Tin(II) 2-ethylhexanoate or tin(II) octoate or stannous octoate (Sn(Oct)
2) is a compound of tin. Produced by the reaction of
tin(II) oxide and
2-ethylhexanoic acid
2-Ethylhexanoic acid is the organic compound with the formula CH3(CH2)3CH(C2H5)CO2H. It is a carboxylic acid that is widely used to prepare lipophilic metal derivatives that are soluble in nonpolar organic solvents. 2-Ethylhexanoic acid is a colo ...
, it is a clear colorless liquid at room temperature, though often appears yellow due to impurities, likely resulting from oxidation of Sn(II) to Sn(IV).
It is sometimes used as a
catalyst for
ring-opening polymerization, such as for the production of
polylactic acid
Polylactic acid, also known as poly(lactic acid) or polylactide (PLA), is a thermoplastic polyester with backbone formula or , formally obtained by condensation of lactic acid with loss of water (hence its name). It can also be prepared by rin ...
