We Factory export forest products as follows:Gum Rosin,Gum Turpentine(All products take to make by best,advanced and universal's a spectrum of steam method,and we severely differentiate material make into 100% Pinus Massoniana,Pinus Marsh,pinus elliotiis and Pinus mixed etc foru products),Pine Oil,Terpineol,α-Pintene,β-Pintene any rosins,Tung Oil,Cassia,Star Aniseed etc.our export have exceed 15years.

我司经常出口的林化产品有：脂松香、脂松节油（全部采用当前中国最先进和常用的连续蒸汽法生产，并严格区分原料生产出纯马尾松、湿地松、南亚松经合松四种产品）、松油、松油醇、α-蒸烯、β-蒎烯、各种树脂产品以及桐油、桂皮、八角等。其中，脂松香和脂松节油是我们的传统出口产品，已有15年的历史了。

The characteristic properties of three kinds of turpentine prepared by steam distillation method had all met the super grade requirements of China national standard——GB/T 12901-2006 "Gum turpentine".

摘 要：对比研究了溶剂法和水蒸气蒸馏法制备马尾松、湿地松和思茅松松节油的工艺，使用水蒸气蒸馏法制得的3种松节油样品均符合国家标准《脂松节油》GB/T 12901-2006的质量指标要求。

Studies on synthesis and selective oxidation of optical perillyl alcohol are an important procedure to develop abundant turpentine oil of our country and to synthesize a series of fine chemicals.

光学活性紫苏醇的合成及其选择性氧化研究是开发我国丰富的松节油资源，利用松节油合成一系列精细化学品的一条重要途径。

And application of turpentine oil in conventional pesticide and non-biocidal pesticide juvenile hormone analogs were discussed.

并对松节油在传统杀虫剂和非杀生性杀虫剂保幼激素类似物方面的研究进展进行了论述，同时还介绍国内外利用松节油合成的一些典型杀虫剂和新产品、及其一般的合成方法。

The repellent rate of clove oil and turpentine oil to Blattella germanica reduced fast by the time, especially the turpentine oil showed very weak repellent effect in a week.

在持效性上，丁香油和松节油对德国小蠊的驱避性都随时间推移有明显的递减，特别是松节油，一周后效果已很弱。

Turpentine turpentine have Shujin external active, promoting blood circulation, reducing the role of check turpentine 1, warm 8, with gauze soaked Shikishima scleroma, the best coverage at the gauze on热水袋5-10 minutes, until the skin redness or removed.

松节油外敷松节油有舒筋活络、活血、消肿作用，取松节油1份，温水8份，用纱布浸湿敷硬结处，最好在纱布上覆盖热水袋5-10分钟，至皮肤发红即取下。

The experimental results showed that under the reaction temperature of 80℃,using catalyst 5 % of the mass of turpentine,reaction time of 10 h,turpentine:solvent:assistant:water of 1∶1∶1∶2,the conversion ratio of 90 %,the selection of α-Terpineol production was 64.96 %,and ΔHφf,g and Sφg were estimated as well...

实验结果表明，在反应温度80℃，催化剂用量为松节油质量的5%，反应时间10 h，松节油∶溶剂∶助剂∶水为1∶1∶1∶2时，其α-蒎烯的转化率为90%，生成α-松油醇的选择性为64.96%。并对α-蒎烯和松油醇理想气体的△Hfφ，g、Sgφ进行了估算，为今后的理论研究提供了数据支持。

It has offered the information of the boiling points of the chemical compounds, and it is helpful to reutilize them after their separation by rectification. The results showed that the main compounds of the heavy cut of terpineol were longifolene and βcaryophyllene. They are from the raw material, terpinene oil.

松油醇的合成工艺方法主要有两种：一种是一步法，即松节油在酸催化作用下直接进行水合反应生成松油醇；另一种是二步法，即松节油首先在酸催化作用下水合成萜二醇，再经稀酸催化脱水生产松油醇。
