In the process of producing terebinth and colophony , it ' s difficult to measure the amount of terebinth in the turpentine on line , but it ' s the key to realize automatic control for the whole process 在蒸汽蒸馏连续法生产松香和松节油的过程中，澄清阶段的松节油含油量大小的在线检测一直是一个难点，也是整个生产过程实现自动控制的关键。
Properties : white light powder with specific specific gravity of 1 . 095 , soapy , insoluble in water , but soluble in organic solvent such as hot ethanol , benzene and terebinth etc . and decompounds into stearate and zinc when meeting strong acid 物理性能：硬脂酸锌，为白色轻质粉状，比重1 . 095 ，有滑腻感，不溶于水，溶于热的乙醇、苯和松节油等有机溶剂，遇强酸则分解为硬脂酸和相应的锌盐。
Special properties and uses : it ‘ s main component is pinene , with special chemical activity , it is a good solvent and an important raw material for the manufacture of coating , synthetic camphor , synthetic resin , synthetic spices and other organic industrial products etc 1性质和用途:松节油的主要成分是蒎烯,具有特殊的化学性质,是一种优良的溶剂,是涂料,合成樟脑,合成树脂,和其他有机合成工业的重要原料
There couldn t anything wake them up all over , and make them happy all over , like a dog fight - unless it might be putting turpentine on a stray dog and setting fire to him , or tying a tin pan to his tail and see him run himself to death 再也没有什么别的事情，能象一场狗打架那样能叫他们精神陡然振作起来，叫他们全身欢快起来除非是在一条野狗身上浇些松节油，点上一把火，或是把一只白铁锅拴在狗尾巴上，眼看着这条狗不停地奔跑，到死为止。
In order to solve the problems with heavy turpentine , such as complex constituents , vicinal boiling point , difficult to separation and hard to comprehensive utilization , the - santalene was converted to natural structure similar product - santalol by light - oxidize reaction , and caryophyllene epoxide was obtained at the same time 摘要为了解决重质松节油组成复杂、沸点相近导致分离困难、难以深加工综合利用等问题，利用光氧化反应技术，将其中的-檀香烯转化为与天然-檀香醇结构相似的檀香型新香料-檀香烯醇，同时可得到环氧石竹烯。

The results showed that the female parasitoids in different microhabitats from pine needles , pine barks , turpentine , and fir barks respectively , responded positively to the corresponding volatiles when they were offered with a two - ways choice between blank and the volatiles previously experienced at emergence and the early stage of adult , but the females showed no learning behavior to fir leaves though they had experienced the fir leaves microhabitats 结果表明，川硬皮肿腿蜂羽化期和成虫初期经历松枝皮、松针、松节油、杉枝皮等的挥发物后，雌蜂对这些挥发物的选择性明显提高，但对杉叶挥发物无明显的学习行为。
Unsaturated alkynyl alcohols , such as dehydronerolidol , dehydrogeranyllinalool , and dehydroisophytol , were prepared by ethynylation of turpentine derivatives , namely terpenylacetones , e . g . geranylacetone , farnesylacetone , and phyton under normal pressure in presence of alkali metal hydroxide and organic solvents 摘要松节油衍生物格萜烯基丙酮，如香叶基丙酮、金合欢基丙酮和植物酮在常压条件，碱金属氢氧化物和有机溶剂存在下可发生乙炔化反应，形成对应的， -不饱和炔醇化合物脱氢橙花叔醇、脱氢香叶基芳樟醇和脱氢异植物醇。
