Compositions and their use as slime control agents
Abstract
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 MANUFATURE OF PULP PAPER AND WATER EMPLOYED IN COOLING WATER SYSTEM AS WELL AS OTHER INDUSTRIAL WATERS, PROVIDE ENVIRONMENTS WHICH ARE CONDUCTIVE TO SLIME FORMATION. THE NOVEL COMPOSITIONS OF THE PRESENT INVENTION ARE MIXTURES WHICH SHOW UNEXPECTED SYNEGISTIC ACTIVITY AGAINST MICROORGANISM, INCUDING 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 - TETRACHLOROTETAHYDROTHIOPHENE - 1,1 - DIOXIDE AND ORGANO - BROMINE COMPOUNDS (OR MIXTURE THEREOF). THE INVENTIVE COMPOSITIONS INHIBIT THE GROWTH OF SLIME IN WATER, OR MORE SPECIFICALLY, POSSESS BIOCIDAL ACTIVITY AGAINST BACTERIA FUNGI AND/OR ALGAE. THE ORANGO-BROMINE COMPOUNDS CONTEMPLATED FOR USE IN ACCORDANCE WITH THE PRESENT INVENTION MAY BE EXEMPLIFIED BY: BIS - 1,4 - BROMOACETOX - 2 - BUTENEE; ALPHA-BROMO-PMETHYLACETOPHENONE AND BETA-BROMO-BETA-NITROSTYRENE.
