On the thermal decomposition of tert.-butyl hydroperoxide, its sensitivity to metals and its kinetics, studied by thermoanalytic methods

Accounting for molecular flexibility in photoionization: case of tert-butyl hydroperoxide

“…These species likely originate from the decomposition of tBuOOH and subsequent reactions upstream of the ionization zone (mixing tank, sampling lines) in agreement with the literature [39][40][41][42]. tBuOOH is among the most stable hydroperoxides but relatively unstable and sensitive to temperature and pressure conditions, contaminations or frictions 10. The signal at m/z 58 also originates from an impurity of the sample, in this case acetone (see left panel of Fig.S1, ESI †), another characteristic product of tBuOOH decomposition 43.…”

“…The synthesis and purification of hydroperoxides is difficult because of their tendency to spontaneously decompose exothermically. 8 tert -Butyl hydroperoxide ( t BuOOH), a tertiary hydroperoxide, is one of the most stable hydroperoxides, 9 with many interesting industrial applications (see Willms et al 10 and references therein). t BuOOH is also a widely used radical precursor for OH kinetic measurements with organic species.…”

On-Demand Photochemical Synthesis of Hydrogen Peroxide from Alkylated Anthraquinones

“…It is reasonable to assume that reactor design optimization and the use of pure oxygen can further hasten the production of H 2 O 2 . The on-demand synthesis of H 2 O 2 could also be used to produce other hydrogen peroxide-derived products that are thermally unstable at room temperature, like tert -butyl hydroperoxide, di- tert -butylperoxide, and peracetic acid, among others. , We believe that this photochemical reaction is a first step to quickly and efficiently produce H 2 O 2 on demand.…”

Direct Tertiary Butyl Alcohol Formation via Catalytic Liquid Phase Isobutane Oxidation with Molecular Oxygen

“…The industrial liquid phase oxidation of isobutane with dioxygen is carried out below isobutane’s critical temperature ( T c = 135 °C), generating a mixture of TBA and TBHP. − The TBHP is typically used as an oxidant for propylene epoxidation. To shift the selectivity toward TBA formation, there is interest in developing catalytic systems that can selectively decompose TBHP to TBA. ,− A variety of transition-metal based catalysts, such as Mn, , Ru, Fe, Cu, Eu, Co, and V, as well as halogenated metalloporphyrin complexes ,− have been reported for catalytic oxidation of various alkanes using dioxygen to produce oxygenated chemical precursors such as alcohols and acids. A similar one-pot approach has been reported to form KA (ketone+alcohol) from cyclohexane oxidation followed by catalytic hydroperoxide decomposition using either homogeneous − or heterogeneous , catalysts.…”
