Abstract: THE PRESENT INVENTION RELATES TO CERTAIN PROCESSES AND COMPOSITIONS USEFUL FOR INHIBITING AND/OR CONTROLLING THE GROWTH OF SLIME IN WATER AND, IN PARTICULAR, WATER EMPLOYED FOR INDUSTRIAL PURPOSES. WATER EMPOLYED IN COOLANUFACTURE OF PULP PAPER AND WATER EMPLOYED IN COOLING WATER SYSTEMS, AS WELL AS OTHER INDUSTRIAL WATERS, PROVIDE ENVIRONMENT WHICH ARE CONDUCTIVE TO SLIME FROMATION. THE NOVEL COMPOSITIONS OF THE PRESENT INVENTION ARE MIXTURES WHICH SHOW UNEXPECTED SYNERGISTIC ACTIVITY AGAINST MICROORGANISMS, INCLUDING BACTERIA, FUNGI AND ALGAE, WHICH PRODUCE SILIME IN AQUEOUS SYSTEMS. THE SLIME, OF COURSE, IS OBJECTIONABLE FROM AN OPERATIONAL AND/OR AN AESTHETIC POINT OF VIEW. SPECIFICALLY, THE INVENTION IS DIRECTED TO AND THE USE OF COMPOSITION COMPRISING A COMBINATION OF 3,3,4,4-TETRACHLOROTETRAHYDROTHIOPHENE1,1-DIOXIDE (OR DERIVATIVES THEREOF) AND BIS(TRI-N-BUTYL TIN) OXIDE. THE INVENTIVE COMPOSITIONS INHIBIT THE GROWTH OF SLIME IN WATER, OR MORE SPECIFICALLY, POSSESS BIOCIDAL ACTIVITY AGAINST BACTERIA, FUNGI AND/OR ALGAE.

Abstract: The present invention relates to certain processes and compositions useful for inhibiting and/or controlling the growth of slime in water and, in particular, water employed for industrial purposes. Water employed in the manufacture of pulp paper and water employed in cooling water systems, as well as other industrial waters, provide environments which are conducive to slime formation. The novel compositions of the present invention are mixtures which show unexpected synergistic activity against microorganisms, including bacteria, fungi and algae, which produce slime in aqueous systems. The slime, of course, is objectionable from an operational and/or an aesthetic point of view. Specifically, the invention is directed to and the use of compositions comprising a combination of 3,3,4,4,tetrachlorotetrahydrothiophene-1,1-dioxide and anionic sulfonate surfactants (or mixtures thereof). The inventive compositions inhibit the growth of slime in water, or more specifically, possess biocidal activity against bacteria, fungi and/or algae. The anionic sulfonate surfactants contemplated for use in accordance with the present invention may be exemplified by: alkali metal linear alkylate sulfonate, wherein the alkylate contains from 10 to 18 carbon atoms; and alkali metal-N-lower alkyl-N-high alkenoyl taurate, wherein the lower alkyl contains from 1 to 4 carbon atoms and the alkenoyl contains from 16 to 20 carbon atoms.

THE SLIME, OF COURSE, IS OBJECTIONABLE FROM AN OPERATIONAL AND /OR AN AESTHETIC POINT OF VIEW. SPECIFICALLY, THE INVENTION IS DIRECTED TO AND THE USE OF COMPOSITIONS COMPRISING A COMBINATION OF 5-CHLORO-4-PHENYL - 12, - DITHIOLE-3-/NE AND PHENOLIC COMPOUNDS (OR MIXTURES THEREOF). THE INVENTIVE COMPOSITIONS INHIBIT THE GROWTH OF SLIME IN WATER, OR MORE SPECIFICALLY, POSSESS BIOCIDAL ACTIVITY AGAINST BACTERIA, FUNGI AND/OR ALGAE. THE PHENOLIC COMPOUNDS CONTMPLATE FOR USE IN ACCORDANCE WITH THE PRESENT INVENTION ARE THOSE PHENOLIC COMPOUNDS WHICH POSSESS THE CAPACITY TO KILL OR INHIBIT THE GROWTH OF SLIME-FORMING MICROORGANISMS SUCH AS BACTERIA, FUNGI AND ALGAE. THE TYPE PHENOLIC COMPOUNDS ENCOMPASSED BY THE PRESENT INVENTION MAY KBE EXAMPLIFIED BY: PHENOL, ORTHO-PHENYLPHENOL, 2,3,4,6TETRACHLOROPHENOL, 4-CHLORO - 2 - CYCLOPENTYLPHENOL AND 2-CHLORO-4-PHENYLPHENOL.
