Document Type and Number:
WIPO Patent Application WO/2020/022217
Kind Code:
A1
Abstract:
Provided are: a method for preventing the attachment of a marine organism and others, whereby it becomes possible to keep both of the effects of a halogen agent, e.g., a chlorine disinfectant and a bromine disinfectant, and chlorine dioxide and the effects of an aliphatic quaternary ammonium salt and a N-monosubstituted alkylene diamine for a long period while reducing the use amounts of the halogen agent and chlorine dioxide and also reducing the use amounts of the aliphatic quaternary ammonium salt and the N-monosubstituted alkylene diamine, and it also becomes possible to prevent the attachment of wide varieties of marine organism species and slime; an attachment preventing agent and an attachment preventing kit, each of which can be used for the method. A method for preventing the attachment of a marine organism and slime to a sea water coolant system, the method comprising adding a first chemical agent comprising an aliphatic quaternary ammonium salt represented by general formula (I) and/or a N-monosubstituted alkylene diamine represented by general formula (II) and a second chemical agent comprising at least one component selected from the group consisting of a chlorine disinfectant, a bromine disinfectant and chlorine dioxide to sea water in the sea water coolant system. (In formula (I), R represents a saturated or unsaturated linear aliphatic hydrocarbon group having 10 to 20 carbon atoms; R1 and R3 independently represent an alkyl group having 1 to 4 carbon atoms; R2 represents the same group as R or an alkyl group having 1 to 4 carbon atoms; and X represents Cl, Br, I, a methylsulfate group, an ethylsulfate group or a para-toluenesulfonate group.) R-NH-(CH2)nNH2 (II) (In formula (II), R represents a saturated or unsaturated linear aliphatic hydrocarbon group having 10 to 20 carbon atoms; and n represents an integer of 1 to 4.)
