文摘Allantoin was synthesized with the yield as high as 68.5% using H3PW12O40. xH(2)O as catalyst. Optimum conditions for the synthesis were determined. It. was found that the heteropoly compound has higher catalytic activity than conventional inorganic acid catalysts (such as hydrochloric acid, etc.)
