1067-33-0, Dibutyltin diacetate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 1; 240 g of di-n-butyl tin diacetate (Aldrich Corp., USA) and 692 g of the bis(3-methylbutyl) carbonate produced in step (A-2) of Reference Example 1 were placed in a 2 L volumetric eggplant-shaped flask in a nitrogen atmosphere at atmospheric pressure, and a Dimroth condenser and three-way valve were attached to the flask. The flask was immersed in an oil bath heated to 150 C. and heated for 5 hours while stirring the contents. 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 150 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. 287 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 92.0% by weight of di-n-butyl-bis(3-methylbutyloxy) tin.On the other hand, 598 g of low boiling point component were recovered. When analyzed by gas chromatography, the low boiling point component contained about 28% by weight of isoamyl acetate.
1067-33-0, As the paragraph descriping shows that 1067-33-0 is playing an increasingly important role.
