| | Bis(tributyltin) oxide Usage And Synthesis |
| Description | TBTO (bis(tri-n-butyltin)oxide) appears as thin, colourless to pale yellow, flammable and
combustible liquid. It is soluble in organic solvents. TBTO, or bis(tri-n-butyltin)oxide, is an
organotin compound used as a biocide, fungicide, and molluscicide. Uses of tributyltin also
include as an anti-fouling chemical in marine paints for boats, anti-fungal agent in textiles
and industrial water systems, in cooling tower and refrigeration water systems, wood pulp
preservative in paints and paper mill systems, inner surfaces of cardboard, and in the manufacturing
processes of leather goods, textiles, wood, plastics, and mothproof stored garments.
In fact, TBT compounds are considered the most hazardous of all tin compounds. | | Chemical Properties | Clear colorless liquid | | Uses | Bis(tributyltin) Oxide is an organotin compound used as a fungicide and molluscicide, particularly in wood preservation. Bis(tributyltin) Oxide was used as an active component in marine antifouling paints but is not longer used due to its toxicity and is considered a severe marine pollutant. | | Uses | Bis(tributyltin) oxide is widely used in Europe for the preservation of timber, millwork, and wood joinery, eg, window sashes and door frames. It is applied from organic solution by dipping or vacuum impregnation. It imparts resistance to attack by fungi and insects but is not suitable for underground use. An advantage of bis(tributyltin) oxide is that it does not interfere with subsequent painting or decorative staining and does not change the natural color of the wood. | | Uses | Tributyltin oxide is used as an antifouling and biocide
agent against fungi, algae and bacteria in paints and is
an irritant. | | Definition | ChEBI: Tributyltin oxide is an inorganic molecular entity. | | Production Methods | Tributyltin oxide is produced commercially through the controlled reaction of tributyltin chloride with sodium hydroxide or other suitable bases, yielding the oxide form of the organotin compound. Industrial synthesis begins with the preparation of tributyltin chloride from tin metal and butyl halides, followed by hydrolysis under carefully regulated conditions to avoid unwanted side reactions. The resulting tributyltin oxide is purified by distillation or solvent extraction to achieve high chemical quality. | | General Description | Clear pale yellow liquid. Toxic by skin absorption or inhalation of vapors. Used as a bactericide, fungicide and chemical intermediate. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Bis(tributyltin) oxide may react vigorously with oxidizing agents and with reducing agents. | | Hazard | Toxic via ingestion and inhalation. | | Health Hazard | ACUTE/CHRONIC HAZARDS: Bis(tributyltin) oxide is toxic by ingestion and inhalation and is a skin and eye irritant. | | Fire Hazard | Bis(tributyltin) oxide is probably combustible. | | Contact allergens | Tributyl tin oxide is used as an antifouling and biocide
agent against fungi, algae, and bacteria, particularly in
paints. Sometimes used in chemistry, tributyltin oxide is
a strong irritant. | | Mechanism of action | Broad-spectrum, non-systemic, phytotoxic; A metabolic inhibitor with contact and stomach action. | | Pesticide Type | Fungicide; Molluscicide |
