Description

Ammonium dihydrogen phosphate is a colorless transparent tetragonal crystal. soluble in water, slightly soluble in alcohol, insoluble in acetone.
Ammonium dihydrogen phosphate or monoammonium phosphate is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acid. It crystallizes in quadratic prisms. Monoammonium phosphate is often used in the blending of dry agricultural fertilizers. It supplies soil with the elements nitrogen and phosphorus in a

Ammonium dihydrogen phosphate Use and Manufacturing

Uses

It is mainly used to prepare compound fertilizers, and can also be directly applied to farmland; as analytical reagents and buffers; in the food industry as leavening agents, dough regulators, yeast foods, brewing fermentation aids, and buffers. Also used as an animal feed additive. It is a high-efficiency nitrogen and phosphorus compound fertilizer. It can be used as a fire retardant for wood, paper and fabric, a dispersant for fiber processing and dye industry, a glaze for enamel, a compounding agent for fire-resistant coatings, an ember extinguisher for matchsticks and candle wicks, and a dry powder fire extinguishing agent. It is also used in printing plate making and pharmaceutical manufacturing. Used as fertilizer, fire retardant, and also used in printing and plate making, medicine and other industries. Prepare buffer and culture medium, and produce flame retardant and dry powder fire extinguishing agent for phosphate, fluorescent powder, wood, paper and fabric. The analytical standard is used for nitrogen determination by Kjeldahl method. After the first opening and use, it is recommended to store with argon or nitrogen.
