Abstract

The invention concerns an improved precipitation process in the manufacture of coating powders based on polyamides having at least ten aliphatically bound carbon atoms per carbonamide group. Rapid cooling takes place with stirring mainly by distilling the ethanol solvent until the temperature of precipitation is set in the range from 90 DEG to 113 DEG C. With the beginning of the saturation limit (about 125 DEG C.), the temperature difference between the coolant in the jacket and the solution inside is maintained at most at +/-3 DEG C. The solution is maintained during the precipitation stage at constant temperature (isothermal procedure) by further distillation of the ethanol.
