Abstract

See full text

A process for the production of furfural from a biphasic composition including furfural, an organic solvent and soluble organic debris. The said process includes subjecting the biphasic composition to a liquid-liquid separation step to provide an organic phase and an aqueous phase. The organic phase includes the organic solvent, a first portion of the furfural and a first portion of soluble organic debris. The aqueous phase includes a remainder portion of the furfural and a remainder portion of soluble organic debris. The organic phase is subjected to a distillation step to provide a furfural stream and an organic solvent stream including the organic solvent and the first portion of the soluble organic debris. The organic solvent stream is conveyed to an adsorption unit to adsorb a second portion of the soluble organic debris, forming an organic debris-depleted recycle stream.
