The reactions between 3-hydroxy-2-butanone and ammoniun sulfide at 25, 50, 75, 100, 125, and 150 degrees C were studied. Four well-known flavor compounds, 2,4,5-trimethyloxazole, 2,4, 5-trimethyl-3-oxazoline, 2,4,5-trimethylthiazole, and 2,4, 5-trimethyl-3-thiazoline, were identified. Another four interesting intermediate compounds, 2-(1-hydroxyethyl)-2,4, 5-trimethyl-3-oxazoline, 2-(1-mercaptoethyl)-2
研究了在25、50、75、100、125和150摄氏度下3-羟基-2-丁酮与氨磺化物之间的反应。鉴定了四种著名的风味化合物2,4,5-三甲基恶唑,2,4,5-三甲基-3-恶唑啉,2,4,5-三甲基噻唑和2,4,5-三甲基-3-噻唑啉。另四种有趣的中间体化合物,2-(1-羟乙基)-2,4,5-三甲基-3-恶唑啉,2-(1-巯基乙基)-2,4,5-三甲基-3-恶唑啉,2-(1还通过GC-EIMS和GC-CIMS鉴定了-羟乙基)-2,4,5-三甲基-3-噻唑啉和2-(1-巯基乙基)-2,4,5-三甲基-3-噻唑啉。所有这些中间体化合物都是在25摄氏度下形成的。另一方面,四甲基吡嗪是反应温度高于100摄氏度的主要产物。
