CHEMICAL NAME : Dibutyltin dichloride(DBTC)

FORMULA : C8H18Cl2Sn

CAS NO. : 683-18-1

 

Description:

Dibutyltin dichloride (usually referred to simply as DBTC) is an organotin substance that appears colorless to slightly yellowish-brownish at room temperature. It is readily soluble in organic solvents such as benzene, toluene, ether and alcohols but is very difficult to dissolve in water. Decomposition (hydrolysis) occurs in hot water. Dibutyltin dichloride is flammable, low volatile and has a pungent odor.

Applications:

Produced by reacting tetrabutyltin with tin(IV) chloride, DBTC is a catalyst and stabilizer with a wide range of applications and even acts as a fungicide.

DBTC is a precursor substance from which a number of other tin compounds are made, including products for coating container glass bottles. It serves as a processing aid, process regulator and ion exchanger.As a catalytic active ingredient, it is used in esterification reactions, the production of silicones and polyurethanes, foam plastics, adhesives or sealants.For the modification of synthetic rubbers, DBTC is a reactive process additive that improves the solubility of the soot black additives in the compound. Another area in which DBTC is processed is the light and heat stabilization of PVC plastics. Concentrations between 0.3% and about 3% are common here. End-use applications include, for example, packaging materials or textile products.
