Method for the determination of benzene insolubles, asphaltenes, and oils in coal-derived liquids
Technical Report
·
OSTI ID:7261072
The details are presented of the method used for the solvent analysis of coal-derived liquids. The method is used to determine the benzene insoluble (unreacted or partially reacted coal), the benzene soluble-pentane insoluble (asphaltenes), and the benzene soluble-pentane soluble (oils) fractions of coal-derived liquids. Since the procedure described uses benzene and n-pentane as solvents to analyze coal-derived liquids, safety precautions must be observed carefully. Strict adherence to the described procedure is necessary to insure that the conditions of solvent treatment are uniform and to obtain the desired degree of precision.
