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.
Preparation
Difurfuryl disulfide is produced from Furfural and Hydrogen sulfide gas.
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.
