    Abstract: PROBLEM TO BE SOLVED: To obtain the subject polymer for a bactericide, etc., capable of inhibiting growth of undesirable seaweeds and plants by adding highly purified acrolein to an alkali aqueous solution containable an emulsifier, etc., with keeping a room temperature and neutralizing with an aqueous solution of mineral acid. SOLUTION: This acrolein-releasable emulsion homopolymer releases acrolein in an aqueous system at a pH higher than 7 and a bactericidal action is exhibited by the releasing to inhibit growth of undesirable seaweeds and plants, thus is useful as a very effective bactericide in treating a waterway or for control of a sulfate reducing bacterium in investigation of petroleum. The emulsion homopolymer is obtained by previously charging an alkali aqueous solution containable of an emulsifier or a humectant in a tank, adding acrolein preferably having >=95wt.% purity to the solution while keeping a temperature at

    Abstract: The agent contains an aqueous percarboxylic acid with 1 to 6 carbon atoms as peroxygen compound, to which ballast is added water in an amount corresponding to 0.1 to 200 mg percarboxylic acid per liter. Process for avoiding contamination of navigatable body of water with organisms selected from plankton, e.g. epifauna and photo plankton including cystenes, comprises adding reagent containing peroxygen compound to the ballast water, allowing the reagent to react until the organisms are destroyed and feeding the treated water back into the body of water.

    Abstract: Flowing waters are dosed with acrolein to prevent excessive plant and algal growth. In order to avoid transport of acrolein, the process according to the invention, using the apparatus according to the invention, generates acrolein at the site of use by deacetylization of an acrolein acetal in the presence of an aqueous mineral acid, for which no electrical energy is required. According to the invention an acrolein acetal solution and an aqueous mineral acid solution are transported from pressure-resistant storage vessels (1) and (2) into a mixing chamber (11) by applying a pressure from a pressurized gas cylinder (3) and the mixture is passed through a deacetalization reactor; the reactor to be used comprises a tubular (14) and a vessel-like (15) part.
