Stannous octoate Usage And Synthesis

Chemical Properties

White or light yellowish brown paste. Soluble in petroleum ether, insoluble in water. low toxicity of Stannous octoate, oral acute poisoning data of rats LD50=3400mg/kg. acute percutaneous poisoning data of rabbits LD50>2000mg/kg.

Uses

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.

Uses

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.

Uses

A catalyst for polylactide polymerization.

Preparation

Stannous 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.

Hazard

Toxic material.

Flammability and Explosibility

Non flammable

Toxicology

Stannous octoate has influence to human health. It may cause an allergic skin reaction, and serious eye damage. In addition, it is suspected of damaging fertility or the unborn child, and harmful to aquatic life with long lasting effects.
