Chloroethane Chloroethane Chloroethane or monochloroethane, commonly known by its old name ethyl chloride, is a chemical compound with chemical formula , once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor. Chloroethane is produced by hydrochlorination of ethene: At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, or from ethane and chlorine, but these routes are no longer economical. Some chloroethane is generated as a byproduct of polyvinyl chloride production. Should demand for chloroethane continue to fall to the point where
Dimethyl disulfide the fuel gas. Dimethyl disulfide Dimethyl disulfide (DMDS) is an organic chemical compound with the molecular formula CHSSCH which is the simplest disulfide. It is a flammable liquid with an unpleasant, garlic-like odor. Dimethyl disulfide is a widespread natural odoriferous compound emitted from many sources such as bacteria, fungi, plants and animals. It is an oxidation product of methanthiol in air. Along with dimethyl sulfide and dimethyl trisulfide it has been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum ("Helicodiceros muscivorus"). These flies are attracted to the odor of fetid meat, they help pollinate
