Dibutyltin dilaurate

Dibutyltin dilaurate (abbreviated DBTDL), also called dibutyltindilaurate or butynorate, is an organotin compound that is used as a catalyst. It is a colourless oily liquid. In terms of its structure, the molecule consists of two laurate groups attached to a dibutyltin(IV) center.
The molecular geometry at tin is tetrahedral. Based on the crystal structure of the related bis(bromobenzoate), the carbonyl oxygen centers are weakly bonded to tin.
Together with dibutyltin dioctanoate, dibutyltin dilaurate is used as a catalyst for polyurethane production from isocyanates and diols. It is also useful as a catalyst for transesterification and for the room temperature vulcanization of silicones. It is also used as a stabilizer in polyvinyl chloride. It is also added to animal feed to remove cecal worms, roundworms, and tapeworms in turkeys to prevent hexamitosis and coccidiosis.
