- Method of selectively catalytically oxidizing biomass-based furan compound
-
The invention discloses a method of selectively catalytically oxidizing a biomass-based furan compound. The method comprises the following step of: by taking a heteropolyacid functional ionic liquid as a catalyst and an alcohol solution as a reaction medium, obtaining dicarboxylic acid or dicarboxylate in the conditions that the reaction temperature is 100-150 DEG C, the reaction time is 1-3h and the oxygen pressure is 0.5-1.0MPa, wherein over 62.35% of difumarate selectivity is obtained. The single chemical yield and selectivity for oxidizing preparation of a biomass-based furan derivative are far higher than those of the prior art. The method has the remarkable advantage that an ionic liquid catalyst can be recovered and recycled by simply adjusting the temperature. The method disclosed by the invention is mild in reaction condition, green and safe in process and simple to operate, and can realize intermittent and continuous production.

- STABILITE THERMIQUE ET ALCOOLYSE DE QUELQUES YLURES DE TYPE
-
The thermal stability and alcoholysis reaction concerning ylides of the type X3P = is reported.These ylides undergo an addition reaction with methanol leading apparently to a pentacoordinated species which decomposes with or without breaking of the P-C bond.
