Difurfuryldisulfide Chemical Properties,Uses,Production

Chemical Properties

Pale yellowish oily liquid. Slightly soluble in water, soluble in alcohol and oils.

Occurrence

Reported found in beef (boiled, cooked) and coffee

Uses

Furfuryl disulfide has been used in the preparation of poly(disulfido-imide)s by Diels-Alder (DA) reaction with the various bismaleimides.

Definition

ChEBI: Bis(2-furanylmethyl) disulfide is a heteroarene.

Preparation

Difurfuryl disulfide is produced from Furfural and Hydrogen sulfide gas.

Taste threshold values

Taste characteristics at 20 ppm: roasted, sulfuraceous, alliaceous, green and meaty.

General Description

Difurfuryl disulfide is a sulfur-containing volatile compound mainly found in roasted coffee. It is also the main degradation product of furfuryl mercaptan under Fenton-type reaction conditions.
