Process for preparing solid base.

摘要

A solid base with improved properties, particularly excellent catalytic performance is prepared by reacting alumina and an alkali metal hydroxide at a temperature of from 200 DEG to 500 DEG C. and followed by reacting the resultant product with an alkali metal at a temperature of from 180 DEG to 350 DEG C. or reacting water-containing alumina and an alkali metal in such an amount that corresponds to a molar equivalent of water contained in alumina at a temperature in a range between a melting point of the alkali metal and 500 DEG C. and then reacting the reaction product with an alkali metal at a temperature of from 180 DEG to 350 DEG C.
