application | monobutyl tin oxide is mainly used as a catalyst for the production of saturated polyester resins such as powder coatings, coil (steel) coatings, insulating paints, and unsaturated polyester resins. Used as plastic stabilizer raw materials, organotin intermediates, esterification reaction catalysts, electrophoretic electrodeposition coating catalysts. |
preparation | weigh 12gNa2CO3 into a reaction bottle and stir and dissolve it with 200g of water, add 200g of ammonia water with a concentration of 20% to put the reaction bottle into a water bath and raise the temperature to 50 ℃; Weigh 1g of additive, dilute with 20g of water, take 50% and add it to the reaction bottle; Weigh 100g of monobutyltin trichloride liquid, put it into a constant pressure funnel and slowly drop it into the reaction bottle, constant temperature reaction for 2h. The diluted additive 20% is added every 30 minutes during the constant temperature process. After the reaction is over, the mono-butyl tin oxide obtained from the reaction is filtered by a cloth funnel, the filter cake is transferred into a 500Ml beaker and about 200ml of water is added for washing, the washing temperature is controlled at 50-60 ℃, and the filter cake is filtered by suction after repeated twice. the obtained filter cake is dried by a rotary evaporator at a drying temperature of 70-80 ℃, and finally 70.78g mono-butyl tin oxide product is obtained with a yield of 99.1%. |
