摘要： Provided is a method capable of manufacturing high-purity 1,3-butylene glycol having a high potassium permanganate test value, a very low content of low boiling point components, and a high initial boiling point with a high recovery rate.
A method for manufa.cturing 1,3-butylene glycol is a method for obtaining purified 1,3-butylene glycol from a crude reaction liquid containing 1,3-butylene glycol. In a dehydration column used in the dehydration step, a liquid feed containing 1,3-butylene glycol and water with an acetaldehyde content of 1000 ppm or lower and a crotonaldehyde content of 400 ppm or lower is distilled, and a liquid concentrated with a low boiling point component containing water is distilled off from above a feed plate; and in a product column used in the product distillation step, a 1,3-butylene glycol liquid feed having an acetaldehyde content of 500 ppm or lower and a crotonaldehyde content of 200 ppm or lower is distilled under a condition of a reflux ratio of higher than 0.1.

摘要： The invention relates to a process for preparing a mixture of alkylene glycols (e.g. ethylene glycol and/or propylene glycol) from a carbohydrate source by catalytic conversion with hydrogen. More specifically, the catalytic hydrogenolysis process of the invention has a decreased selectivity for larger polyols like sorbitol and erythritol, which larger polyols are obtained generally as a side product in catalytic hydrogenolysis, when viewed in comparison to the selectivity for small alkylene glycols (like ethylene glycol and propylene glycol). This is achieved by ensuring the carbohydrate feed is rich in sucrose.

摘要： A Ni—Al2O3@Al2O3—SiO2 catalyst with coated structure is provided. The catalyst has a specific surface area of 98 m2/g to 245 m2/g, and a pore volume of 0.25 cm3/g to 1.1 cm3/g. A mass ratio of an Al2O3 carrier to active component Ni in the catalyst is Al2O3:Ni=100:4˜26, a mass ratio of the Al2O3 carrier to an Al2O3—SiO2 coating layer is Al2O3:Al2O3—SiO2=100:0.1˜3, and a molar ratio of Al to Si in the Al2O3—SiO2 coating layer is 0.01 to 1. Ni particles are distributed on a surface of the Al2O3 carrier in an amorphous or highly dispersed state and have a grain size less than or equal to 8 nm, and the coating layer is filled among the Ni particles.

摘要： Disclosed is a method for producing a target compound, in which a first gas mixture includes an olefin having a first carbon number and carbon monoxide, a second gas mixture formed using the first gas mixture and containing the olefin, hydrogen and carbon monoxide, is subjected to conversion steps to obtain a third gas mixture containing a compound with a second carbon number and at least carbon monoxide The conversion includes hydroformylation. The second carbon number is one greater than the first carbon number. Using at least a portion of the third gas mixture, a fourth gas mixture which is depleted in the compound has three carbon atoms, is enriched in carbon monoxide, and is formed using at least a portion of the third gas mixture The carbon monoxide in at least a portion of the fourth gas mixture is subjected to a water gas shift to form hydrogen and carbon dioxide, and that the hydrogen formed in the water gas shift is used in the formation of the second gas mixture.
