Physicochemical Property of 1-Hydroxyethylidene-1,1-diphosphonic acid powder
1-Hydroxyethylidene-1,1-diphosphonic acid CAS 2809-21-4 is white crystal. Industrial product is colourless to light yellow transparent liquid. Soluble in water, soluble in methanol and ethanol.
Production methodprocess of 1-Hydroxyethylidene-1,1-diphosphonic acid powder
- 1-Hydroxyethylidene-1,1-diphosphonic acid Raw Materials can be produced by mixing phosphorus trichloride with glacial acetic acid, heating and distillation to obtain acetyl chloride (see 00510), and then reacting with phosphinic acid.
- By nucleophilic addition of diethylenetriamine to formaldehyde, the addition product is esterified with the hydrolysis product of phosphorus trichloride and neutralised to give 1-Hydroxyethylidene-1,1-diphosphonic acid powder.
