2-Methylfuran, also known with the older name of sylvane, is a flammable, water-insoluble liquid[3] with a chocolate odor, found naturally in Myrtle and Dutch Lavender[4] used as a FEMA GRAS flavoring substance,[5] with the potential for use in alternative fuels.

Manufacture

2-Methylfuran is an article of commerce (chemical intermediate) and is normally manufactured by catalytic hydrogenolysis of furfural alcohol or via a hydrogenation-hydrogenolysis sequence from furfural in the vapor phase.[6]
