The AR grade phosphates were recrystallized once from water. The composition of the eutonics was determined by an isopiestic method. The sodium salt was then estimated by difference. The ammonium salt was determined gravimetrically as ammoniumtetraphenyl borate 1 and the total salt content was determined by evaporation to constant weight in vacuum over H 2SO 4. Table 1 b The solid phases are: A=Na 2HPO 4♱2H 2O B=NaNH 4HPO 4♴H 2O C=(NH 4) 2HPO 2.Ĭonventional measurements were made on aliquots of saturated solutions. Table 1 a The molalities were calculated by the compiler. (Please see footnotes following the table(s).) Solubility in the Na 2HPO 4-(NH 4) 2HPO 2-H 2O system at 25 ° Chemical 1 AZprocede is a real-time simulation software of various chemical processes and equipment such as distillation column, extraction columns and separation funnel, chemical reactors, evaporator and crystallizer, pump, centrifugal compressor, and heat exchangers.
