Chemie und Industrie
Anwendungen
VerwendenStannous octoate is susceptible to hydrolysis and oxidation and cannot be used in combination polyethers (premixes). Its catalytic activity is higher than that of dibutyltin dilaurate.Stannous octoate can be used as a catalyst for polyurethane, mainly in the production of soft block polyether type polyurethane foam, but also as a catalyst for polyurethane coatings, elastomers, room temperature curing silicone rubber, etc. As it is a divalent tin compound, it may be oxidized to tetravalent tin compound itself after foaming, and it remains in the foam body to play the role of an antioxidant, which stays in the foam after foaming and has no adverse effect on the foam performance.
Darstellung
synthetischeStannous octoate is produced by reacting 2-ethylhexanoic acid with sodium hydroxide to form sodium 2-ethylhexanoate, which then undergoes a complex decomposition reaction with stannous chloride by heating in an inert solvent.
