DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) 19F and 31P NMR spectroscopy were used to study the kinetics of the hydrolysis of LiPF6 in the homogeneous solvent system propylene carbonate (PC)-di-Me carbonate (DMC)-H2O. It was found that the main products of the hydrolysis are HF, LiPO2F2 and Li2PO3F. The content of POF3 and PF5 was negligibly low. We set up a hypothesis that the main factor detg. the rate of the process is the so-called secondary' catalytic effect, caused by solvated H+ ions. .
