1.3 Synthetic Route
Properties of Dibutyltin Oxide
Dibutyltin oxide is light yellow or white crystalline powder, which decomposes directly at 350°C. It is insoluble in water and most organic solvents, but it may be dissolved in organic acids and esters, soluble in dilute hydrochloric acid and acetic acid.
The use of dibutyltin oxide
Dibutyl tin oxide is used in automotive and industrial water-based polyurethane electrophoretic paints. It is a very effective catalyst for transesterification reactions and is used in the production of resins for coatings that require high-temperature transesterification reactions. It is one of the intermediates for synthesizing organotin. It is used in PVC heat stabilizers, SPC self-polishing marine antifouling coatings, wood preservation, agricultural fungicides, glass treatment and organic synthesis.
