    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.degree. to 500.degree. C. and followed by reacting the resultant product with an alkali metal at a temperature of from 180.degree. to 350.degree. 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.degree. C. and then reacting the reaction product with an alkali metal at a temperature of from 180.degree. to 350.degree. C.
