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; and E) filtering the granules; F) optionally neutralizing the filtered granules with an aqueous solution of alkali metal hydroxides; and G) drying the granules under reduced pressure. The product obtained contains at least 90:10 ratio of mono:dialkyl phosphate ester, free phosphoric acid
