[0027] It should be noted that the alcohol-water separation tank for the chemical preparation of polyol esters is equipped with a feeding and stirring component, which can quantitatively feed a promoter into the generated butanol water vapor to accelerate the efficiency of alcohol-water separation. Through the coordinated action of the driving motor 3, the rotating rod 4 and the stirring blade 5, the promoter and the butanol water vapor can fully react, thereby improving the use quality of the device.

[0028] Specifically, when the alcohol-water separation tank for the chemical preparation of polyol esters is used, butanol water vapor is fed into the tank body 1 through the liquid inlet pipe 10, and then the promoter is quantitatively fed into the tank body 1 from the feeding pipe 8, and at the same time, the driving motor 3 is started through the control panel 14 to drive the rotating rod 4 to rotate, so that the stirring blade 5 rotates, and the promoter and the butanol water vapor are fully mixed, and then flow into the installation box 11 through the discharge pipe 7 for static stratification, thereby improving the efficiency of stratification, and the scraper 6 can scrape off the residual liquid on the partition plate 2, thereby improving the use quality of the device.
