An appropriate catalyst is found for synthesis of an unsaturated carboxylic acid and/or a derivative thereof using as a raw material compound a hydroxycarboxylic acid and/or a derivative thereof that can easily be synthesized from a polysaccharide such as biomass-derived cellulose, and an efficient method for synthesizing the unsaturated carboxylic acid and/or the derivative thereof is provided. This method is a method for synthesizing an unsaturated carboxylic acid and/or a derivative thereof, wherein an apatite compound is used as a catalyst to synthesize the unsaturated carboxylic acid and/or the derivative thereof from a biomass-derived hydroxycarboxylic acid and/or a derivative thereof by a dehydration reaction.
A method for synthesizing an unsaturated carboxylic acid and/or a salt or an ester thereof, wherein an apatite compound is used as a catalyst to synthesize the unsaturated carboxylic acid and/or the salt or the ester thereof from a biomass-derived hydroxycarboxylic acid and/or a salt or an ester thereof by a dehydration reaction, wherein Ca10(PO4)6(OH)2 is used as the apatite compound.
A method for synthesizing an unsaturated carboxylic acid and/or a salt or an ester thereof, wherein an apatite compound is used as a catalyst to synthesize the unsaturated carboxylic acid and/or the salt or the ester thereof from a biomass-derived hydroxycarboxylic acid and/or a salt or an ester thereof by a dehydration reaction, wherein a compound represented by the formula:
