Definitions

• novel biocidal compositions of the invention are comprised of a biocidally effective amount of at least one compound of formula I and preferably a carrier,
• compositions may also contain one or more other pesticidal agents.
• the biocidal compositions of the invention have remarkable bactericidal and germicidal properties which make them useful as industrial biocides for combatting fungi and bacteria which develop in aqueous or non-aqueous media used for the production of diverse industrial products. They are particularly useful for preventing and eliminating bacterial slime in paper-making circuits or in treatment of hides, vegetable tanning liquors, and leathers or in paints, lacquers, glues, ink and lubricating oils.
• Suitable compounds of formula I are m-bro'mo-wisonitroso-acetophe none described by Sassenberg [Ann., Vol. 594 (1955), p. 185], w-bromo-w-isonitroso-4-hydroxyacetophenone described by Perti. et al. [Indian J. Chem., Vol. 5 (12) (1967), p. 622] and bromo-m-isonitroso-4-methylacetophenone described by Perti et al. [Proc. Natl. Acad. Sci. India, Vol. 29 pt 3 (1960), p 287].
• compositions may also be incorporated into cosmetic soaps whose yield is capable of preventing the inconveniences caused by the presence of germs, particularly the bacteria on the surface of the human body.
• the m-bromo-m-isonitroso-acetophenones may be used to combat Aerobacter aerogenes, Pseudomonas aeruginosa, Serratia marcescens, Bacillus sublilis, Staphylococcus aureus, Escherichia coli, Flavobacterium aquaweight of Zeosil 39 (a precipitated synthetic hydrated 2 can beprepared by grinding the active compound with an inert solid or by impregnation of a solid support with .a solution of the active compound in a solvent which is next evaporated.
• a typical biocidal composition of the invention consists of a wettable powder containing 25 percent by weight of w-bromo-w-isonitroso-4-hydroxy acetophenone of formula I, 15 percent by weight of Ekapersol S (a condensation product of sodium naphthalene sulfonate), 0.5 percent by weight of Brecolane N.V.A. (sodium alkylnaphthalene sulfonate), 34.5 percent by silica) and 25 percent by weight of Vercoryl S (colloidal Kaolin).
• the novel method of the invention for combatting bacteria and fungi comprises contacting bacteria and fungi witha lethal amount of the acetophenones of formula I.
• the method is particularly useful for preventing the pollution of industrial waters such as aqueous waters in paper-making which may also contain sizing resins.
• the novel biocidal method comprise contacting bacteria and fungi with a biocidal amount of the acetophenone compounds of formula I and preferably preventing bacterial slime in aqueous media comprising incorporating a bactericidal amount of the acetophenone compounds of formula I in an aqueous media.
• the last reaction is preferably effected in an organic solvent such as methanol,ethanol, propanol or isopropanol and the reaction is more complete when terminated bromic gas.
• a method of combatting bacteria and fungi com- EXAMPLE 2 prising contacting bacteria and fungi with a lethal amount of a bactericidal and fungicidal compound of w-bromo w-isonitroso 4-hydr0xy acetophenone the formula 10 g of w-bromo-w-isonitroso-acetophenone and 10 g of sodium bromide were added to 120 ml of an ethanol 0 solution containing 17 g of hydrobromide gas per 100 LL ml and the mixture was stirred for 36 hours in a closed R -C NOH container.
