Isobutylmercaptan Usage And Synthesis
- Chemical PropertiesLiquid; unpleasant odor.
- Chemical Properties2-Methyl-1-propanethiol has a cooked vegetable, almost mustard-like, odor
- OccurrenceReported found in guava, milk, cooked beef, cooked pork and beer.
- UsesFlammable, dangerous fire risk.
- Purification MethodsDissolve the thiol in EtOH, and add to 0.25M Pb(OAc)2 in 50% aqueous EtOH. The precipitated lead mercaptide is filtered off, washed with a little EtOH, and impurities are removed from the molten salt by steam distillation. After cooling, dilute HCl is added dropwise to the residue, and the mercaptan is distilled directly from the flask. Water is separated from the distillate, and the mercaptan is dried (Na2CO3) and distilled under nitrogen.
