1.CMIT/MIT is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics etc.

2.When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. No used together with oxidative fungicidal such as chlorine, and no used in cooling water system containing sulfur.

3.When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.

4.Use It is used to treat industrial circulating water and functions as a germicide and algae killer. It is a widely used bactericidal antiseptic that can effectively kill algae, bacteria and fungi. The active single agent can be widely used in industries such as industrial cooling water, oil field return water, paper industry, pipeline, paint, paint, rubber and cosmetics, photographic film and detergents. Effective use, less toxic, non-polluting, easy to mix in various formulations, PH use a wide range, after dilution of the concentration, it is easily biodegradable into non-toxic pollution-free substances.

5.Use Angiotensin converting enzyme inhibitors, prodrugs, for hypertension.

6.Use Fungicides are widely used in industrial water treatment, swimming pool water treatment, etc.
