摘 要:松轻油是利用松根经高温干馏裂解后收集到的260℃以前的馏份,因其为深褐色,具有焦臭味,大大限制了其应用范围,为扩大用途,必须对其精制.通过多次实验,得出以8%的氢氧化钠溶液先预处理,再加入试剂经水蒸汽蒸馏,达到脱色、脱臭的目的.Under destruction, pine root is decomposed The light fraction collected under 260 ℃from the decomposed pro ducts is called oil of pine tar Because its yellow colour and stink odour, its usage is very limited In order to expand its \{usage,\} it must be defined Based on some experiments, the good process have been selected, which are that the light oil is pre created with hydroxide solution (8%) at first, then mixed with reagent, finally mixed with steam distillation Using this method, the goal for decolorizing and deodorizing the light oil of pine tar can be achieved
