 Title    Darstellung und thermische Zersetzung von Erdalkalimetall-Carbamoylphospliaten Preparation and Thermal Decomposition of Carbamoylphosphates of Alkaline-earth Metals  
 Abstract    After the formation of carbamoylphosphate through the reaction of KH2PO4 with KNCO in aqueous solution, unreacted phosphate and carbamoylphosphate can be separated by fractional precipitation with barium (first step) and calcium or strontium or barium salt solutions (second step) at low temperatures. The carbamoylphosphates of the alkaline earth metals are decomposed above 100 °C to yield predominantly diphosphates and urea. In aqueous suspensions the decomposition proceeds even at room temperature. -The chemical shifts of the phosphorus atom of the carbamoylphosphate ion between pH 6.5 and 8.2 are given.
