紀要論文
The mechanism of the formation of the carbon dioxide compound of primary amine and its constitution and the mechanism of the formation of N, N'-di-substituted urea from primary amine-carbon dioxide compound were discussed. It was concluded that the primary amine-carbon dioxide compound was the substituted ammonium salt of substituted carbamic acid. Several kinds of N, N'-di-substituted urea R-NHCONH-R (R=n-propyl, n-amyl, p-tolubenzyl, cyclohexyl, α-phenylethyl and α-naphthomethyl) were prepared. The writers wish to express their thanks to the Ministry of Education for a grant of the Scientific Research Encouragement.
