Abstract:
A process for preparing solutions which comprise 5-hydroxymethylfurfural (HMF) and have reduced content of starting materials from the HMF synthesis or a reduced content of by-products of the HMF synthesis (called product solution hereinafter), characterized in that solutions comprising HMF starting materials or by-products of the HMF synthesis and an organic solvent having at least two ether groups (polyether for short) (called starting solution hereinafter) are treated with steam in an evaporator.
Abstract:
The present invention is directed to a method for coating a sheet-like cellulose containing material by applying a composition comprising at least one glucan (G), which has a β(beta)-1,3-glycosidically linked main chain and at least one side group having a βφβί8)- 1,6-glycosidic bond to the main chain, particularly Schizophyllan, and at least one solvent (S), particularly a ionic liquid, on the surface of the sheet-like material.
Abstract:
The present invention relates to porous metallic frameworks comprising at least one at least bidentate organic compound coordinated to at least one metal ion, wherein the at least one at least bidentate organic compound is derived from 2,5-furandicarboxylic acid or 2,5-thiophenedicarboxylic acid. The present invention further relates to shaped bodies comprising these frameworks, processes for producing them and their use, in particular for the storage and separation of gases.
Abstract:
Described is a method for processing cellulose-containing biomass with sulfuric acid and certain additives, especially for the pretreatment of cellulose-containing biomass prior to saccharification.
Abstract:
Described is a method for producing furfural from one or more substances selected from the group consisting of xylose, oligosaccharides comprising xylose units and polysaccharides comprising xylose units.
Abstract:
The invention relates to a method for producing hexamethylenediamine, wherein a) a muconic acid starting material is provided, which is selected from among muconic acid, esters of muconic acid, lactones of muconic acid, and mixtures thereof, b) the muconic acid starting material is subjected to a reaction with hydrogen in the presence of at least one hydrogenation catalyst in order to form 1,6-hexanediol, and c) the 1,6-hexanediol obtained in step b) is subjected to amination in the presence of an amination catalyst in order to obtain hexamethylenediamine. The invention further relates to hexamethylenediamine which can be produced by means of said method.
Abstract:
The invention relates to a method for preparing 1,6-hexanediol in which a) a muconic acid feedstock is provided that is selected from among muconic acid, muconic acid esters, muconic acid lactones, and mixtures thereof, b) the muconic acid feedstock is subjected to a reaction with hydrogen in the presence of at least one hydrogenation catalyst to obtain 1,6-hexanediol, and c) the output from the hydrogenation process in step b) is subjected to distillative separation so as to obtain 1,6-hexanediol.
