【Abstract】 A new method for the synthesis of benzylidene acetone with near critical water as reaction media was developed. The yield of benzylidene acetone was up to 46.2% after 6 h’s reaction at 260 ℃ in the absence of any catalyst. By using this new process the problems associated with neutralizing of base after reaction and disposal of salt (common to the traditional syntheses) can be avoided.更多还原
