Extractive distillation is defined as distillation in the presence of a miscible, high boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture.

淬取蒸馏的定义为：有易混合的、高沸的、相对难挥发的组分和溶剂存在下的蒸馏，且这些组分和溶剂不与混合物中的其它组分形成恒沸物。

High drawing rate:Because the constant supplement of solvent of the hot backset current, make crude drugs and sllvent remain

提取率高：由于热回流的新溶剂不断的补充，使药材与溶剂始终保持较高浓度梯度，加快了药材有效成份的溶出，提取较为安全。

According to practical experience and study for many years, hot condensation liquid of backset current invite within 2.5-3 hours drawing former solvent of pot all change once, can keep a higher density to the draw pot crude drugs in unit time.

回流的热冷凝液约在2.5-3小时内将提取罐原溶剂全部更换一次，使提取罐内中药材组成中溶质浸出液中的溶质在单位时间能保持一个较高的浓度差，既继承了传统提取罐二次提法的工艺，又节省了50％溶剂投放量。

When the first purification alcohol extract first enrichment, then add water to dissolve acid, then the acid fluid, finally using organic solvent basification extraction, the organic solvent extraction layer to get concentration, total alkaloid.

纯化时首先把醇提取液先浓缩，然后加入酸水进行溶解，接着再把得到的酸水液碱化，最后用有机溶剂萃取，萃取得到的有机溶剂层再进行浓缩，就得到总生物碱。

The title compound (C21H15N5O) was obtained by the reaction of 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one and 4-(2,2-dicyanovinyl)benzonitrile in water in the presence of TEBA and by recrystallization from EtOH(95%) and DMF.

The precipitation of biphenyl from twenty organic solvents using carbon dioxide as anti solvent was examined in this study.

本文以二氧化碳作为反溶剂时，探讨联苯在二十种溶剂中沈积的情形。

Based on the characteristics of paragentic manganese minerals in silver-gold ore of Guandi,the chemical phase separation selective solvent s of Al(NO_3)_3 was chosen for manganese carbide phase and H_2SO_4-KF-HF for manganite and braunite phases.

根据官地银金矿中锰矿物的共生组合情况，引用A l(NO3)3溶液作碳酸锰矿物的选择性溶剂，H2SO4-KF-HF混合溶液作水锰矿、褐锰矿的选择性溶剂，于滤渣中测定软锰矿。

Nanosized titania particles consisting of anatase, rutile and brookite phases were synthesized under solvothermal conditions with different alcohols as solvents, hexamethylene tetramine as precipitant as well as precursor of titanium trichloride.

采用不同的醇溶剂，以六亚甲基四胺为沉淀剂，以TiCl3为前驱体，通过溶剂热的方法控制合成出纳米级的锐钛矿型、金红石型和板钛矿型的二氧化钛。
