YieldReaction ConditionsOperation in experiment
at 113℃; for 12h;Heating / reflux; Using a device as shown in Fig. 3, dioctyltin dialkoxides were produced as follows. Into a 5-liter SUS reaction vessel 1 equipped with a stirrer, a heater and a baffle were charged 108 g (0.3 mol) of dioctyltin oxide and 2,223 g (30 mol) of 1-butanol (manufactured and sold by Aldrich, U.S.A.), wherein dioctyltin oxide was fed through conduit 4 provided at the top of reaction vessel 1, and 1-butanol was fed from alcohol reservoir 16 through conduit 3 provided at an upper portion of reaction vessel 1. Further, nitrogen gas was fed to reaction vessel 1 through a SUS tube connected to inert gas conduit 2 provided at a lower portion of reaction vessel 1 at a rate of 0.5 N/hr. Subsequently, the contents of reaction vessel 1 were heated while stirring, so as to adjust the temperature thereof within the range of from 113 C to the boiling point of 1-butanol, thereby performing a reaction for about 12 hours while discharging low boiling point components in the form of a gas through gas discharging conduit 5 provided at an upper portion of reaction vessel 1. During the reaction, the gas discharged from conduit 5 was transferred through condenser 6 to reservoir 7 in which a liquid mixture containing 1-butanol and water was obtained. After the reaction, the resultant liquid reaction mixture in reaction vessel 1 was withdrawn from withdrawal conduit 8 and transferred to reservoir 9. From reservoir 9, the liquid reaction mixture was transferred through conduit 10 to apparatus 11 for removing alcohol, which was equipped with a stirrer, a pressure-reduction device and a heater. The above-mentioned operation was repeated two times (i.e., the above-mentioned operation was performed three times in total). Then, the liquid reaction mixture collected in apparatus 11 for removing alcohol was heated under reduced pressure to thereby gasify the unreacted alcohol contained in the liquid reaction mixture. The gasified alcohol was discharged from conduit 21, and transferred through condenser 6 to reservoir 16. The residual liquid having the alcohol removed therefrom was discharged from apparatus 11 and transferred through conduit 12 to reservoir 23. The liquid obtained in reservoir 23 was analyzed. As a result, it was found that the weight of the liquid was about 375 g, and that the liquid contained about 0.50 mol of dioctyltin dibutoxide and about 0.20 mol of 1,1,3,3-tetraoctyl-1,3-dibutyloxydistannoxane.

At the end of six hours, any remaining xylene is removed by distillation under vacuum. The crude yellow oil obtained is chromatographed through a pad of silica gel using ethyl aetate as the eluent. The title compound is obtained in a 70% yield as a low melting yellow solid, melting at 45-52 C., whose structure is consistent with 1Hnmr and mass spectrometry.
