Manufacturing Process

CG 516, mixed mono- and di- 2-ethylhexyl phosphates, is typically manufactured by reacting 2-ethyl hexanol with P2O5. The reaction is exothermic and cooling is required to maintain the temperature. In most processes, excess 2-ethyl hexanol is used to drive the reaction to completion, and the unreacted 2-ethyl hexanol is removed by distillation.

Chemical Reactions

Like other phosphates, CG 516 may be hydrolyzed in the presence of water and an acid or basic catalyst. 2-Ethyl hexanol and phosphoric acid are the products in the hydrolysis.
