In order to have a quantitative information about the products from formaldehyde by the Bucherer-Bergs synthesis, the reaction mixture was treated on a strong cation exchange resin and the major products were determined about the effluent and eluate.<BR>In the effluent : there was relatively large amount of hydantoic acid together with hydantoin and hydantoic amide. On heating, the former was increased while the latter two were decreased.<BR>In the eluate : glycine was found together with a little amount of aminoacetonitrile and glycinamide.<BR>The synthetic route of hydantoin is, of course, through the aminoacetonitrile, during the addition of carbon dioxide, some parts of aminonitriles was directly hydrolyzed to glycinamide and further to glycine.
