METHOD FOR PRODUCING ALCOHOL

The present invention provides a method for selectively producing an alcohol by efficiently hydrogenating a lactone. The present invention is a method for producing an alcohol, the method including hydrogenating a substrate lactone represented by Formula (1), in the presence of a catalyst described below, to produce an alcohol that is represented by Formula (2). In the formulae, R represents a divalent hydrocarbon group which may have a hydroxyl group. The catalyst comprises: metal species including M1 and M2; and a support supporting the metal species, and wherein M1 is rhodium, platinum, ruthenium, iridium, or palladium; M2 is tin, vanadium, molybdenum, tungsten, or rhenium; and the support is hydroxyapatite, fluorapatite, hydrotalcite, or ZrO2.

METHOD FOR PRODUCING 1,3-BUTANEDIOL

PROBLEM TO BE SOLVED: To achieve high conversion rates and selectivity coefficients in producing 1,3-butanediol by performing the hydrogenation of acetaldol obtained by the condensation of acetaldehyde. SOLUTION: A method for producing 1,3-butanediol includes hydrogenating acetaldol with a hydrogen gas, using a hydrogenation catalyst. From a reaction solution after hydrogenation, a low-boiling component of a reaction by-product is separated and collected, and all or part of the low-boiling component is used to dilute acetaldol as raw material, after which hydrogenation is performed.

Method for synthesizing 1, 3-dihydric alcohol by using olefin and methanol as raw materials

The invention discloses a method for preparing 1, 3-dihydric alcohol by taking olefin and methanol as raw materials through one-step reaction and a catalyst for the method. The method comprises the following steps: 1) adding a catalyst into a reactor, heating and reducing in a hydrogen-nitrogen mixed atmosphere, then cooling to 60-180 DEG C, and keeping the pressure in the reactor to be 0.5-8 MPa for reaction; 2) respectively introducing olefin and a methanol aqueous solution into the reactor for reaction, wherein the airspeed is 0.01-10h in terms of methanol; 3) enabling that the reaction product enters a product storage tank after condensation and gas-liquid separation; and 4) carrying out rectification separation on the reaction product obtained in the step 3) to obtain a 1, 3-dihydric alcohol product with the purity of more than 99%. The method provided by the invention has the advantages of low raw material cost, simple steps and continuous production.
