S-Sätze Betriebsanweisung:
S22:Staub nicht einatmen.
S24/25:Berührung mit den Augen und der Haut vermeiden.
Chemische Eigenschaften
white not hygroscopic crystal(s); prepared by reacting boric acid and phosphoric acid up to 1200°C: B(OH)3+H3PO4=BPO4+3H2O; used in special glasses [HAW93]
Physikalische Eigenschaften
Physical Properties White infusible solid; density 1.873 g/mL; sublimates slowly above 1,450°C; soluble in water, decomposes to phosphoric acid and boric acid; pH of 1% solution is ~2.0.
Verwenden
Boron phosphate is used as an acid catalyst for dehydration of alcohols to olefins; isomemization of olefins; nitration of aromatic hydrocarbons; polymerization of aldehydes and other synthetic reactions. It also is used as a flux in silica-based porcelain and ceramics; special glasses; and acid cleaners.
Verwenden
Boron phosphate is used as a catalyst for dehydration as well as in other organic reactions. It is employed as a source of phosphates involved in the exchange reaction to prepare metal phosphates. It finds application in refractories, ceramics and flame-retardants.
synthetische
Boron phosphate is prepared by heating an equimolar mixture of boric acid and phosphoric acid at 1,000 to 1,200°C:
H₃BO₃ + H₃PO₄ → BPO₄ + 3H₂O
Various preparative methods are adopted at nonstoichiometric formulations, incomplete dehydration or using oxide additives to obtain boron phosphate of varying purity for its catalytic applications. The compound also forms hydrates (tri- tetra-, penta-, and hexahydrates) which readily decompose in water to phosphoric acid and boric acid.
Flammability and Explosibility
Non flammable
