General description

Valeric acid is a renewable chemical that can be obtained via hydrogenation of levulinic acid in the presence of nickel-based catalyst or from lignocellulosic biomass. It can undergo esterification to form valerate esters, which can find applications as blending agents for gasoline and diesel, used in the production of biofuels.
