  pine-stump light oil
     After pretreated with alkli the pine-stump light oil was rectified by packed with Mellapak SM-250 industrial column(D=300 mm,h=10.1 m) under vacuum in batch process to obtain fractions rich in such components as pinenes, camphene,limonene(dipentene) as well as p-cymene,terpenols,respectively.
     松轻油经碱液预处理后,用SM-250型工业孔板波纹填料塔(D=300 mm、h=10.1 m)以真空间歇精馏方式进行分离试验,分别得到富含蒎烯、莰烯、艹宁烯(双戊烯)及对-伞花烃、萜烯醇等组分的馏分.

This paper presents a method of synthesizing a foaming agent to be used in flotation from light pine oil. Tests for the performance of the product showed that its floating efficiency is equal to that of terpinol (oil No.2). Therefore it is possible to replace high-grade turpentine by light pine oil in the produetion of foaming agents.

本文介绍了以松轻油为原料合成浮选起泡剂的方法,并通过对天然矿的浮选试验证明,所合成的起泡剂其选矿效率不亚于2号油,从而提出了用松轻油取代优质松节油进行工业性生产浮选起泡剂的可能性。

This paper deals with the technology process of comprehensive utilization of light fraction from destructive distillation of pine roots. Hydration is applied after puriification of light fraction from destructivedistillation of pine roots,in which the process of destructive distillation turpentine oil,complex phenol oil andmore flotation oil are produced. The products process a light,stabilized color with burning smell basically vanished. Good economic benefit can be gained.

本文主要对松轻油的综合利用工艺及流程进行探讨,松轻油在用烧碱溶液和水的合理净化处理后,增加水合反应工序,采用二次正交试验设计分析,反应液松油醇含量(y)与硫酸用量(x1)、反应温度(x2)和反应时间(x3)存在如下关系:y=16.33+1.21x3-2.07x2x3-1.75x23。经分析,在45℃下反应8小时可使反应液中松油醇的含量由原来的5%左右提高到20%左右,经蒸馏得选矿油、干馏松节油、杂酚油和松焦油,产品色泽浅、稳定,焦臭气味基本消.

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...

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

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.
