Phosphoric Acids and Phosphates

摘要: Most commercial applications of phosphorus-containing materials are based on phosphoric acids and the phosphates. Uses, other than as fertilizer, include in detergency, foods food processing, dental materials, dentifrices, metal surface treatments, flame retardency, etc. Structures properties orthophosphoric acid condensed presented. The manufacture technical- food-grade by thermal wet purification processes, well some uses various acids, discussed. The chemistry orthophosphates phosphates Emphasis is placed alkali calcium salts their solution properties. Properties specific to phosphate such hydrolysis ion complexation outlined. Manufacturing schemes for described attention given control product properties. Keywords: phosphoric acids; ortho acid; condensed; orthophosphates; pyrophosphates; phosphates; polyphosphates; phosphate salts; detergents; fertilizers
