SnOct2

SnOct2, also known as tin(II) octanoate, is an organotin compound with the formula Sn(C8H15COO)2. It features a tin(II) center coordinated by two octanoate ligands. In solution or solid form it can exist as discrete units or in polymeric/dimeric structures depending on conditions.

Preparation of SnOct2 typically involves reacting tin(II) salts (such as tin(II) chloride or tin(II) oxide) with octanoic acid under suitable conditions, followed by purification to remove inorganic byproducts. It is often encountered as a colorless to pale yellow solid or viscous liquid that is soluble in many organic solvents and sensitive to moisture.

Applications for SnOct2 center on catalysis and stabilization. It is widely used as a catalyst in polyurethane production, including the curing of polyurethanes and related coatings, elastomers, and adhesives. In addition, tin(II) octanoate is employed as a heat stabilizer or secondary stabilizer in vinyl chloride polymers (PVC) and can participate in various esterification or transesterification processes as a catalyst.

Safety and handling considerations are important due to its status as an organotin compound. SnOct2 can be toxic to aquatic life and may pose health hazards upon exposure, so work should be conducted with appropriate personal protective equipment, adequate ventilation, and proper containment. It should be stored away from moisture and incompatible substances, with waste disposed as hazardous chemical waste in accordance with regulatory requirements.
