| 摘 要： | 利用气相色谱-质谱(GC-MS)法对联苯中所含的主要杂质物进行定性研究,同时利用标样用气相色谱法确定杂质为二苯甲烷、2-甲基联苯、3-甲基联苯和4-甲基联苯。进一步用溶剂结晶法去除了联苯中的杂质,获得99.9%以上联苯。

| Abstract: | Qualitative study was made on the impurities in biphenyl by GC-MS. The impurities determined with the standard samples by gas chromatography were diphenylmethane,2-methyl biphenyl,3-methyl biphenyl and 4-methyl biphenyl. Then they can be further recrystallized to produce biphenyl with a purity of over 99.9%. |
