Methylthioethane Usage And Synthesis

Chemical Properties

clear colorless liquid

Chemical Properties

Methyl ethyl sulfide has a cabbage-like odor.

Occurrence

Reported found in tomato, cooked chicken, beef and pork, rum, bourbon, whiskey, cocoa and coffee

Uses

Ethyl Methyl Sulfide is used as a corrosion inhibitor for zinc metal which finds wide applications like electrode material in batteries, sacrificial anodes and metallic coatings. It is used in mixtures designed to odorize natural gas and is made to by-pass injection system.

Aroma threshold values

Aroma characteristics at 0.1%: sulfurous, tomato and cabbage vegetative with dimethyl sulfide, meaty and metallic nuances.

Taste threshold values

Taste characteristics at 0.25 to 2 ppm: sulfurous, vegetative, dimethyl sulfide-like sweet corn notes, eggy, meaty and clam nuances

General Description

Microwave spectra of the trans isomer of ethyl methyl sulfide and its 10 isotopic species has been investigated. Chlorination of ethyl methyl sulfide with N-chlorosuccinimide and sulfuryl chloride has been reported.
