Tin Tetra-ethyl, Sn(C2H5)4, prepared from zinc ethyl arid stannous chloride, according to the following reaction:
2SnCl2 + 4Zn(C2H5)2 = Sn(C2H5)4 + Sn + 4Zn(C2H5)Cl,
is a combustible liquid having a density of 1-187 at 23° C.; it is insoluble in water and boils at 181° C. Tin tri-ethyl iodide, Sn(C2H5)3I, exists, to which there correspond an oxide, hydroxide, and various salts; likewise the di-ethyl di-iodide, Sn(C2H5)2I2, and salts such as sulphate, nitrate, acetate. The ethyl stannic compounds resemble those of methyl described above. |
