新戊二醇主要用于制造高档树脂和粉末涂料,工业上采用甲醛和异丁醛缩合合成.加氢法工艺用三乙胺催化,然后进行催化加氢.新戊二醇废水中含有甲醇、异丁醛、异丁醇、辛醇等高附加值组分和不能进生化处理的三乙胺,废油中含有新戊二醇和羟基特戊酸新戊二醇单酯等.
本研究对于废水采用普通精馏从塔顶采出异丁醛和甲醇；塔釜残液进入萃取塔以辛醇为萃取剂进行液液萃取；萃余相由塔底采出,萃取相进入精馏塔由塔顶依次采出三乙胺、异丁醛,塔底采出辛醇作为萃取剂部分循环使用返回萃取塔.萃取相通过精馏塔得到精制,塔底采出萃取剂辛醇循环使用,回收循环方便、工业上易实现.对于废油采用真空下精馏分离,使塔内的压力降低,沸点降低,有利于组分的分离,从而降低能耗.
系统研究了分离组分的物性,确定了废水、废油组分的分离方法.回收率可达95%以上,节能效果明显.

New e erchun main used in the manufacture of high-grade resin and powder coating and industrial formaldehyde and butyl aldehyde using different synthesis condensation. With three procedures method technology hydrogenation catalyst and catalytic hydrogenation. New e erchun wastewater containing methanol, different butyl aldehyde, different butanol, xinchun high value-added component and can't get into the biological treatment of three procedures, oil contains new glutarie alcohols and hydroxyl acid, e new e erchun single ester etc.
This research for waste water from the top of the column can using common distillation different butyl aldehydes and methanol; Tower kettle residual liquid into the extraction tower to xinchun for extracting agent for liquid-liquid extraction; More from the bottom and admired in recovery, extraction phase into the top of the column in turn was produced by three different aldehydes, butyl, bottom recovery xinchun as extractant recycling return extraction of tower. Extraction phase through the column to get refined, bottom recovery extraction solvent xinchun recycling, recycling convenient, easy to realize industry. For the oil under vacuum distillation separation, make the tower in pressure reducing, reducing the boiling point, be helpful for the separation of components, so as to reduce energy consumption.
The separation of research system components property, determine the waste water, residues of components separation method. Recovery can be 95% more, and energy saving effect is obvious.
