| titleOfInvention | Method of obtaining cyclic acetals or their mixtures and their use as fuel additives |
| abstract | The subject of the application is a method for obtaining cyclic acetals or mixtures thereof, with the structure of acetals shown in general formula 1, in which the individual substituents R1, R2, R3, R4 are independently of each other a hydrogen atom or an alkyl group (methyl or ethyl) or a CH2OH group in that the reactor is introduced with: a heterogeneous multimetallic nanocatalyst in the form of silica-supported rhenium nanoparticles doped with nanoparticles of molybdenum and / or osmium and / or tungsten and / or iron and / or niobium and / or copper and / or nickel and / or gold, in the amount of metal doped from 0.01 to 75.0% in relation to rhenium, or a heterogeneous nanocatalyst in the form of silica-supported nanoparticles of molybdenum and / or osmium and / or tungsten and / or iron and / or niobium and / or copper and / or nickel and / or gold. The metal nanoparticles / i are below 50 nm, while the silica carrier is silica obtained using the sol-gel method, with a grain size below 100 µm, then alcohol or a mixture of alcohols and a ketone or a mixture of ketones are used, with alcohol being used pure or waste polyol selected from: glycerin and / or 1,2-propanediol (propylene glycol) and / or 1,2-ethanediol (ethylene glycol), while pure or waste acetone and / or 2-butanone is used as the ketone / or 1-hydroxyacetone, after which the reactor is sealed, the reaction mixture is sonicated by ultrasound for the time necessary to suspend the nanocatalyst in the reaction mixture, and in the final stage the reaction mixture is subjected to a temperature of 10 to 100 ° C. 0.1 to 100 hours, then the nanocatalyst is separated by a known method, and from the resulting reaction mixture, known by distillation, the main products in the form of selected cyclic acetals or a mixture of acetals are separated from the by-products which are intermediate ring closing products. The essence of the application is also the use of acetals or their mixtures thus obtained as additives to liquid fuels, in particular to gasoline or diesel, in relation to the total volume of doped fuel in the range from 1 ppm to 6% by volume. |
