The acetic acid is refined by vacuum distillation and azeotropic distillation.

以醋酸的精制可利用减压精馏蒸出和共沸精馏脱水来实现。

The activity coefficients presented in Tables 4 and 5 indicate that the dipropyl ether (1)+ 2-ethoxyethanol (3) system shows positive deviations from ideal behaviour and that the 1-propyl alcohol (2)+ 2-ethoxyethanol (3) system exhibits no deviation from ideal behaviour and no additional azeotropes are present.

表4和表5所示的活度系数表明，&二丙醚+2-乙氧基乙醇&体系与理想模型表现出正偏差而&1-丙醇+2-乙氧基乙醇&体系则无偏差，并且不存在其他共沸物。

The contents of the method are as follows: addition of entainer such as benzene, hexahydrobenzene and pentene etc, rectification make entainer, alcohol and water form ternary boiling material, then boiling point difference formed and high purity alcohol finally produced.

采用向酒精溶液添加夹带剂进行精馏，使夹带剂、乙醇、水形成三元共沸物，造成沸点差，从而精馏出纯度高的酒精。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
