[0005] However, due to the long application time of the existing fungicides and the high resistance of bacteria to them, the purpose of controlling microbial corrosion in water has not been achieved. At present, there is an urgent need for a fungicide that can protect oilfield water systems, industrial circulating water, and urban pipe networks. Harmful bacteria in the sewage system, such as sulfate-reducing bacteria, saprophytic bacteria, and iron bacteria, are new products with high-efficiency killing effects

Embodiment 1
[0024] Pyridine and 9-chloromethylanthracene were reacted at 130°C for 3 hours at a molar ratio of 1:1 to obtain N-(9-anthracenemethyl)pyridine chloride (compound 1). Elemental analysis: C, 78.55; H , 5.27; Cl, 11.59; N, 4.58.
[0025] Add N-(9-anthracenemethyl)pyridine chloride, dithiocyanomethane, formaldehyde, and Tween-80 into isopropanol in a mass ratio of 13:18:12:5, and isopropanol accounts for 1% of the total mass. 52%, obtain fungicide product A after stirring.
Embodiment 2
[0027] 2,4 lutidine and 9-chloromethyl anthracene were reacted at 140°C for 3 hours in a molar ratio of 1:11 to obtain N-(9-anthracenemethyl)lutidine chloride (compound 2 ) Elemental analysis: C, 79.15; H, 6.04; Cl, 10.62; N, 4.20.
[0028] Add N-(9-anthracenemethyl)lutidine chloride, formaldehyde, dimethylformamide, and Tween-20 into water in a mass ratio of 20:5:10:4, and water accounts for 61% of the total mass , to obtain fungicide product B after stirring.
Embodiment 3
[0030] 2,4,6 collidine, 9-chloromethyl anthracene, molar ratio 1: 1.5, reacted at 180°C for 6 hours to obtain N-(9-anthracene methyl) collidine chloride (compound 3) Elemental analysis: C, 79.41; H, 6.37; Cl, 10.19; N, 4.03.
[0031] Add N-(9-anthracenemethyl)collidine chloride, dithiocyanomethane, formaldehyde, and Tween-20 into isopropanol in a mass ratio of 30:8:5:5, and isopropanol accounts for 52% of the total mass, after being stirred evenly, fungicide product C is obtained.

Abstract
The invention provides an application of a pyridines compound shown as a general formula (I) in the specification, to preparation of a bactericide, wherein R is H or a methyl, and n is 1,2 or 3. The invention also relates to an application of the composition which takes the compound as a main effective ingredient to preparation of the bactericide. The bactericide has efficient action on killing harmful bacteria, such as sulfate reducing bacteria, saprophyte and iron bacteria in an oil field water system, industrial cycling water and urban pipe network sewage systems to reach a bacteria amount control standard in oil filed injected water and cycling water.
Description
technical field [0001] The invention belongs to the technical field of metal anticorrosion, and relates to the application of a pyridine compound as a fungicide, in particular to the application of N-(9-anthracenemethyl)R-pyridine quaternary ammonium chloride in the preparation of a fungicide. The chlorinated N-(9-anthracenemethyl)R-pyridine quaternary ammonium salt can be used for controlling microbial corrosion in oil field collection, transportation and water injection systems and industrial circulating water. Background technique [0002] In the oilfield water injection system, the presence of microorganisms can cause pipeline corrosion and damage and blockage of oil layers and pipelines, resulting in a decrease in water injection rate and affecting oil recovery. At the same time, microorganisms can also cause degradation of polymers used in tertiary oil recovery, resulting in huge economic losses. More than 77% of the corrosion in production oil wells in the United Stat...
