TIN(IV) ACETATE Chemical Properties,Usage,Production

Chemical Properties

TIN(IV) ACETATE is a white, crystalline substance; very moisture sensitive. M.p. 253℃. Hydrolyzes in water to stannic and acetic acids; quite soluble in benzene and acetone, moderately soluble in CCl4.

Uses

Tin(IV) acetate is used to prepare tin-based oxides (Sn-Zn-P-O), which is a negative electrodes for rechargeable lithium batteries.

Preparation

The reaction of TIN(IV) ACETATE requires exclusion of moisture. It proceeds in a 150ml three-neck ground glass flask which is equipped with a mercury-seal stirrer, a straight, ground glass filling tube, and a reflux condenser with a drying tube. The flask is filled with a suspension of 16.8 g of TICH3COO in 100 ml. of pure acetic anhydride and 10 g. of Snl4 is added by portions with constant, vigorous stirring. The stopper on the filling tube should stay in place except for the actual short addition time. The reaction starts immediately and the yellow, sparingly soluble Til settles out. After the addition, vigorous stirring is continued for 1.5 hours at 80℃ and for 0.5 hour at room temperature. The Til is then rapidly suction-filtered with exclusion of moisture. The filtrate is concentrated to about 50 ml. with moderate heating at 20 mm. (keep out moisture). On cooling, a precipitate of white needles of Sn(CH3COO)4 is obtained. This is filtered in the absence of moisture, washed with anhydrous ether and finally dried in vacuum. Further concentration of the yellow-orange mother liquor yields an additional pale yellow fraction of the salt which may be further purified by recrystallization from acetic anhydride if necessary. The yield is practically quantitative.
