Abstract

1322724 Halogen-containing complex Al phosphate IMPERIAL CHEMICAL INDUSTRIES Ltd 29 May 1970 [12 June 1969] 1737/73 Divided out of 1322722 Heading C1A A solid, water-soluble halogen-containing complex phosphate of aluminium wherein the ratio of the number of gram atoms of aluminium to the number of gram atoms of phosphorus is substantially 1 : 1 and which contains at least one chemically-bound molecule of water may be prepared (a) by reacting an aluminium compound with water and phosphoric acid or a compound capable of forming phosphoric acid under the reaction conditions and, when an aluminium compound other than a halide is used, a halogen acid, and separating the solid product or (b) by hydrolysing a complex phosphate as claimed in Application No. 29862/69 (Serial No. 1,322,722) in which the ratio of the number of gram atoms of aluminium to the number of gram atoms of phosphorus is substantially 1 : 1. The complex phosphates of the invention may contain 1 to 5 molecules of water, and the ratio of the number of gram atoms of aluminium to the number of gram atoms of halogen is preferably substantially 1 : 1. The complex phosphates of the invention decompose on heating to give crystalline or amorphous aluminium phosphate. Fine particles of aluminium phosphate may be prepared by rapid heating of a complex phosphate of the invention to a temperature greater than 900‹ C. and grinding the resultant mass.
