翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Bis(triethoxysilylpropyl)tetrasulfide ： ウィキペディア英語版 Bis(triethoxysilylpropyl)tetrasulfide Bis(triethoxysilylpropyl)tetrasulfide is an organosulfur compound with the formula S4()2 (Et = C2H5). The molecule consists of two trialkoxysilyl propyl groups linked with a polysulfide. It is often sold as a mixture with the trisulfide. The compound is a colorless viscous liquid that is soluble in ordinary organic solvents such as toluene. Commercial samples often are yellowish. The compound is added to rubber compositions that contain silica filler.〔Kohjiya, Shinzo; Ikeda, Yuko "Reinforcement of general-purpose grade rubbers by silica generated in situ" Rubber Chemistry and Technology 2000, volume 73, pages 534-550. http://dx.doi.org.proxy2.library.illinois.edu/10.5254/1.3547604〕〔Wolff, Siegfried "Chemical aspects of rubber reinforcement by fillers" Rubber Chemistry and Technology 1996, volume 69, pages 325-346.http://dx.doi.org.proxy2.library.illinois.edu/10.5254/1.3538376〕 ==Synthesis and reactivity== The compound was first prepared by the reaction of the 3-chloropropylalkoxysilane with sodium tetrasulfide:〔Thurn, Friedrich; Meyer-Simon, Eugen; Michel, Rudolf "Verfahren zur Herstellung von Organosiliziumverbindungen (Continuous manufacture of bis() tetrasulfide)" Ger. Offen. (1973), DE 2212239 A1 19731004.〕 :Na2S4 + 2 ClC3H6Si(OEt)3 → S4()2 + 2 NaCl Bis(triethoxysilylpropyl)tetrasulfide is a bifunctional molecule in that it contains two kinds of reactive functional groups. The tetrasulfide group is a polysulfide, which means that it consists of a chain of sulfur atoms. S-S bonds are susceptible to reduction (to thiols), attachment to metals (e.g., for protection against corrosion), and vulcanization. The triethoxysilyl groups are susceptible to hydrolysis, resulting in cross-linking via sol-gel condensation. In the usual application of Si-69, the hydrolyzed siloxy groups attach to silica particles and the polysufide groups link to the organic polymer. 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「Bis(triethoxysilylpropyl)tetrasulfide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
