1)  water solvent distillation
水溶剂蒸馏
1.
This paper discussed a method-water solvent distillation to get the essential oil from the residue of eucalyptus leaf oil.
水溶剂蒸馏法提取蓝桉叶油脚油中精油的方法,解决了使用真空精馏方法存在的问题,一是消除了热敏物质乙酸松油酯的分解,测得含量为6 234%(质量分数),同时得到含量为30 409%(质量分数)的主要成分α 松油醇;二是消除了烧结问题,使设备容易清洗,利于工业生产的实现。
2)  solvent distillation
溶剂蒸馏
1.
the method of solution distillation GC/MS is very useful in determining volatile compounds,application of the solvent distillation trapped the VOCS,ethyl acetate was used as the solvent.
溶剂蒸馏气相色谱-质谱法是一种有效的检测挥发性物质的研究方法,在本研究中对菜籽油中挥发性成分进行分析:将菜籽油和乙酸乙酯(V/V=2:1)混合溶解后蒸馏出溶剂,同时将蒸馏出来的挥发性组分进行富集,然后加热并用N2吹扫蒸馏液浓缩得到待测液,最后用GC/MS分析检测待测液成分。

应用气相色谱-串联质谱联用技术(GC-MS/MS)和溶剂辅助蒸馏技术(SAFE)对4种酿酒葡萄中的游离态萜烯类化合物进行了研究。
补充资料:分批蒸馏、不连续蒸馏
分子式:
CAS号:

性质:又称分批蒸馏、不连续蒸馏。它的特点是间歇操作,原料液,一次地加入蒸馏釜中,加热使其部分汽化,由于各组分间挥发度的差异,上升蒸汽中易挥发组分的含量较液相中的高,使其提浓一次,即得到一级分离。釜液的量和组成、馏出液的量和组成等参数都随时间变化,属于不稳定过程。一般当蒸馏到指定的釜液组成或馏出液的平均组成时停止操作。间歇蒸馏又可分为简单蒸馏和间歇精馏。
