It is produced industrially as an intermediate to 3-methylbut-2-en-1-ol (prenol): global production in 2001 can be estimated as 6–13 thousand tons.〔. Major produce in a world is BASF(Germany) and Kuraray(Japan).〕 Isoprenol is produced by the reaction between isobutene (2-methylpropene) and formaldehyde. The thermodynamically preferred isomer with the more substituted double bond cannot be directly formed in this reaction, but isomerization yields the desired product: The reaction is catalyzed by any species which can form an allyl complex without excessive hydrogenation of the substrate, for example poisoned palladium catalysts.〔See, e.g., .〕 ==Notes== 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「isoprenol」の詳細全文を読む スポンサード リンク
