Abstract: AQUEOUS SOLUTIONS OF AMMONIUM FLUORIDE CAN BE TRANSFORMED INTO A SUBSTANTIALLY ANHYDROUS MIXTURE CONTAINING AT LEAST 90% AMMONIUM BIFLUORIDE AND CORRESPONDINGLY 10% OR LESS OF AMMONIUM FLUORIDE BY DISTILLING OFF A PORTION OF THE AQUEOUS COMPONENT OF THE SOLUTION AT A POT TEMPERATURE RANGING UP TO ABOUT 150*C. UNTIL SAID SOLUTION CONTAINS FROM 5 TO 30% WATER BASED ON THE ORGINIAL WEIGHT OF AMMONIUM FLUORIDE, AND THEN CONTINUING HEATING THE SOLUTION UNTIL AT LEAST ABOUT 90% OF THE NONAQUEOUS SOLUTION COMPONENT IS AMMONIUM BIFLUORIDE, WITH SUFFICIENT WATER BEING ADDED TO REPLACE THAT LOST DURING SAID CONTINUED HEATING SO AS TO MAINTAIN THE WATER CONTENT OF THE SOLUTION AT FROM ABOUT 5% TO ABOUT 30% AND THEN REDERING THE MIXTURE SUBSTANTIALLY ANHYDROUS BY REMOVING THE RESIDUAL WATER AT A TEMPERATURE RANGING FROM ABOUT 50*C. UP TO 130*C. AT A PRESSURE OF LESS THAN ABOUT 700 MM. OF MERCURY.
