Paragraph 0013, (2017/07/04)
The invention discloses a method for synthesizing loosened mono-butyl tin-oxide. The method comprises the following steps: slowly adding mono-n-butyltin trichloride into a reaction kettle with alkaline liquor in a certain proportion under a constant temperature; adding prepared additives in batches in a constant-temperature reaction process; performing water washing twice after the reaction is completed; after a mono-n-butyltin trichloride product is qualified after the water washing, slowly transferring the mono-n-butyltin trichloride product into a centrifugal machine for performing centrifuging; collecting centrifuged materials, and transferring the centrifuged materials into a vacuum drying machine for drying to prepare the mono-n-butyltin trichloride product. According to the method, the additives are added into the reaction, so that the product is loosen and is easily dewatered; the water washing efficiency is greatly improved; production waste water is reduced.
