General description

Furfural is a furan derivative. It is a potential substitute for petroleum-based building blocks used in the production of fine chemicals and plastics. Production of furfural by dehydration of fructose, glucose and xylose using a biphasic reactor system has been reported. Furfural, a Maillard reaction product, is reported to inhibit the growth and alcohol production bySaccharomyces cerevisiae. Selective conversion of furfural in H2 over SiO2-supported Ni and Ni-Fe bimetallic catalyst has been reported. Furfurals are the are major components of bio-oil.

Application

Furfural may be used in the preparation of biofuel 2-methylfuran.
