Dioctyltin oxide Usage And Synthesis
Chemical Propertieswhite to almost white crystalline powder. It is practically insoluble in water but soluble in organic solvents.
UsesDioctyltin oxide is used as a stabilizer and as a widely applicable catalyst, especially for esterification reactions, transesterification reactions and condensation reactions. It is slightly less reactive than dibutyltin oxide, but is not subject to as many regulatory restrictions, which is why it is increasingly used. Dioctyloxotin can also be used in various chemical synthesis such as in preparation of trinuclear seven-coordinated tin complexes, having possible antioxidant, and anti-inflammatory activity.
ApplicationAmorphous white solid available in various particle sizes with several uses:
widespread use in the aqueous cathodic electrodeposition of urethane coatings for automotive and industrial applications
active transesterification catalyst for methacrylate esters that are used in the water treatment market
high temperature transesterification reactions for the production of coating resins and specialty monomeric esters
intermediate for heat stabilizers
Flammability and ExplosibilityNonflammable
Safety ProfileModerately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes. See also TIN COMPOUNDS.
