A method for producing 1,4:3,6-dianhydrohexitols, including the steps of: a) supplying at least one hexitol, b) dehydrating the hexitol, and c) distillating the dehydration product produced in step b), wherein: the hexitol is supplied in the form of an aqueous solution in step a); and the distillation is carried out by means of a thin-film evaporator in step c).

Method for producing dianhydrohexitol with a step of distillation on a thin-film evaporator

A process for manufacturing crystals of 1,4:3,6-dianhydrohexitols, by manufacturing a solution of an internal dehydration product of at least one hexitol, distilling the solution, crystallizing, and wherein the crystallization mother liquors undergo a step of evaporative crystallization. Unlike the prior art processes that seek to recycle the crystallization mother liquors, evaporative crystallization economically and efficiently replaces the succession of steps consisting of at least one concentration, then at least one step of purification by distillation, chromatography, or crystallization.

The invention relates to a starch hydrolysate having a Dextrose Equivalent DE of between 5 and 30 and a specific carbohydrate profile. In particular, the hydrolysate of the invention has improved retrogradation behaviour. The invention also relates to a method for the production of said starch hydrolysate.

Low-viscosity starch hydrolysate with improved retrogradation behaviour

A process for producing bis-anhydrohexitol ether compositions and in particular isohexide glycidyl ether compositions, one of the originalities of which is azeotropic distillation carried out under reduced pressure. Such compositions are used to produce epoxy resins, the function thereof being to form a three-dimensional macromolecular network. The compositions obtained according to the process are rich in diepoxy derivatives of isosorbide to the detriment of monoepoxy derivatives, only the first participating in the formation of the three-dimensional network. The crosslinking density is therefore increased, thereby making it possible to obtain a material which is more chemically resistant and mechanically stronger and which has a higher glass transition temperature (Tg), compared with the same materials obtained with bis-anhydrohexitol ether compositions according to the prior art.

Process for producing isohexide glycidyl ethers, products thus obtained, and uses thereof

A method for improving the stability of compositions of a product for internal dehydration of a hydrogenated sugar, in particular an isosorbide composition, the method involving the use of monoethanolamine, diethanolamine, triethanolamine and the mixtures thereof as a stabilization agent.

A method for selective hydrogenation of furan-2,5-dialdehyde (DFF) into 2,5-di(hydroxymethyl)furan (DHMF) and into 2,5-di(hydroxymethyl)tetrahydrofuran (DHMTHF). In relation to the prior art, which uses C6 sugars or 5-hydroxymethyl furaldehyde (5-HMF) as raw materials, the method can be performed at low temperatures (lower than 120&#xb0; C., preferably 80&#xb0; C.), while consuming low amounts of catalyst relative to the initial reagent (in particular less than 5%, preferably less than 2% relative to the weight of the reagent). The heterogeneous catalyst used can also be recycled from one reaction to another. Finally, the choice of experimental conditions enables the selective formation of DHMF or DHMTHF.

Method for synthesising 2,5-di(hydroxymethyl)furan and 2,5-di(hydroxymethyl)tetrahydrofuran by selective hydrogenation of furan-2,5-dialdehyde

A method for synthesizing 2,5-furandicarboxylic acid (FDCA) from furan-2,5-dialdehyde (DFF). The method is industrially applicable due to the simplicity and availability of the reagents used, and due to the experimental conditions on which the method is based: the method requires low temperatures and enables a reaction under atmospheric pressure, the reaction times being relatively short. Furthermore, the method does not lead to the formation of salts that need to be treated downstream from the method, and the catalytic ratio relative to the initial product is particularly low.
