Fenbutatin oxide Usage And Synthesis
Chemical PropertiesWhite crystalline solid or powder. Mild odor
UsesFenbutatin Oxide is an organotin pesticide. Fenbutatin Oxide is widely used as an aracacide in the control of mites, in particular spider mites.
UsesAcaricide.
UsesFenbutatin oxide is a non-systemic acaricide used to control a wide range of phytophagous mites on deciduous fruits, citrus, vines, selected nut crops, bananas, glasshouse crops and ornamentals.
DefinitionChEBI: Fenbutatin oxide is an organotin acaricide.
General DescriptionWhite crystalline solid with a mild odor.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileFenbutatin oxide is in the family of tin compounds widely used as stabilizers for plastics, additives to paint(as antifouling agents). Some have catalytic properties. Examples include butyl tin, dibutyl tin oxide. Their main hazard is associated with their high toxicity, in skin adsorption or inhalation.
Agricultural UsesInsecticide, Miticide: A U.S. EPA restricted Use Pesticide (RUP). A selective miticide for deciduous pome and stone fruits, citrus fruits, grapes, vegetables, berry fruit, nut crops (selected), ornamentals and greenhouse crops.
Trade nameBENDEX®; NEOSTANOX®; OSDARAN®; SD-14114®; SHELL SD-14114®; TORQUE®; VENDEX®
Potential ExposureOrganotin/phenyltin insecticide and selective miticide for deciduous pome and stone fruits, citrus fruits, grapes, vegetables, berry fruit, nut crops (selected), ornamentals, and greenhouse crops. A United States Environmental Protection Agency Restricted Use Pesticide (RUP)
Environmental FateChemical/Physical. Reacts with moisture forming tris(2-methyl-2-phenylpropyl)tin hydroxide (Worthing and Hance, 1991).
Metabolic pathwayFenbutatin oxide is quite stable to hydrolytic degradation. Metabolism in soils, plants and animals is minimal. The extensive and irreversible adsorption/binding to cationic and organic matter is the primary dissipation mechanism in the soil environment. Cleavage of the neophenyl-tin linkages is the primary degradation and metabolic pathway (Scheme 1). Transformation of the neophenyl moiety has not been observed. Most of the information reported below was obtained from experiments using 119mSlna belhg conducted by DuPont.

DegradationFenbutatin oxide (1) dissociates slowly in water to the corresponding hydroxide [tris(2-methyl-2-phenylpropyl)tin hydroxide 21. The neophenyl moiety of fenbutatin oxide was stable at pH 5, 7, and 9 at 25 °C with minimal degradation occurring after 30 days (Home, 1987a).
The photodegradation of fenbutatin oxide in pH 7 buffer solution was a significant degradation process with a DT50 of approximately 51 days following continuous exposure to simulated sunlight at 25 °C (Home, 1987b). Fenbutatin oxide underwent hydrolysis with a loss of two moles of the 2-methyl-2-phenylprop yl moiety, yielding dlhydroxy-bis(2-methyl- 2-phenylpropyl)stannane (3), accounting for ca. 23% of the initial concentration after 15 days of continuous irradiation. Fenbutatin oxide and its metabolites react reversibly with water to form the analogous oxide/hydroxide compounds (Gray et a1 ., 1995).
IncompatibilitiesMay form explosive mixture with air. Decomposes above 230C. Contact with water causes slow decomposition. Orgotin oxides can be strongly basic and will react, possibly dangerously, with acidic compounds and mixtures
Waste DisposalOrganic tin compounds may be disposed of in sealed containers in secured sanitary landfill. Chemical Treatability of tin; Concentration Process: Chemical precipitation; Chemical Classification: Metals; Scale of Study: Pilot scale; Type of Wastewater Used: Synthetic wastewater; Results of Study: At 600 ppm, 95.3% reduction with alum. At 500 ppm, 98% reduction with ferric chloride, 92% reduction with lime (three coagulants used: 200 mg of alum at pH = 6.4, 40 ppm of ferric chloride @ pH = 6.2, 41 ppm of lime @ pH = 11.5 Chemical coagulation was followed by dual media filtration). Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. 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.
