Abstract:
Verfahren zur Herstellung von Vinylalkylenglykolethern mit den Schritten: (i) Bereitstellung von einem oder mehreren gegebenenfalls substituierten Phenylalkylenglykolethern der allgemeinen Formel (I),
worin R 1 Cl oder NO 2 und R 2 und R 2' unabhängig voneinander H oder C 1 -C 3 -Alkyl bedeuten und n = 1 bis 155 ist, (ii) Eliminierung von gegebenenfalls substituiertem Phenol aus dem oder den Phenylalkylenglykolethern der allgemeinen Formel (I) in Gegenwart einer Base, wobei ein oder mehrere Vinyalkylenglykolether der allgemeinen Formel (II)
worin R 2 , R 2' und n die oben angegebene Bedeutung haben, erhalten werden.
Abstract:
The invention relates to a method for producing glucose from cellulose material, in which a starting material containing cellulose is treated with a liquid treatment medium that comprises an ionic liquid, anions are selected therefrom using polyatomic anions, and the material containing cellulose and which is treated with ionic liquid undergoes enzymatic hydrolysis.
Abstract:
The present invention relates to a liquid composition which comprises at least one polymer and at least one ionic liquid, the cations of which are derived from polycyclic amidine bases, and a process for isolating cellulose from cellulose-containing sources using at least one such ionic liquid.
Abstract:
The present invention describes a method for producing acetals of poly-, oligo- or disaccharides by dissolving them in at least one ionic liquid and then reacting them with a vinylether. The resulting acetalized poly- or oligosaccharides can be cross-linked by treatment with acid. The present invention relates also to acetals of poly-, oligo- or disaccharides and cross-linked poly- or oligosaccharides.
Abstract:
The invention relates to a method for breaking down cellulose by dissolving the cellulose in an ionic liquid and treating it at elevated temperatures, optionally in the presence of water.
