Reaction Conditions:
in water at 60; for 2.5 h;Temperature;
Steps:
3 Experimental Example 3:
11 g of Na2CO3 was weighed into a reaction flask and stirred with 200 g of water,Add 200g of ammonia concentration of 20% of the reaction flask into the water bath to 60 ; weighing 0.9g additives diluted with 20g water after 50% added to the reaction bottle; weighed 100g monobutyltin trichloride liquid into the Constant pressure funnel slowly into the reaction bottle, and then constant temperature reaction 2h. During the incubation process, 20% of the diluted additive was added every 30 minutes. After the completion of the reaction, the monobutyl tin oxide obtained by the reaction was filtered through a cloth funnel, and the filter cake was transferred to a 500-M beaker and heated to about 200 ml of water. The washing temperature was controlled at 60 to 65C, The resulting filter cake was dried with a rotary evaporator at a drying temperature of 85 to 95 ° C to finally obtain 73.78 g of monobutyltin oxide in a yield of 99.4%.
