【Abstract】 The Liquid Liquid equilibrium data of octane water and octane phosphoric acid water system were measured. The phase equilibrium data have been correlated by NRTL equation with five parameters and the accuracy of the calculation is high enough for the design processes. the LLE data about octane water and octane phosphoric acid water system can be used to the azeotropic distillation calculation for concentration of phosphoric acis.更多还原
