With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1067-33-0,Dibutyltin diacetate,as a common compound, the synthetic route is as follows.

[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 140C, 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., 1067-33-0

As the paragraph descriping shows that 1067-33-0 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1067-33-0,Dibutyltin diacetate,as a common compound, the synthetic route is as follows.

[Example 7] 306 g of a residual liquid were obtained by carrying out the same method as Example 6 with the exception of using 255 g of di-n-butyl tin diacetate, and using 961 g of 3-methyl-1-butanol (Tokyo Chemical Industry Co., Ltd., Japan) instead of 2-ethyl-1-butanol. The residual liquid contained 92.7% by weight of di-n-butyl-bis(3-methylbutyloxy) tin. In addition, the low boiling point component contained 18.0% by weight of isoamyl acetate.

The synthetic route of 1067-33-0 has been constantly updated, and we look forward to future research findings.

1067-33-0, Dibutyltin diacetate is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Example 11; 289 g of di-n-butyl tin diacetate and 1024 g of bis(2-ethylbutyl) carbonate 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 280 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. 365 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 79.7% by weight of di-n-butyl-bis(2-ethylbutyloxy) tin and 7.6% by weight of tri-n-butyl-(2-ethylbutyloxy) tin.On the other hand, 888 g of low boiling point component were recovered. When analyzed by gas chromatography, the low boiling point component contained about 25.2% by weight of (2-ethylbutyl)acetate.

1067-33-0 Dibutyltin diacetate 16682740, acatalyst-ligand compound, is more and more widely used in various.
