MYCLOBU탄IL C화학적 특성, 용도, 생산

개요

Myclobutanil is a broad-spectrum systemic foliar-applied fungicide of the substituted triazole chemical class of compounds, with protective, eradicative, and curative action. It disrupts membrane function in fungi by inhibition of sterol biosynthesis.
It is produced by the alkylation of 4-chlorophenylacetonitrile with butyl chloride, followed by treatment with dibromomethane and sodium hydroxide in dimethyl sulfoxide. The resulting intermediate is then reacted with the potassium salt of 1,2,4-triazole in dimethyl formamide.
Commercially, myclobutanil is presented as different formulations or preparations with concentrations up to 60% active ingredient (a.i.). It is formulated as a wettable powder (2–40% a.i.) or as an emulsifiable concentrate (1–25% a.i.), granular (<1% a.i.), dust (5% a.i.), dry flowable (60% a.i.), and ready to use (<1% a.i.) solutions to be used in agriculture or in domestic activities by homeowners.
It is also used at lower concentrations in combination with other agrochemicals such as pyretroids (permethrin), fludioxonil, mefenoxam, azoxistrobin, mancozeb, sulfur, or fluoxastrobin.

화학적 성질

White to pale yellow crystalline solid. Soluble in alcohols, aromatics, esters, ketones and other organic solvents. Solubility is about 50-100g/L; insoluble in aliphatic hydrocarbons such as hexane; solubility in water is 142mg/L. The degradation half-life is 25 days in aqueous solution under sunlight, and 66 days in soil. It does not degrade under anaerobic conditions, and does not hydrolyze within 28 days under the conditions of pH 5, 7, and 9 (28°C).

용도

Myclobutanil is an fungicide used on a wide range of food crops. Myclobutanil inhibits the biosynthesis of ergosterol, a critical componet of fungal cell membranes.

잠재적 노출

Myclobutanil is a nitrile compound and a triazole fungicide. It is widely used to control powdery mildew, rust, sclerotina, spot blight, rot, black rot and similar fungi on a variety of food and nonfood crops. Nitriles can be derived from salts of cyanide, but are usually less toxic.

Relevant physicochemical properties are estimated Koc value of 950, log Kow of 2.94, estimated Henry’s law constant of 4.3×10^-9 atmm³ mol^-1 at 25 ℃, vapor pressure of 1.6
106 mmHg, and water solubility of 140 mg l^-1.
In soil under aerobic conditions, myclobutanil exhibits high to very high persistence, and medium to low mobility, forming the minor soil metabolite myclobutanil butyric acid which exhibits low to moderate persistence and very high mobility in soil. Both adsorptions are affected significantly by differing soil pH. Volatilization from moist soil surfaces is not expected to be an important fate process. The biodegradation half-life of myclobutanil in silt loam soil is about 66 days. No degradation was observed under anaerobic conditions.
In aquatic environments, it is expected to adsorb to suspended solids and sediment. Volatilization from water surfaces is not expected. In dark natural sediment water systems, myclobutanil partitioned from the water column to sediment, where it exhibited very high persistence. Aqueous solutions of myclobutanil decompose on exposure to light with half-lives of 222 days in sterile water, 0.8 days in sensitized sterile water, and 25 days in pond water. Hydrolysis was not observed after 28 days at pH values of 5, 7, and 9 at 28 ℃.
An estimated bioconcentration factor of 37 suggests the potential for bioconcentration in aquatic organisms is moderate, provided the compound is not metabolized by the organism.
In the ambient atmosphere, it is expected to exist in both the vapor and particulate phases. Vapor-phase myclobutanil is degraded by reaction with photochemically produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.3 days. Particulate-phase myclobutanil may be removed from the air by wet or dry deposition.

신진 대사 경로

There is limited published information available on the metabolism of myclobutanil. In plants and mammals, the butyl group is oxidised to an alcohol and a ketone. In soils, substantial degradation of the molecule occurs under aerobic conditions.

비 호환성

Decomposes on exposure to strong light. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. The triazoles are sensitive to heat, friction, and impact. Sensitivity varies with the type substitution to the triazole ring. Metal chelated and halogen substitution of the triazole ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives. Nitriles may polymerize in the presence of metals and some metal compounds. They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Nitriles are generally incompatible with other oxidizing agents such as peroxides and epoxides. The combination of bases and nitriles can produce hydrogen cyanide. Nitriles are hydrolyzed in both aqueous acid and base to give carboxylic acids (or salts of carboxylic acids). These reactions generate heat. Peroxides convert nitriles to amides. Nitriles can react vigorously with reducing agents. Acetonitrile and propionitrile are soluble in water, but nitriles higher than propionitrile have low aqueous solubility. They are also insoluble in aqueous acids.

폐기물 처리

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Contact a licensed disposal facility about surplus and nonrecyclable solutions. Burn in a chemical incinerator equipped with an afterburner and scrubber. Extra care must be exercised as the material in an organic solvent is highly flammable. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Incineration or permanganate oxidation.
