Preparation of di-t-alkyl peroxides and t-alkyl hydroperoxides from n-alkyl ethers

A process for production of a t-alkyl peroxide compound includes the steps of: a) reacting an n-alkyl t-alkyl ether with a reactant mixture comprising an acid catalyst and a compound of the formula RO2H??(I) ?where R is H or t-alkyl, provided that if R is t-alkyl the t-alkyl peroxide compound product is a di-t-alkyl peroxide, and b) isolating a reaction product comprising said t-alkyl peroxide compound from the mixture resulting from step a). The process can be used to prepare t-butyl hydroperoxide or di-t-butyl peroxide from methyl t-butyl ether. Sulfuric acid may be used as the acid catalyst.

The decomposition rates and products of various t-alkyl t-butyl peroxides were examined in cumene at several temperatures.The decomposition of these peroxides took place homolytically, depending on the structure of the t-alkoxyl moieties (RC(CH3)2-O), and was retarded in the order: R = (CH3)3CCH2 > (CH3)2CH > CH3CH2CH2 > PhCH2 > CH3CH2 > ClCH2 > CH3.The rate constants for the electron-donating alkyl substituents at 150 deg C are correlated very well to a Taft equation (log kd = -10.93Σ?*-6.61 (correlation coefficient of 0.9501)), which is fairly different from the equation log kd = -0.131Σ?*-3.422 for electron-withdrawing polar substituents.From this correlation and a product analysis, the nature of the polar character at the transition state of the decomposition is discussed.
