|Section2= |Section3= }} Tripropylene, also known as propylene trimer, is a mixture of organic compounds with the formula C9H18.〔(Tripropylene MSDS ), chemexper.net〕 This mixture is obtained by oligomerization of propene: :C3H6 → C9H18 In this process, two double bonds are lost and one is retained as illustrated by the isomer shown in the figure. The reaction is catalyzed by acids, such as polyphosphoric acid.〔G. R. Lappin, L. H. Nemec, J. D. Sauer, J. D. Wagner "Olefins, Higher" in Kirk-Othmer Encyclopedia of Chemical Technology, 2010. 〕 A variety of catalysts have been explored.〔Johan A. Martens, Wim H. Verrelst, Georges M. Mathys, Stephen H. Brown, Pierre A. Jacobs "Tailored Catalytic Propene Trimerization over Acidic Zeolites with Tubular Pores" Angewandte Chemie International Edition Angewandte Chemie International Edition 2005, Volume 44, Issue 35, pages 5687–5690. 〕 The reaction proceeds via the formation of a carbocation ((CH3)2CH+), which attacks another propylene unit, generating a new carbocation, etc. This kind of process affords mixtures (C3H6)n. Like other alkenes, propylene trimer is used as an alkylating agent. A number of surfactants and lubricants are produced by alkylation of aromatic substrates. == References == 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「Tripropylene」の詳細全文を読む スポンサード リンク
