Abstract
Aqueous solutions can be doped in a simple, safe and economic manner with acrolein in biocidally effective concentration by converting acrolein acetals in aqueous phase in the presence of a strongly acidic deacetalation catalyst into acrolein, cleaving the alcohol component, constantly removing the formed acrolein from the decetalation mixture and transferring it by means of an inert gas stream or a liquid jet pump with the aqueous solution to be doped as jet fluid into the aqueous solution to be doped.
