Abstract
A process for the preparation of crystal double potassium-ammonium orthophosphate by the interaction of solution of monosubstituted potassium phosphate with aqueous solution of ammonia compounds. Average double potassium-ammonium orthophosphate of particular composition with its high yield is obtained with addition to 22-33.5 % solution of KHPOconcentrated 22-23 % aqueous solution of ammonia, taken in 2-4 –multiple surplus to stoichiometrically required quantity of NH, ageing of mixture at temperature of 0-5 °C for 24 hours with following separation of solid phase and its ageing on air at 15÷25 °C to achievement of constant weight.
