摘要
由异戊醇的精馏系数(k′)理解,在酒精蒸馏过程中,从精馏塔酒精浓度42%(v/v)处提杂醇油最适宜。杂醇油是易分离组分,在精馏塔乙醇与水分离的同时可以将杂醇油彻底分离。液相取油与汽相取油没有本质区别。理论与实践证明,连续取油优于间歇取油。
According to the rectification coefficient (k) of the isoamyl alcohol,it is suitable for the fusel oil to be extracted in the layer of 42%(v/v) alcohol concentration in the rectification column.The fusel oil is easily separated.While ethyl alcohol is separated from water in rectification column,it can be entirely separated.There is no essential difference between the vapor phase extraction and liquid phase extraction of fusel oil.The theory and practice have proved that the continuous extraction of fusel oil is much better than intermittent extraction of fusel oil.
