Abstract: PURPOSE:To improve the yield of the titled compound in the thermal decomposition of oxyflavan, by removing the water-soluble component from the heat- decomposition reaction mixture, and subjecting the obtained oil-soluble by- product to thermal decomposition. CONSTITUTION:Oxyflavan: polyalkyl-2-(2,4-dihydroxyphenyl)-7-hydroxychromane is subjected to the thermal decomposition by cracking in binary liquid phases of by cracking distillation process. The water-soluble component composed mainly of resorcinol is removed from the reaction mixture, and the remaining oily phase mixture containing water-insoluble solvent is distilled to remove the water-soluble solvent, and then crystallized to remove the objective compound. The oil-soluble by-produce left after the removal of the objective compound is thermally decomposed preferably at 160-230 deg.C to convert the polymer of the objective compound, e.g. polyalkyl-2,7-dihydroxychromane, to the objective compound. The objective compound can be recovered directly from the thermal decomposition reaction product or by transferring the reaction product to the above distillation process or crystallization process.
