| titleOfInvention | The method of utilizing dihydroxyl alcohols to acetic acid |
| abstract | The subject of the invention is a method of utilizing dihydroxyl alcohols preferentially to acetic acid, especially wastes of dihydroxyl alcohols, such as: ethylene glycol, 1,2 - propanediol, 1,3 - propanediol, 2,3 - butanediol, as well as mixtures thereof, especially which are post-reaction waste , in particular in the process of large-scale production of organic compounds. The method consists in entering into the reactor a heterogeneous nanocatalyst containing less than 15 nm gold grains in an amount of 0.01 to 1.0%, deposited on a support in the form of amorphous silica obtained by the sol - gel method with grain size less than 4 µm, in an amount of 99.99 to 99% or a heterogeneous nanocatalyst containing gold grains, in an amount of 0.01 to 2.0%, deposited on copper in the form of grains with a size of 100 µm, in an amount from 99.99 to 98.0%, then dihydroxyl alcohol or an aqueous solution of such alcohol with a content below 1.0 mol / L or a mixture of dihydroxyl alcohols and an oxidant is added, after which the system is sonicated by sonication during necessary to suspend the nanocatalyst in the reaction mixture, followed by oxidation reaction of a dihydroxyl alcohol or an aqueous solution of such alcohol or a mixture of alcohols at a temperature of 10 to 120 ° C, depending on the oxidized alcohol, at a pressure of 0.1 to 20 bar, at at least 1 hour, preferably 20 hours, resulting in the product in the form of acetic acid and, depending on the oxidized alcohol, by-products, especially acetone and / or glycolaldehyde and / or 2-oxobutan-3-ol and / or 3-hydroxypropanoic acid and / or formic acid and traces of alcohol esterification products. |
