Hydrolysis of biorenewable muconic acids or their corresponding lactones in high temperature water allows the selective synthesis of levulinic acids. This enables direct access to novel substituted levulinic acidsfrom biomass, creating novel opportunities for industrial applications. 3-Propyllevulinic acid was used to synthesize a novel plasticizer which performed equally well as a commercial, petrochemical
Disclosed is a catalyst for hydrogenating a carboxylic acid, comprising an activated carbon having carried thereon an active metal species comprising ruthenium and tin, wherein the activated carbon is produced by subjecting a carbonaceous material to activation treatment using zinc chloride, followed by calcination. Also disclosed is a catalyst for hydrogenating a carboxylic acid, comprising an activated carbon having carried thereon an active metal species comprising ruthenium and tin, wherein the activated carbon, prior to having carried thereon the active metal species, exhibits specific pore characteristics wherein, especially, the pore volume with respect to pores each having a radius of from 10 to 100 Å is from 0.5 to 2.0 cm3/g. Further disclosed is a method for producing a primary alcohol, which comprises reacting at least one starting material selected from the group consisting of a carboxylic acid and a carboxylic anhydride with hydrogen gas in the presence of water and the above-mentioned catalyst to thereby effect a catalytic hydrogenation of the starting material.
