PURPOSE:To obtain the title controller containing 2-n-octyl-4-isothiazolone and 2,3,5,6-tetrachloro-4-(methylsulfonyl)pyridine showing inhibitory effects on growth of molds, main part of slime. CONSTITUTION:A slime controller containing 2-n-octyl-4-isothiazolone and 2,3,5,6- tatrachloro-4-(methylsulfonyl)pyridine as active ingredients, having extremely inhibitory effects on growth of molds, main part of slime, not changing qualities of fuel, readily soluble in fuel, soluble in water at the interface of water base. The blending ratio of the two compounds is 0.1-5, preferably 0.2-1pt.wt. of the latter based on 1pt.wt. of the former. The content ratio of the active ingredients is about 1-30wt.%, preferably 10-30wt.%. The amount of the controller added to heavy oil, gasoline, kerosine, jet fuel, etc. is 50-10,000ppm, especially about 100-5,000ppm. |
