  • Agent for dosing aqueous systems with acrolein, processes for making same, and method of treating an aqueous system
    Patent number: 5352841
    Abstract: Liquid acrolein, whose hazardous properties make handling difficult, is used to dose aqueous systems with acrolein in a biocidally effective concentration. Disclosed are agents which increase the ease and safety of acrolein handling and which are characterized by a content of 30 to 95% by weight acrolein and 5 to 70% by weight inorganic carrier materials. Silicas are the preferred carrier materials. The powdery or highly viscous mixture of substances will preferably exist in molded form and is additionally provided with a cladding that is impermeable to acrolein vapor. In dosing the aqueous systems, the agents are introduced directly in the water whereupon the acrolein is released.
