More Information
Summary:The invention discloses a treatment method of dibutyltin oxide and application of the treatment method to synthesis of cane sugar-6-ethyl ester. The treatment method comprises the steps of adding the water-containing dibutyltin oxide to nonpolar solvent containing DMF, and heating the mixture for azeotropic water removal, so that low-water-content dibutyltin oxide is obtained after the process is ended. The mass percentage of water in the low-water-content dibutyltin oxide is 0.6% and below. The treatment method is safe, easy to operate and good in dehydration effect, the dibutyltin oxide is not prone to damage and loss in the recycling process, the recycling rate is high, purity is high, the method can be directly applied to production of cane sugar-6-ethyl ester, meanwhile, harm and potential safety hazards caused to human bodies and the environment in the dibutyltin oxide shifting process are avoided, and the treatment method is quite suitable for industrialized production.
