摘要： This invention provides a method for preparing a polyoxymethylene dimethyl ether carbonyl compound and/or methyl methoxyacetate as intermediates for producing ethylene glycol, which comprises passing a raw material: polyoxymethylene dimethyl ether or methylal together with carbon monoxide and hydrogen gas through a reactor carrying an acidic molecular sieve catalyst, and performing a reaction to prepare a corresponding product under an appropriate condition where no other solvent is added, wherein the process of the reaction is a gas-liquid-solid three-phase reaction. In the method of this invention, the raw material of polyoxymethylene dimethyl ether or methylal has a high conversion rate, each product has a high selectivity, the catalyst has a long service life, additional solvents are not required to be used, and reaction conditions are relatively mild. The method of this invention enables continuous production and has the potential for industrial application. Also, ethylene glycol may be produced by subjecting the resultant product to hydrolysis after hydrogenation or hydrogenation after hydrolysis.

摘要： This invention discloses a method for producing ethanol and coproducing methanol on a catalyst in a reactor using a co-feed of a synthesis gas and acetate as a reaction raw material. More particularly, this invention provides a method for producing ethanol and coproducing methanol, characterized in that the method comprises the step of passing a raw material gas containing an acetate and a synthesis gas through a reactor loaded with a catalyst to produce ethanol and coproduce methanol under the conditions of a reaction temperature of 150-350°C, a reaction pressure of 0.1-20.0 MPa, a reaction volume hourly space velocity of 100-45000 mlg -1 h -1 , and an acetate weight hourly space velocity of 0.01-5.0 h -1 ; and the active components of the catalyst are copper and optionally zinc and/or aluminum. The method of this invention greatly facilitates the conversion of carbon monoxide to methanol, while an extremely high activity of acetate hydrogenation is maintained. Also, the method of this invention produces ethanol while a certain amount of methanol is coproduced, and the proportions of ethanol and methanol may be adjusted, which increases the flexibility of products.
