Bis(tributyltin) oxide Chemical Properties,Uses,Production

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.

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.
