Embodiment example 1
[0026] Take 2,6-dichlorobenzonitrile:(n+m):potassium carbonate:N-methylpyrrolidone:toluene=1:1:(1.1~1.5):(6~8):(1.2~1.5) Molar ratio preparation, where n is the amount of sodium sulfide, m is the amount of bisphenol A, and the ratio of n to m is 1:9. Various raw materials were placed in a reactor with a water separator, a condenser, a stirrer and a heater, and the reaction was stirred at 140 to 170 ° C and normal pressure for 2 to 4 hours. When the high system temperature reaches 200°C, when the rod climbing phenomenon occurs, N-methylpyrrolidone is injected into the reaction kettle to dilute the reaction product, so that the reaction product can be quickly put into the precipitation kettle for precipitation. The obtained precipitate is dried and pulverized into particles with a particle size of 0.5-1.5 cm in a pulverizer, and then the particles are ground into fine powders in a size of 0.005-0.1 mm by a colloid mill. After the fine powder is soaked in methanol or ethanol org...
