METHOD FOR PRODUCTION OF SOLID ACID CATALYST COMPRISING CARBONACEOUS MATERIAL HAVING SULFONATE GROUP, AND USE OF THE SOLID ACID CATALYST

摘要

Disclosed is a solid acid catalyst comprising a carbonaceous material having a sulfonate group, which is useful for various acid catalyst reactions including the hydration of an olefin and has a high reaction activity. A solid acid catalyst comprising a carbonaceous material having a sulfonate group can be produced by employing a two-step process comprising heating an organic material such as a cellulose, a phenol resin, a wood plant and a grass plant to carbonize the organic material and then sulfonating the carbonized product, wherein the conditions for the carbonization and the time required for the sulfonation in the sulfonation step are controlled. The solid acid catalyst has a high reaction activity in various acid catalyst reactions including the hydration of an olefin.
