Dibutyl sulfide Chemical Properties,Uses,Production
Chemical Properties
colourless liquid with a very unpleasant smell
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.
General Description
Butyl sulfide is a volatile sulfur compound that can be used as a flavoring agent.
Purification Methods
Wash the sulfide with aqueous 5% NaOH, then water. Dry with CaCl2 and distil it from sodium. [Beilstein 1 IV 1559.]
