Carbon-based solid acid, catalyst comprising the solid acid, and reaction using the solid acid as catalyst |
| abstract |
A carbon-based solid acid which has high activity and high thermal stability and is useful as acid catalyst for various reactions such as hydration of olefins is provided. n Namely, a carbon-based solid acid obtained by carbonization and sulfonation of an organic substance, which has a reduction rate of 10 mol% or less of acid content as measured by immersing the solid acid in hot water of 120°C for 2 hours, is used as the acid catalyst. n The organic substance to be used as the raw material for the starting solid acid is preferably a saccharide having 1-4 glycosidic bond (e.g. cellulose) or lignin. Amylose is also suitable as the raw material. Examples of the reaction for which the solid catalyst can be used include hydration of olefins, etherification of olefins, and acid/alcohol esterification. |
