NMR spectroscopic and polarographic studies of the reaction of decomposition of cumene hydroperoxide by dithiophosphoric acids

1.	Dithiophosphoric acids are either not catalysts or only act as moderate catalysts as a function of the structure in reactions of decomposition of CHP.
2.	The real catalyst of decomposition of CHP in the presence of dithiophosphoric acids is the sulfuric acid formed during the oxidation of the dithiophosphoric acids, or the combination of the sulfuric acid with phosphours-containing acids.
3.	Slow and fast stages of kinetic decomposition of CHP were detected, and the kinetic parameters of the fast stage were determined.
