正戊醇-乙酸-水三元体系等温等压相图的绘制 摘要:为了体验不借助任何仪器就可以做出富有意义的研究工作,并学会使用origin绘制三相图。本次实验通过浊点法测定三元溶液体系正戊醇-乙酸-水的等温等压相图,以及酸碱滴定法测量该体系中液-液二相平衡的连接线。实验过程中体会到了酸碱滴定和标定操作的重要性,懂得了三相图的分析方式。该实验采用的试剂环保,毒性小,锻炼了实验员的实验操作能力,更加熟练origin软件画图方法。 关键词:三相图 酸碱滴定 浊点法 Abstract In order to experience without the aid of any instrument can make meaningful research work, and learn to use a three-phase diagram drawing origin. The experiment by the cloud point determination Ternary Solutions amyl alcohol - acetic acid - water isothermal isobaric phase diagram, as well as acid-base titration measurements of the system of liquid - liquid equilibrium of two cables. During the experiment realized the importance of the acid-base titration and calibration operation, to understand the way of a three-phase diagram analysis. Reagent used in this experiment green, toxicity, exercise capacity laboratory assistant of experimental operation, more skilled origin software drawing methods. Keywords Three-phase diagram acid-base titration cloud point 在物理化学理论课上,我们曾学到相平衡课程,主要是理论部分,没有进行实践,尤其是三组分系统的理论更少。而在生活中,很多都是和三组分相图相关,因此对三组分相图的实验部分充满好奇。在课本上曾提到过醋酸-***仿-水,乙醇-苯-水,但是苯和***仿的毒性都过高。故此次通过正戊醇-乙酸-水三相,通过origin绘图,得到三相图,并进行分析。
