摘要
以二苯甲烷(DPM)亚甲基作为活性氢源,研究了反应温度和反应时间对单质硫热迁移的影响。反应产物通过气相色谱质谱联用仪(GC-MS)进行了定量和定性分析。研究表明,单质硫在DPM亚甲基活性氢存在时,相对比较温和的条件下单质硫大部分以H2S的形式迁出,部分硫转变成有机化合物硫。
Using diphenylmethane （DPM） methylene as the active hydrogen source, the effects of reaction temperature and time on heat transfer of elemental sulfur were investigated. The reaction products were quantitatively and qualitatively characterized by GC-MS. The present work shows that the elemental sulfur mainly can move out in the form of H2S in the presence of DPM methylene as the active hydrogen source, another little amount of sulfur is transferred to sulfur-containing orgnie compounds.
