An object of the present invention is providing a method for producing formic acid under mild reaction conditions and by a simple procedure. As a means for achieving the object, the method for producing formic acid of the present invention is characterized by a reaction between carbon dioxide and hydrogen in the presence of an ionic liquid. According to the present invention, it is possible to generate formic acid effectively, because the method does not require that carbon dioxide be brought into a supercritical state and because no basic substances are required to be added to the reaction system.
本发明的目的是提供一种在温和反应条件和简单工艺下生产
甲酸的方法。为实现该目的,本发明的
甲酸生产方法的特征在于在
