Phosphate esters are compounds formed by replacing hydrogen of an acid by a hydrocarbon radical of the ethyl type. They are considered as derivatives of the triprotic acid and phosphoric acid O=P (OH) 3, with the general formula RxH3-xPO4, where x=1 for mono, x=2 for di, and x=3 for tri esters. Phosphate esters are also called as organophosphates and belong to a class of anionic surface-active agents. The most commonly used phosphate esters are triaryl/alkyl aryl phosphate esters, trialkyl phosphate esters, and bisphosphates. Phosphate esters are the most widely used ester-based fluids in lubricants and hydraulic applications. Owing to the high-performance and safety they offer, phosphate esters are used in applications such as solvents, plasticizers, paints & coatings, and fire retardants. 1.
