Stannous octoate
CAS No.301-10-0
Alias: 2-ethyl-hexanoicacitin(2++)salt;STANNOUS 2-ETHYLHEXANOATE;STANNOUS 2-ETHYLHEXOATE;STANNOUS CAPRYLATE;Stannous octanoate;STANNOUS OCTOATE;TIN 2-ETHYL HEXANOATE;TIN 2-ETHYLHEXOATE
Molecular formula: C16H30O4Sn
Relative molecular mass: 405.12
Structural formula:
1. Performance and use:
Stannous 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.
Tin(II) 2-ethylhexanoate is used as a polymerization initiator in polylactic acid production. It acts as an intermediate as well as a catalyst for urethane foams, lubricants, addition agents and stabilizers for transformer oils.
A catalyst for polylactide polymerization.
