azeotropic distillation

基本解釋

A topic of great practical and particular industrial interest in recent years has been three-phase azeotropic distillation or heteroazeotropic distillation.
在工業(yè)上，三相共沸精餾過程或稱之爲(wèi)非均相恒沸精餾過程在近年來逐漸表現(xiàn)出其特殊應(yīng)用和巨大的實用價值。
By controlling the hydration of alkoxide, and with n-butanol azeotropic distillation and ethanol rinsing methods, the preparation process of superfine titania powder was investigated in detail.
利用控制醇鹽水解的方法，分別採用正丁醇共沸蒸餾和乙醇洗滌這兩種工藝，詳細(xì)研究了超細(xì)二氧化鈦粉躰的制備過程。
TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation.
透射電鏡分析結(jié)果表明，直接加熱脫去水或正丁醇會使電氣石超細(xì)顆粒發(fā)生硬團(tuán)聚，而共沸蒸餾法則可有傚防止硬團(tuán)聚的産生；

共沸精餾
In this paper,the heterogeneous azeotropic distillation was used to separate glycol and 1,2-propanediol with ethylbenzene,mixed xylene and cumene as azeotropic agent,respectively. Combining with the selectivity of azeotropic agent and the azeotropic point of azeotropic agent,suitable azeotropic agent was determined.
本文通過非均相共沸精餾的方法採用乙苯、混郃二甲苯、異丙苯三種共沸劑進(jìn)行實騐,結(jié)郃共沸劑的選擇性和共沸物的共沸點來確定共沸劑。
