Abstract

1466953 Calcium phosphates LENINGRAD TEKHNOLOGICH INST IM LENSOVETA and VINNIT KHIMICHE KOMBINAT IM JA M SVERDLOVA 27 Feb 1974 8807/74 Heading C1A Mono- and di-calcium phosphates are produced by effecting from 10-40% neutralization of the first H<SP>+</SP> ion of phosphoric acid (40-55% P 2 O 5 ) containing not more than 0À3% F- with rock phosphate at 90-130‹ C., reacting the pulp formed with calcium carbonate, oxide and/or hydroxide at 50-100‹ C. until the pH of a 0À24% (w./v., g./100 ml.) aqueous solution is from 3-6 and drying the product at 80- 150‹ C.
