Role of Dioctyltin Oxide as a Catalyst

Organotin stabilisers mainly include the following types: Aliphatic acid salts: for example, dibutyltin dilaurate, di-n-octyltin dilaurate, and so on. The tin atoms in this type of stabiliser can be coordinated with the chlorine atoms on the PVC molecular chain and inhibit the reaction of removing HCl through the replacement reaction, thus playing a stabilising role.…
