摘要:
The method for producing a sulfonic acid group-containing carbonaceous material of the present invention comprises the step of carbonizing and sulfonating a polymer having a structural unit derived from resorcinol by heating in an inert gas atmosphere to obtain a sulfonic acid group-containing carbonaceous material. A catalyst comprising the resulting sulfonic acid group-containing carbonaceous material is useful for producing a target substance with high efficiency in various reactions in hydrophobic media such as alkylation reaction and polymerization reaction of olefins.
摘要:
The object is to produce a polysaccharide and/or a monosaccharide efficiently by hydrolyzing a different polysaccharide efficiently. The hydrolysis of a polysaccharide is an important means for producing a monosaccharide that can be used as a starting material for the production of ethanol, the solubilization of a water-insoluble polysaccharide, and the production of a useful water-soluble low-polymeric saccharide or the like. For achieving the object, a polysaccharide to be hydrolyzed is reacted with water in the presence of a carbonaceous material having sulfonic acid group therein to cause the hydrolysis of the polysaccharide to be hydrolyzed, thereby producing a other polysaccharide and/or a monosaccharide.
摘要:
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.
