研究梁河脂松节油的相对密度、折光率、初馏点、馏程体积、旋光度和化学组成以及脂松香的软化点、酸值、不皂化物含量、乙醇不溶物、灰分、旋光度和化学组成等物理和化学特征.结果表明:梁河的脂松节油在化学组成上因含有大量3-蒈烯导致其蒎烯含量低于GB/T 12901-2006,其物理指标中的折光率偏高.梁河的脂松香因化学组成中含有大量中性物,致其物理指标中酸值偏低,不皂化物含量偏高,超出GB/T 8145-2003.鉴于3-蒈烯这一特殊资源,有必要制定高3-蒈烯脂松节油标准.
研究樑河脂鬆節油的相對密度、摺光率、初餾點、餾程體積、鏇光度和化學組成以及脂鬆香的軟化點、痠值、不皂化物含量、乙醇不溶物、灰分、鏇光度和化學組成等物理和化學特徵.結果錶明:樑河的脂鬆節油在化學組成上因含有大量3-蒈烯導緻其蒎烯含量低于GB/T 12901-2006,其物理指標中的摺光率偏高.樑河的脂鬆香因化學組成中含有大量中性物,緻其物理指標中痠值偏低,不皂化物含量偏高,超齣GB/T 8145-2003.鑒于3-蒈烯這一特殊資源,有必要製定高3-蒈烯脂鬆節油標準.

Lianghe turpentine relative density, refractive index, initial boiling point, distillation range size, optical activity and chemical composition as well as the softening point, acid value, unsaponifiable matter content, ethanol insoluble matter, ash, optical activity and chemical composition and other physical and chemical characteristics of rosin gum were studied. The results showed that the gum Lianghe in the chemical composition of turpentine contained a large number of 3 - carene, pinene content was lower than GB / T 12901-2006 and in physical indicators refractive index was high. Lianghe rosin gum contained a large number of neutral objects, hence the physical indicators of their low acid value, high levels of unsaponifiable matter in excess of GB / T 8145-2003. For 3 - carene is a kind of special resources, a 3 - carene standard of gum turpentine is necesarry.
