摘要:A method for the synthesis of cyclic acetals comprises reacting at least one carbonyl-function compound selected from aldehydes, ketones, and/or linear acetals, on a polyol in a concentrated aqueous solution exceeding 20 wt % in a reactor containing an acidic catalyst. The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.

摘要:The present invention relates to the use of a catalyst comprising a mixture of copper and zinc for continuous, gas-phase synthesis of methyl isobutyl ketone (MIBK) and/or methyl isobutyl carbinol (MIBC) from mesityl oxide. The invention also relates to a synthesis method comprising the following sequence of steps: continuous injection of the reagents in gas form through a reactor; hydrogenation reaction under pressure of hydrogen and at a temperature of between 120 and 250°C in the presence of the catalyst; condensation of the stream from the reactor and separation of the gas stream from the liquid stream; and purification of the liquid stream in order to separate the methyl isobutyl ketone and/or the methyl isobutyl carbinol.
