  • Patent number: 5972981
    Abstract: There is provided a method for the production of improved biocidal compositions which comprise at least one 3-isothiazolinone of the general formula ##STR1## Y is a hydrogen atom or an unsubstituted alkyl radical having 1 to 18 carbon atoms, a cylo alkyl radical having 5 to 8 carbon atoms, an aralkyl radical having 7 to 11 carbon atoms or an aryl radical having 6 to 10 carbon atoms and R and R' are in each case a hydrogen atom or halogen atom or a C.sub.1 to C.sub.4 -alkyl radical, or, when taken together, R and R' contain an alkylene group to form a hydrocarbon ring, the 3-isothiazolinone being produced in known manner and then stabilized by the addition of a nitrate. The method is characterized by the fact that the mixture obtained upon the production of the 3-isothiazolinone is subjected to an additional stabilization after the addition of the nitrate by storing it at a pH of 0.2 to 2.0 and a temperature of at most 40.degree. C.

  • Patent number: 5824695
    Abstract: There is indicated a method for the production of qualitatively improved biocidal or biostatic compositions which comprise water and/or a polar organic solvent and contain at least one 3-isothiazolinone of the general formula ##STR1## in which Y, R and R' have the meanings indicated, the 3-isothiazolinone being produced in known manner and then stabilized by the addition of a nitrate. The method is characterized by the fact that the mixture obtained upon the production of the 3-isothiazolinone is subjected to an additional stabilization after the addition of the nitrate in the manner that it is stored at a pH of 0.2 to 1.5 and a temperature of at most 40.degree. C. for a period of at least 48 hours and then again brought to a higher pH. The compositions produced in this manner have an improved appearance and increased storage stability.
