The present invention provides a novel hydrogenation reaction and hydrogenolysis reaction, and does not require a large scale hydrogen supply equipment and a high-pressure facility for a respective reaction. The present invention relates to a method for producing a hydrogenated compound, characterized in reducing a compound to be hydrogenated (C) using a hydrogen-containing compound (A) and a reduced compound (B) to produce the hydrogenated compound (c).

Hydrogenation reaction method

An alternative method for efficiently producing lactic acids from a carbohydrate-containing raw material such as cellulose is provided. The method for producing lactic acid and/or lactic acid ester comprises performing heat treatment on a carbohydrate-containing raw material in a solvent containing a catalyst, wherein the catalyst is at least one type of compound selected from the group consisting of a tin compound, an indium compound, and a rhenium compound, and the solvent contains water and/or alcohol.

Method for producing lactic acids from carbohydrate-containing raw material

It is an object of the present invention to provide a basic crosslinked polymer having excellent ion exchange and catalyst properties with high resistance to thermal degradation which is, therefore, useful for a broad range of application, a method for producing said crosslinked polymer with great ease and high efficiency, and methods of using said crosslinked polymer. A crosslinked polymer having a tertiary amine and/or a quaternary ammonium salt structure, said crosslinked polymer has a tertiary amine structure at either end of at least one crosslink structure.

Crosslinked polymer, method for manufacturing it and use thereof

Active hydrogen in an active-hydrogen-containing compound is activated by using a polymer gel having a three-dimensional network structure holding a solvent inside thereof and active sites inside the three-dimensional network structure and surfaces thereof. The ratio of swell of the polymer gel is preferably set to not less than 2, and it is preferable for the polymer gel to have a basic functional group derived from at least one compound selected from the group consisting of tertiary amine compounds, quaternary ammonium salts, cyclic amine compounds and sulfides. The activation of active hydrogen in the active-hydrogen-containing compound is preferably carried out under the condition that the amount of basic active sites of the polymer gel per unit volume in the active system accompanying the activation of active hydrogen is set to not less than 0.43 mmol/cc.

High polymer gel and activation method for compounds containing active hydrogen

Crosslinked polymers excellent in ion exchange capacity and catalytic activity and in resistance to thermal decomposition and widely applicable in various fields of use; a crosslinking agent which is suited for use as a raw material in the production of crosslinked polymers; a method of producing crosslinked polymers; a method of producing a spherical particle which is suited for use in the production of crosslinked polymers; a method of producing a hydroxy alkyl (meth)acrylate; and a method of producing glycols using the crosslinked polymers are provided. The crosslinked polymer has at least one crosslink structure and a tertiary amine structure and/or a quaternary ammonium salt structure, wherein at least one crosslink structure is represented by the following general formula (1):
