Diammonium phosphate, also known as diammonium hydrogen phosphate, diammonium phosphate, is a colorless transparent monoclinic crystal or white powder. The relative density is 1.619. Easily soluble in water, insoluble in alcohol, acetone, and ammonia. Decompose when heated to 155°C. When exposed to the air, it gradually loses ammonia and becomes ammonium dihydrogen phosphate. The aqueous solution is alkaline, and the pH value of 1% solution is 8. Reacts with ammonia to generate triammonium phosphate.
The production process of diammonium phosphate: It is made by the action of ammonia and phosphoric acid.
Uses of diammonium phosphate: used as a fire retardant for fertilizers, wood, paper, and fabrics, and also used in medicine, sugar, feed additives, yeast and other aspects.
It gradually loses ammonia in the air and becomes ammonium dihydrogen phosphate. The water-soluble quick-acting fertilizer is used in various soils and various crops. It can be used as seed fertilizer, base fertilizer and top dressing. Do not mix it with alkaline fertilizers such as plant ash, lime nitrogen, lime, etc., so as not to reduce fertilizer efficiency.
