Treatment of aqueous solutions obtained in the carbalkoxylation of olefinically unsaturated compounds |
摘要 |
Aqueous solutions which are obtained in the carbalkoxylation of olefinically unsaturated compounds and contain heterocyclic aromatic nitrogen bases, their transformation products and lower fatty acids and/or their salts are treated by a process in which (a) the aqueous solution is heated to 150 DEG -300 DEG C. under from 10 to 300 bar and (b) heterocyclic aromatic nitrogen bases which are formed again from the transformation products are then separated off.
