Procedure

Although 1,1,3,3-tetra-n-octyl-1,3-bis(3-methylbutyloxy)distannoxane was obtained by reacting di-n-octyl-diacetoxy tin and aqueous alkaline solution (aqueous potassium hydroxide solution) instead of directly reacting the di-n-octyl-diacetoxy tin obtained in step (I-2) with 3-methyl-1-butanol in step (I-3) to obtain dioctyl tin oxide, followed by reacting the dioctyl tin oxide with 3-methyl-1-butanol, since the dioctyl tin oxide was a solid thereby requiring the procedure of recovering the solid by filtration, the procedure is excessively complex in terms of industrial application.
