دی بوتیل تین دیلايورات
Dibutyltin dilaurate (DBTDL) 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.[1]
Together with dibutyltin dioctanoate, DBTDL 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 PVC
