Abstract
A sulfonic acid group-containing carbonaceous material that is useful as a solid acid catalyst for various reactions such as hydration of olefins and acidolysis reaction of hydroperoxide and also useful as a proton conductor material having excellent proton conductivity is provided. In addition, an economical and environmentally friendly method for producing methyl ethyl ketone is provided. A sulfonic acid group-containing carbonaceous material having high catalytic activities for various acid catalyst reactions and also having high proton conductivity can be obtained by carbonization and sulfonation of a phenolic resin.
Claims10
A method for producing a product, comprising effecting a reaction in the presence of a solid acid catalyst comprising a solid sulfonic acid group-containing carbonaceous material that is the product of carbonization and sulfonation of a phenolic resin and is in powdery form at the stage of production, wherein the reaction is selected from the group of (a) hydrating an olefin, (b) etherifying an olefin, (c) esterifying a carboxylic acid, (d) hydrolyzing a reactant selected from the group of an organic compound containing an ester bond or ether bond or both, and (e) acidolysis of an aralkyl hydroperoxide.
