TETRABUTYLTIN Usage And Synthesis
Chemical Propertiescolourless liquid
UsesTetrabutyltin, which is used in hydrogenolysis reactions and as a transition metal catalyst.
UsesTetra-n-butyltin is used in hydrogenolysis reactions and as a transition metal catalyst. It is also used stabilizers in the manufacture of polyvinyl chloride.
Flammability and ExplosibilityNotclassified
Safety ProfilePoison by intravenous, intraperitoneal, and parented routes. Moderately toxic by skin contact. An eye irritant. When heated to decomposition it emits acrid smoke and irritating fumes. See also TIN COMPOUNDS.
Purification MethodsDissolve it in Et2O, dry it over MgSO4, filter, evaporate and distil it under reduced pressure. Although it does not crystallise easily, once the melt has crystallised, then it will recrystallise more easily. It is soluble in Et2O, Me2CO, EtOAc and EtOH but insoluble in MeOH and H2O, and shows no apparent reaction with H2O.
