From IR remarking the bending band of triazine ring corresponded to 800cm^<-1>, the temperatures at which respective compounds cyclize are determined. In UV, the absorption of ammeline, ammelide, melam, melem, thioammeline are clearly decided from which could also be followed the proceeding of cyclization. And, in X-ray diffraction the changes of intermedates in the thermal decomposition are checked as it were qualitative owing to the important information that the diffraction line becomes simple as the cyclization increases. Combining these three techniques mentioned above, the course of thermal decomposition was qualitatively presumed., 著者らの研究室にて,従来よりトリアジン系化合物の分解と生成についての研究を行なっている。そのうちの含イオウシァナミド誘導体(チオ尿素,チオシアン酸アンモエウム,2.4-ジチオビウレット,グアニルチオ尿素)の熱分解の研究については熱分解生成物のX線回折の測定結果が末報告であるのでここに吸収スペクトル(IR, UV)とともに総括して報告する。3種の測定手段を組み合わせる手法はこの反応については新規であってこれにより,定性的に熱分解機構を解明することができた。, Article, 富山大学工学部紀要,22}, pages = {27--32}, title = {含イオウシアナミド誘導体の熱分解生成物のIR,UVおよびX線回折による検討}, volume = {22}, year = {1971} }
