To provide a novel stabilization method for suppressing over-time denaturation of a high-purity ethylene carbonate-containing composition, a stabilized high-purity ethylene carbonate-containing composition, and the like. A method for stabilizing a high-purity ethylene carbonate-containing composition includes adjustment of content of the total of formic acid and a formic acid salt, or 2-chloroethanol to 500 ppm by mass or less in the high-purity ethylene carbonate-containing composition including 90% by mass or more ethylene carbonate.

A method of implementing organic synthesis reactions uses a composition containing a metal catalyst originating from a calcined plant. The plants can be from the Brassicaceae, Sapotaceae and Convolvulaceae family, and the metal catalyst contains metal in the M(II) form such as zinc, nickel, manganese, lead, cadmium, calcium, magnesium or copper. Examples of the organic synthesis reactions include halogenations, electrophilic reactions, cycloadditions, transesterification reactions and coupling reactions, among others.
