See also:HYDANTOIN (glycolyl See also:urea), C3H4N202 or CO< NH•See also:CH2 NH•CO the ureide of glycollic See also:acid, may be obtained by See also:heating See also:allantoin or alloxan with hydriodic acid, or by heating bromacetyl urea with alcoholic See also:ammonia. It crystallizes in needles, melting at 216° C. When hydrolysed with baryta See also:water yields hydantoic (glycoluric) acid,See also:H2N • CO .NH . CH2• See also:CO2H, which is readily soluble in hot water, and on heating with hydriodic acid decomposes into ammonia, See also:carbon dioxide and glycocoll, CH2•See also:NH2•See also:CO2•H. Many substituted hydantoins are known; the a-alkyl hydantoins are formed on See also:fusion of aldehyde- or ketone-cyanhydrins with urea, the '3-alkyl hydantoins from the fusion of mono-alkyl glycocolls with urea, and the 7-alkyl hydantoins from the See also:action of alkalis and alkyl iodides on the a-compounds. y-Methyl hydantoin has been obtained as a splitting product of See also:caffeine (E. See also:Fischer, See also:Ann., 1882, 215, p. 253). End of Article: HYDANTOIN (glycolyl urea), C3H4N202Additional information and CommentsThere are no comments yet for this article.
