURE TAR

A LOW-TEMPERATURE TAR WAS SUB-DIVIDED, ENTIRELY BY SOLVENT EXTRACTION, INTO THE FOLLOWING FRACTIONS' CRUDE PHENOLS AND BASES, HYDROCARBONS OF DIFFERENT TYPES - ALIPHATIC, HYDROAROMATIC AND AROMATIC, AND A NEUTRAL, OXYGEN- CONTAINING AROMATIC FRACTION. THE THREE HYDROCARBON MATERIALS AND THE LAST-NAMED WERE OBTAINED FROM THE NEUTRAL TAR OIL / LIGHT PETROLEUM-SOLUBLE / BY A SERIES OF PARTITION EXTRACTIONS WITH THE SOLVENT PAIR, FURFURAL/LIGHT PETROLEUM, PETROLEUM, USING DEFINATE RATIOS OF TAR/SOLVENTS. THESE FOUR FRACTIONS CORRESPONDED CLOSELY TO THESE PREVIOUSLY OBTAINED BY ADSORPTION CHROMATOGRAPHY. /RRL/A/
