Organische Derivate des Silikagels mit SiOC‐Bindung I

Abstract: Methoden der organischen Chemie sind bisher kaum zur Konstitutionsaufklarung von Silikaten venvendet worden. Eincrseits sollten sich durch Umsetzungen an den aktiven Gruppen der Silikatoberflachen organische Derivate gewinnen lassen. Anderseits sollten sich die Silikate zu siliziumorganischen Vcrbindungen abbauen lassen.I n einer Reihe von Arbeiten wurde iiber die Herstellung und den Abbau organischer Derivate des Tonminerals Montmorillonit berichtet2). Dieses Mineral schien wegen seiner grossen aktiven Oberfl… Show more

“…g) Miscellaneous methods of attaching functional groups to silica Other more straightforward methods of attaching organic groups to the silica surface comprise the acetylation (or acylation) with acetyl chloride or other acyl chlorides [583,699], acetic anhydride [583,699,700], or even free carboxylic acids [699,700]. Isocyanates are also well suited for the binding of organic groups [249,701] S}-OH + OCN -Et ---S~-O-CO-NH-Et…”
