摘要:
Process for preparing divinyl ethers by reacting compounds having two hydroxyl groups (hereinafter referred to as diols) with acetylene, wherein the hydroxyl groups are incompletely reacted with acetylene and the resulting product mixture therefore comprises the monovinyl ether in addition to the divinyl ether and the monovinyl ether is separated off from the product mixture by extractive distillation in the presence of an extractant.

The present invention relates to a process for the preparation of unsaturated acylamidoalkylpolyhydroxy acid amides by reacting the reaction product of polyhydroxy acid lactone and aliphatic diamine with the anhydride of a monounsaturated carboxylic acid, to the unsaturated acylamidoalkylpolyhydroxy acid amides and also to a process for the preparation of polymers of unsaturated acylamidoalkylpolyhydroxy acid amides.
摘要:
The present invention relates to a process for the preparation of monoethylenically unsaturated glycosylamines, in which an aldehyde sugar is reacted with a primary aliphatic amine or ammonia in aqueous medium and, without interim isolation, is reacted with the anhydride of a monounsaturated carboxylic acid, or an aldehyde sugar is reacted directly with allylamine, and to a process for the preparation of polymers which comprise N-acylated glycosylamine groups in copolymerized form, and to novel unsaturated N-maleinylated glycosylamines.
摘要:
A process for preparing glucose from a cellulose material, in which a cellulose-comprising starting material is provided and treated with a liquid treatment medium comprising an ionic liquid whose anions are selected from among polyatomic anions and the cellulose-comprising material which has been treated with the ionic liquid is subjected to an enzymatic hydrolysis, is described.

摘要:
The present invention relates to a process for preparing glucose from a lignocellulose-comprising starting material, in which this is firstly treated with an ionic liquid and subsequently subjected to an enzymatic hydrolysis. The invention further relates to a process for preparing microbial metabolites, especially ethanol, in which the glucose obtained is additionally subjected to a fermentation.
