Procedure

Polar substances contained in the recovered main fraction were quantified by gas chromatography (GC-14A, Shimadzu Corp.). The amount of polar substances was taken to be the total amount of acetonylacetone, 3-methyl-2-cyclopetenone, benzaldehyde and acetophenone. The polar substance removal rate was determined based on the following formula 1. Removal rate (%)=Amount of reduction in polar substances (ppm)/Content of polar substances before purification (ppm)×100
