Procedure
A reaction mixture of monobutyltin trichloride (200 g., 0.7 moles) and the sodium salt of trifluoroacetic acid (10 g., 0.07 moles) were heated at 70° C. for 3 hours and allowed to stand overnight at room temperature. The sodium chloride by-product and unreacted sodium salt were filtered. A liquid coating composition of about 12 wt.% monobutyldichlorotin trifluoroacetate and 88 wt% monobutyltin trichloride was produced in situ.
