Abstract
Acids can be removed from aprotic organic liquids by bringing the liquids into contact with polyalkyleneimines that have been applied to a support. Polyethyleneimine that has been applied to amorphous silicon dioxide is particularly suitable for this method. The method can be used, for example, to eliminate acidic components from fluorinated esters.
