METHOD AND INTEGRATED PROCESS FOR THE CARBOXYLATION OF FURAN DERIVED CARBOXYLIC ACIDS TO 2,5-FURANDICARBOXYLIC ACID
摘要:
A process for carboxylation of a furoate slurry to produce FDCA, especially 2,5-FDCA, includes the steps of: feeding a slurry containing a suspension fluid, furoate, a surfactant and an alkali metal carbonate to a carboxylation reactor; and feeding a flow of CO

to the carboxylation reactor at flow conditions sufficient to suspend the slurry in the reactor and react the furoate with CO2 to form 2,5-FDCA. A fully integrated process is also disclosed.

A solution-processed organic electronic structural element has an improved electrode layer. Located between the active organic layer and the electrode layer there is either an interface or an interlayer containing a cesium salt.
Traditional inorganic scintillation crystals have a high stopping power to high-energy particles or rays, however, their wide applications are limited due to the fixed emission band. CsPbX3 (X = Cl,...
Abstract Using cesiumleadhalideperovskitenanocrystals, CsPb(Cl/Br)3, as a light absorber, we report a highly effective UV and blue light blocking film. The CsPb(Cl/Br)3 nanocrystals are well dispersed in the ethyl cellulose (EC) matrix to compose a UV and blue light shielding film, and the absorption edge of the film is tunable by adjusting Cl to Br ratio using anion exchange. The CsPbCl2Br-EC
