1067-33-0, Dibutyltin diacetate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 6; 221 g of di-n-butyl tin diacetate and 515 g of 2-ethyl-1-butanol (guaranteed reagent, Wako Pure Chemical Industries, Ltd., Japan) were placed in a 2 L volumetric eggplant-shaped flask in a nitrogen atmosphere at atmospheric pressure, and the flask was attached to a rotary evaporator to which was connected an oil bath equipped with a temperature controller, a vacuum pump and a vacuum controller. The purge valve outlet of the rotary evaporator was connected to a line containing nitrogen gas flowing at atmospheric pressure. After replacing the inside of the system with nitrogen, the temperature of the oil bath was set to be 140 C., the flask was immersed in the oil bath and rotation of the rotary evaporator was started. A low boiling point component was distilled off for about 7 hours in the presence of nitrogen at atmospheric pressure with the purge valve of the rotary evaporator left open, after which the pressure in the system was gradually reduced, and residual low boiling point component was distilled off with the pressure inside the system at 76 to 10 kPa. When the low boiling point component fraction no longer appeared, the flask was removed from the oil bath and allowed to cool. 274 g of residual liquid were obtained in the flask. Based on the results of 1H-, 13C- and 119Sn-NMR analyses, the residual liquid in the flask was a solution containing 96.0% by weight of di-n-butyl-bis(2-ethylbutyloxy) tin.On the other hand, 563 g of low boiling point component were recovered. When analyzed by gas chromatography, the low boiling point component contained about 30.9% by weight of (2-ethylbutyl)acetate.
The synthetic route of 1067-33-0 has been constantly updated, and we look forward to future research findings.
