2synthesis methods
-

Yield: 99.3%

Reaction Conditions:

in chlorobenzene at 25;Temperature;Solvent;

Steps:

2; 3-5 Example 2
At a temperature of 25°C, a 100 watt ultrasonic oscillator oscillates, and a stirring rate of 100 rpm is controlled,Into a three-necked flask containing 100ml of 18.2g of sodium tetraphenylborate (5% excess) dissolved in a three-necked flask was added dropwise 50ml of a solution of 16g of tetra-n-butylammonium bromide in chlorobenzene,The dripping is completed within 10-15 minutes, and then the reaction is continued for 1 hour to stop the reaction.The precipitate formed by the reaction was collected by filtration to obtain 27.8 g of tetra-n-butylammonium tetraphenylborate as a white product with a yield of 99.3%.Ion chromatography tested its sodium ion content of 7.5ppm, and the purity of tetra-n-butylammonium tetraphenylborate was 99.8%.
