Polaris Use and Manufacturing

Methods of Manufacturing

Phosphorus trichloride method is prepared by reacting glycine with formaldehyde and phosphorus trichloride at 110℃. Phosphorous acid method is made by one-step condensation of glycine, formaldehyde and phosphorous acid in acid medium. It can also be synthesized by using phosphorous acid as a by-product in the production of diarrhea. The chloromethylphosphonic acid method is prepared by glycine and chloromethylphosphonic acid methylphosphonation.

Uses

Chemical ripener; plant growth regulator.
