General description

Dibutyltin dilaurate, also known as dibutyltin didodecanoate, is a dibutyltin laurate hydroxide intermediate that is commonly used as a catalyst. It is also used in the transesterification reaction.

Application

Dibutyltin dilaurate is used as a catalyst in:
  • The synthesis of polyurethane (PU) and polyhydroxyurethane (PHU) prepolymers and lignin urethane.
  • A protocol for the covalent attachment of poly(ethylene glycol) (PEG) to silicon oxide to form a hydrophilic non-fouling surface.
  • Preparation of polymers by reacting hydroxyl-terminated macromonomers and aliphatic diisocyanates.
