Chemical Properties
Dibutyltin oxide (Bu2SnO, C8H18OSn, CAS registry No. 818-08-6) is a white fine powder. Its flash point is 81-83 °C. The solubility of HNQ is 4.0 mg/L in water at 20 °C. It is flammable when exposed to flame. It can react with oxidizing materials. To fight fire, use dry chemical, fog, CO2. When heated to decomposition, it emits acrid smoke and irritating fumes.
Uses
Dibutyltin oxide can be used as the catalyst in organic reaction.

COMPOUNDS.
Purification Methods
It is prepared by hydrolysis of di-n-butyltin dichloride with KOH. Hence wash it with a little aqueous M KOH, then H2O and dry at ~80o/10mm until the IR is free from OH bands. [Cummings Aust J Chem 18 98 1965, Beilstein 4 I 588.]
