tert-Butyl hydroperoxide (tBuOOH) is the organic compound with the formula (CH3)3COOH. It is one of the most widely used hydroperoxides in a variety of oxidation processes, for example the Halcon process. It is normally supplied as a 69–70% aqueous solution. Compared to hydrogen peroxide and organic peracids, tert-butyl hydroperoxide is less reactive and more soluble in organic … WebDec 15, 2024 · In particular, aliphatic compounds are produced by O 3-t-BuOH through a Criegee-type mechanism leading to a cleavage of C=C bonds (Ramseier and von Gunten, 2009), which mitigates both EDC and UV 254 and can explain the lower ΔEDC/ΔUV 254 ratios compared to ClO 2 (Fig. 1 c, Table S1). 3.2.3. mccoy power report 2020
