| 2-Methyl-2-propanethiol Usage And Synthesis |
| Description | tert-Butylthiol, also known as 2-methyl propane-2-thiol, 2- methyl-2-propane thiol, tert-butyl mercaptan (TBM), and t-BuSH, is an organo sulfur compound with the formula (CH3)3CSH. This thiol may have been used as a flavoring agent, as an odorant for natural gas (which is odorless), and also in a wide range of organic reactions. |
| Chemical Properties | liquid with an exceedingly unpleasant smell |
| Uses | 2-Methyl-2-propanethiol was used in reaction of 2-methyl-2-propanethiol on Mo(110) using temperature programmed reaction, high resolution electron enegy loss and X-ray photoelectron spectroscopies. It was used in the synthesis of chain-transfer agents for reversible addition-fragmentation chain-transfer copolymerization of vinylidene chloride and methyl acrylate. |
| Uses | Tert-Butylthiol is the main ingredient in many gas odorant blends. It is always utilized as a blend of other compounds, typically dimethyl sulfide, methyl ethyl sulfide, tetrahydrothiophene or other mercaptans (isopropyl mercaptan, sec-butyl mercaptan and/or n-butyl mercaptan, due to its rather high melting point of 273 K. These blends are used only with natural gas and not propane, as the boiling points of these blends and propane are quite different. As propane is delivered as a liquid and vaporizes to gas when being delivered to the appliance, the vapor liquid equilibrium would substantially reduce the amount of odorant blend in the vapor. Tert - Butyl thiol has been listed on the European Food Safety Authority (FL-no: 12.174) as a flavor additive. There is no indication of what flavor or flavors it may have been used in. It has been removed from this list. |
| Preparation | tert-Butyl thiol likely does not occur naturally, but at least one publication has listed it as a very minor component of cooked potatoes. The compound was first prepared in 1890 by Leonard Dobbin by the reaction of zinc sulfide and t-butyl chloride. The compound was later prepared in 1932 by the reaction of the Grignard reagent, t-BuMgCl, with sulfur to give the corresponding thiolate, followed by hydrolysis. This preparation is shown below: t-BuMgCl + S → t-BuSMgCl t-BuSMgCl + H2O → t-BuSH + Mg(OH)Cl It is currently prepared industrially by the reaction of isobutylene with hydrogen sulfide over a clay (silica alumina) catalyst. |
