  2. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    A typical mixture is 3 parts of concentrated sulfuric acid and 1 part of 30 wt. % hydrogen peroxide solution; [1] other protocols may use a 4:1 or even 7:1 mixture. A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution ( NH 4 OH , or NH 3 (aq) ), and 30% hydrogen peroxide.

  3. Pinnick oxidation - Wikipedia

    en.wikipedia.org/wiki/Pinnick_Oxidation

    Hydrogen peroxide (H 2 O 2) can be used as HOCl scavenger whose byproducts do not interfere in the Pinnick oxidation reaction: HOCl + H 2 O 2 → HCl + O 2 + H 2 O. In a weakly acidic condition, fairly concentrated (35%) H 2 O 2 solution undergoes a rapid oxidative reaction with no competitive reduction reaction of HClO 2 to form HOCl. HClO 2 ...

  4. Schenck ene reaction - Wikipedia

    en.wikipedia.org/wiki/Schenck_ene_reaction

    The Schenck ene reaction or the Schenk reaction is the reaction of singlet oxygen with alkenes to yield hydroperoxides. The hydroperoxides can be reduced to allylic alcohols or eliminate to form unsaturated carbonyl compounds. It is a type II photooxygenation reaction, and is discovered in 1944 by Günther Otto Schenck. [1]

  5. Milas hydroxylation - Wikipedia

    en.wikipedia.org/wiki/Milas_hydroxylation

    The Milas hydroxylation is an organic reaction converting an alkene to a vicinal diol, and was developed by Nicholas A. Milas in the 1930s. [1] [2] The cis-diol is formed by reaction of alkenes with hydrogen peroxide and either ultraviolet light or a catalytic osmium tetroxide, [3] vanadium pentoxide, or chromium trioxide.

  6. Fenton's reagent - Wikipedia

    en.wikipedia.org/wiki/Fenton's_reagent

    An example hydroxylation reaction involves the oxidation of barbituric acid to alloxane. [9] Another application of the reagent in organic synthesis is in coupling reactions of alkanes. As an example tert-butanol is dimerized with Fenton's reagent and sulfuric acid to 2,5-dimethyl-2,5-hexanediol. [10]

  7. Peracetic acid - Wikipedia

    en.wikipedia.org/wiki/Peracetic_acid

    In the presence of a strong acid catalyst, such as sulfuric acid, acetic acid and hydrogen peroxide produce peracetic acid: [3] H 2 O 2 + CH 3 CO 2 H ⇌ CH 3 CO 3 H + H 2 O. However, in concentrations (3-6%) of vinegar and hydrogen peroxide marketed for household use, mixing without a strong acid catalyst will not form peracetic acid.

  8. 3,3',5,5'-Tetramethylbenzidine - Wikipedia

    en.wikipedia.org/wiki/3,3',5,5'-Tetramethylbenzidine

    The resulting one-electron oxidation product is a diimine-diamine complex, which causes the solution to take on a blue colour, [2] and this colour change can be read on a spectrophotometer at the wavelengths of 370 and 650 nm. The reaction can be halted by addition of acid or another stop reagent.

  9. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    This combustion process produces gaseous sulfur dioxide (SO 2) and sulfur trioxide (SO 3) which are then used to manufacture "new" sulfuric acid. Hydrogen peroxide (H 2 O 2) can be added to sulfuric acid to produce piranha solution, a powerful but very toxic cleaning solution with which substrate surfaces can be cleaned. Piranha solution is ...
