Tin(II) 2-ethylhexanoate or tin(II) octoate or stannous octoate (Sn(Oct) 2) [1] is a compound of tin. Produced by the reaction of tin(II) oxide and 2-ethylhexanoic acid, 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).
2-Ethylhexanoic acid (2-EHA), commonly known as octoic acid, [2] is the organic compound with the formula CH 3 (CH 2) 3 CH(C 2 H 5)CO 2 H. 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 colorless viscous oil. It is supplied as a racemic ...
acid-base reactions: L n MOR' + RCO 2 H → L n MO 2 CR + R'OH protonolysis: L n Malkyl + RCO 2 H → L n MO 2 CR + alkane oxidative addition: L n M + RCO 2 H → L n (H)MO 2 CR. From preformed carboxylate, salt metathesis reactions are common: L n MCl + RCO 2 Na → L n MO 2 CR + NaCl. Metal carboxylates can be prepared by carbonation of ...
One of the anti-corrosion components presented as sodium or potassium 2-ethylhexanoate and ethylhexanoic acid is incompatible with nylon 6,6 and silicone rubber, and is a known plasticizer. Class action lawsuits were registered in several states of the US, and in Canada, [27] to address some of these claims.
This reaction is an important approach to the formation of carbon-carbon bonds in organic molecules containing ring systems. As an example, under strong basic conditions (e.g. sodium hydroxide), hexane-2,5-dione (compound A in Figure 1) can cyclize via intramolecular aldol reaction to form the 3-methylcyclopent-2-en-1-one (compound B).

2 ONa. In practice, considerable sodium is consumed by the formation of hydrogen. [citation needed] For this reason, an excess of sodium is often required. Because the hydrolysis of sodium is rapid, not to mention dangerous, the Bouveault-Blanc reaction requires anhydrous ethanol and can give low yields with insufficiently dry ethanol.
Common catalysts used in the preparation of this polymer include tin(II) 2-ethylhexanoate, tin(II) alkoxides, or aluminum isopropoxide. During polymerization, successive monomeric units (of glycolic or lactic acid) are linked together in PLGA by ester linkages, thus yielding a linear, aliphatic polyester as a product.
