一、引言松根轻油是在制造松焦油和松炭时,将松树根干馏获得的轻馏分副产物。过去,松根轻油曾被用作生产汽油和柴油代用品及润滑油等的原料。由于现代石油化工迅速发展,石油化工产品种类繁多,价廉物美,已不需要用松根轻油为原料生产汽油等代用品。目前,除少量松根轻油用作劣质溶剂外,绝大部分则作为锅炉燃料烧掉。我国松树资源 I. Introduction Songgen light oil pine charcoal in the manufacture of pine and charcoal, the pine root distillation obtained by light distillate by-products. In the past, pine root light oil has been used as raw materials for the production of gasoline and diesel substitutes and lubricants. As the rapid development of modern petrochemical industry, a wide range of petrochemical products, cheap, do not need to use pine root oil as raw material for the production of gasoline and other substitutes. At present, except for a small amount of pine root light oil used as a poor solvent, the vast majority are burned as boiler fuel. China’s pine resources
