This report proffers a thorough cost evaluation of the production of HEDP or Etidronic acid from aqueous acetic acid and phosphorous trichloride. The process involves stirring aqueous acetic acid in a reaction kettle followed by the dropwise addition of phosphorous trichloride to separate hydrogen chloride from the generated acetyl chloride. The reaction is further carried out for 1.5-3 hours, followed by adding water in the reaction kettle, hydrolysing and recovering acetic acid, and finally sweeping the products using steam and cooling to obtain hydroxyl ethylidene diphosphonic acid or HEDP.
