A process for the fractional production of mono-, di- or triorganotin oxides which comprises subjecting an organotin halide to hydrolysis, separating the hydrolysis reaction mixture into three layers, and thereby obtaining the desired organotin oxide-containing layer as a triorganotin oxide-containing layer substantially free of mono- and/or diorganotin oxide, a monoorganotin oxide-containing aqueous layer, or a diorganotin oxide-containing layer substantially free of mono- and/or triorganotin oxide, and then recovering the tri-, mono- or diorganotin oxides from the desired organotin oxide-containing layers.
一种用于分级生产单、二或三有机锡氧化物的方法,包括将有机锡卤化物进行水解,将水解反应混合物分离成三层,从而获得所需的含有三有机锡氧化物的层,该层基本上不含有单和/或二有机锡氧化物,含有单有机锡氧化物的水层,或基本上不含有单和/或三有机锡氧化物的含有二有机锡氧化物的层,然后从所需的有机锡氧化物层中回收三、单或二有机锡氧化物。
