Preparation of boron phosphate

Preparation of boron phosphate

12 g of boric acid are heated on the steam bath with 20 ml of sirupy phosphoric acid (85%) in an evaporating dish. The mixture gradually thickens to a stiff paste and a spatula should be used to keep it from adhering to the sides of the vessel. When the reaction mass has become sufficiently hard and dry, it is ground to a coarse powder in a mortar and re-transferred to the basin. The latter is heated for about two hours on a sand bath with the full flame of a Tirrell burner. The material shrinks considerably in volume due to loss of water and becomes a fine dry powder. The material is finally dehydrated by heating in a large crucible for one hour over a Meker burner. On cooling, the mass is readily separated from the crucible and reground. It is then boiled for 15 to 30 minutes with a mixture of 200 ml of water and 5 ml of concentrated hydrochloric acid to remove any excess of partially reacted starting material. After filtration by suction the white product is dried at 100° C. The yield of boron phosphate 87%. Boron phosphate is vigorously decomposed by hot con centrated alkali to give sodium borate and phosphate.
