Chemical name: Dioctyltin Oxide
CAS number: 870-08-6
Description and features
Dioctyltin Oxide (ViaCat DOTO) is an white powder which has C16H34OSn as chemical formula. It finds its application in aqueous cathodic electrodeposition of urethane coatings for automotive and industrial applications. Further it is an active transesterification catalyst for methacrylate esters that are used in the water treatment market. Besides, DOTO is used in select high temperature transesterification reactions for the production of coating resins and specialty monomeric esters. Lastly, it is being used as intermediate for producing dioctyltin compounds, especially PVC heat stabilizers.
Dioctyltin Oxide is also known as di-n-octyltin oxide, dioctyloxostannane and oxodioctylstannane.
