Vacuum distillation and GC-MS analysis of coal tar in low temperature from Northern Shaanxi
摘要
Abstract
Presenting the preparation of vacuum distillation with H-tar (heavy coal tar)in a low temperature coal tar from Northern Shaanxi.Seven fractions were isolated from H-tar by vacuum distillation in <100 ℃,100-200 ℃, 200-240 ℃,240-270 ℃,270-300 ℃,300-340 ℃ and 340-390 ℃ respectively,and their compositions and distributions were characterized by gas chromatography/mass spectrometry (GC-MS).The results show that the most distillate quality of fractions is in a range of 200-240 ℃,270-300 ℃ and 300-340 ℃,with their mass fractions of 12.62%,15.59% and 17.73% respectively;the fraction contains aliphatic hydrocarbons,aromatic hydrocarbons,heterocyclic compounds and a small amount of phenolic compounds;phenols mainly enrich in the fractions of 100-200 ℃,200-240 ℃ and 240-270 ℃,with their mass fractions of 63.34%,59.65% and 23.81%respectively.The main phenolic compounds in H-tar were low-rank phenols,C3-C4 alkyl-phenols,indenols, hydroquinones,naphthols and alkyl-naphthols.关键词
