Furfuryl mercaptan has a characteristic unpleasant odor. It is prepared by reacting thiourea and furfuryl chloride with subsequent hydrolysis of the reaction product; also by reduction of difurfuryl disulfide in alcoholic solution using zinc dust and a small amount of acetic acid or using activated alumina. Furfuryl mercaptan tends to polymerize when heated in the presence of mineral acids.
