This thiol may have been used as a flavoring agent,〔(【引用サイトリンク】 tert-butyl mercaptan )〕 as an odorant for natural gas (which is odorless), and also in a wide range of organic reactions. ==Preparation== At least one publication has listed ''tert''-butylthiol as a very minor component of cooked potatoes, but because the ''tert''-butyl moiety is very rare in natural products, other sources doubt the existence of natural sources of the compound. 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tert-Butylthiol」の詳細全文を読む スポンサード リンク
