Dibutyl sulfide Chemical Properties,Usage,Production

Description

Dibutyl sulfide (also named as butyl sulfide; N-butyl sulfide; Di-n-butyl sulfide; butylthiobutane), a colorless to pale yellow clear liquid, is a symmetric thioether. Dibutyl sulfide is found in raw cabbage, boiled and cooked beef, and some varieties of mushroom.
Dibutyl sulfide is typically used as a flavoring agent. As a thioether, dibutyl sulfide has applications in organic synthesis as a solvent as well as a reagent. It is used to synthesize specific compound classes including property-enhancing additives, pharmacological drugs, chemical resistant polymers, detergents, and rubber antioxidants. Dibutyl sulfide can also be used as an agricultural intermediate, a sulfiding agent, a refinery catalyst, a lubricant additive, a gas odorant, and a processing aid in mining applications. Furthermore, it can be used as an internal standard in X-ray fluorescence spectrometry (XRF) measurements of sulfur in oils and other liquid hydrocarbon matrices.

Chemical Properties

colourless liquid with a very unpleasant smell

Chemical Properties

Butyl sulfide has an herbaceous, green, garlic, onion, heavy odor.

Occurrence

Reported found in raw cabbage, cooked beef and mushrooms.

Uses

Di-n-butyl sulfide is generally used as an agricultural intermediate, a sulfiding agent, a refinery catalyst, a lubricant additive, a gas odorant and a processing aid in mining applications. It finds application as an internal standard in X-ray fluorescence spectrometry (XRF) measurements of sulfur in oils and other liquid hydrocarbon matrices.

Preparation

From butyl bromide and sodium sulfide in boiling ethanol; according to some authors two forms exist, exhibiting different boiling points but identical solubilities in various solvents; both forms are insoluble in water.

Definition

ChEBI: Dibutyl sulfide is an aliphatic sulfide.
