Abstract: PROBLEM TO BE SOLVED: To avoid the pollution of a navigable water area by zooplankton and phytoplankton in ballast water. SOLUTION: A peroxy compd.-containing chemical agent added to ballast water contains a water soluble percarboxylic acid having 1-6 carbon atoms as a peroxy compd. and is added to ballast water in an amt. corresponding to 0.1-200 mg of percaboxylic acid per 1 l of ballast water.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aqueous germicidal agent including peracetic acid and performic acid capable of easily adjusting its effect and rapidly acting and high in bacteria-eradicating rate. SOLUTION: In the production, 0.1 to 1.0 mole of formic acid or 0.1 to 1.0 mole equivalent of the aqueous salts of formic acid per 1 kg of the germicidal agent is added as the formic acid source, to an aqueous phase including 20 to 60 wt.% of hydrogen peroxide, and balanced peracetic acid solution including 0.5 to 6 wt.% of peracetic acid, less than 10 wt.% of acetic acid and up to 3 wt.% of mineral acid, and this mixture is permitted to stand for at least 5 minutes to 5 hours before use.

Abstract: The invention relates to a method for producing a peroxyacetic acid or peroxypropionic acid solution by reacting acetic acid or propionic acid with hydrogen peroxide in the presence of a polyphosphoric acid catalyst. The catalyst used in the inventive method is a water-free solution that is obtained by dissolving 0.1 to 99 % by weight, especially 1 to 35 % by weight (based on the solution) of a polyphosphoric acid in the carboxylic acid that is to be converted to the peroxycarboxylic acid. The catalyst solution is preferably produced using molten polyphosphoric acid on the site of production of the same.

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: PCT No. PCT/EP96/03485 Sec. 371 Date May 29, 1998 Sec. 102(e) Date May 29, 1998 PCT Filed Aug. 7, 1996 PCT Pub. No. WO97/08100 PCT Pub. Date Mar. 6, 1997Owing to the concomitant storage, transport, material and handling problems and the unsatisfactory retarding of reinfection, the use of commercially available peracetic acid solutions with a high peracetic acid (PES) and acetic acid content for disinfecting large quantities of aqueous solutions, e.g. purification plant outlets, has been closely limited. It is possible to disinfect even large quantities of aqueous solutions economically and at the same time retard reinfection by using a peracetic acid solution containing 1.5 to 2.5 wt. % peracetic acid and 40 to 60 wt. % hydrogen peroxide and under 2 wt. % acetic acid as a disinfectant. The use of a peracetic acid solution with less than 1 wt. % acetic acid is preferred.

Abstract: Process for the preparation of a cationic starch having a controlled viscosity, in which, in one process step, the starch is homogenised in the presence of 10 to 35 % by weight of water and preferably 0.01 to 2.00 % by weight of a finely divided silica and/or silicate (based in each case on the total amount of the mixture) with an alkaline oxide, hydroxide, silicate or aluminate or a mixture thereof, an alkylene epoxide and a peroxy compound or a mixture of at least two peroxy compounds, and is then boiled down at the desired time.
