Zusammenfassung:Provided herein is a process for producing alkyl phosphate and a salt thereof of Formula I,wherein, R= C16-22 and M = H, K or Na the said process comprising steps of:A) reacting fatty alcohol of Formula II with polyphosphoric acid (PPA) of 115- 120% of Formula III;B) converting the product of step A) into granules;C) ageing the granules of alkyl phosphate esters for maximum 10 days;D) wetting the granules with water after ageing; andE) filtering the granules;F) optionally neutralizing the filtered granules with an aqueous solution of alkali metal hydroxides; andG) drying the granules under reduced pressure.The product obtained contains at least 90:10 ratio of mono: dialkyl phosphate ester, free phosphoric acid
