Abstract

1505025 Aluminium phosphate HOECHST AG 27 April 1976 [27 Jan 1975 24 July 1975] 17077/76 and 17078/76 Heading C1A AlH 3 (PO 4 ) 2 À3H 2 O is prepared by allowing it to crystallize from a solution which contains aluminium phosphate, water and a water-miscible organic liquid, the Al 2 O 3 :P 2 O 5 molar ratio in the solution being 1:2 to 1:6. The organic liquid may be wholly or partially miscible with water and may form a second phase in the presence of the dissolved phosphate.
