浩瀚高纯联苯分析气相色谱仪GC7990

Diphenyl
Alias Name: phenyl benzene biphenyl 1,1'-biphenyl
Molecular formula: C12H10
Molecular weight: 154.21.
Biphenyl is an important organic raw material
Widely used in medicine, pesticides, dyes, liquid crystal materials. Can be used for the synthesis of plasticizers, preservatives, can also be used to make fuel, plastics and high-energy fuel. Biphenyl present in coal tar, crude oil and natural gas. There preparing biphenyl by benzene pyrolysis biphenyl chemical synthesis and through a variety of coal tar distillates made biphenyl separation extraction. Biphenyl in coal tar mass fraction of 0.20% -0.40%, the current coal tar extraction and chemical synthesis coexist.

Tengzhou City Technology Co., Ltd. Xiangying analysis developed GC7990 gas chromatograph measured the success of impurities in high purity biphenyl, with satisfactory results.
联苯
