邻苯二胺产品中针状未知化合物的结构鉴定

Identification of Needle-shaped Unknown Compound in o-Phenylenediamine

摘要: 从邻苯二胺产品中分离出一种白色针状未知化合物,用液相色谱(HPLC)和气相色谱(GC)鉴定其纯度后,同时进行元素、红外光谱(IR)、紫外光谱(UV)、质谱(MS)、核磁共振(NMR)氢谱及碳谱分析。根据分析的结果进行解析,最后确定未知针状不纯物中其主成分为2,1,3-苯并硫咪唑或2,1,3-硫二氮杂茚(C₆H₄N₂S)(2,1,3-benzothiadiazole).

Abstract: An unknown needle shaped compound was separated from o-phenylenediamine. The purity was certified by HPLC and GC. Meanwhile, the analyses were proceeded in element, IR, UV, MS, NMR(¹H and ¹³C). The results of analysis indicated that the unknown compound was 2,1,3-benzothiadiazole(C₆H₄N₂S).
