Furfural production from biomass pretreatment hydrolysate

Biomass hydrolysate from autohydrolysis pretreatment was used for furfural production considering it is in rich of xylose, xylo-oligomers, and other decomposition products from hemicellulose structure. By using the vapor-releasing reactor system, furfural was protected from degradation by separating it

FURFURAL HAZARD SUMMARY Furfural

Furfural is a colorless, oily liquid that turns reddish brown on exposure to light and air. It is used in making chemicals, as a solvent in petroleum refining, a fungicide, and a weed killer. REASON FOR CITATION * Furfural is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, HHAG, NFPA, and EPA.
