When H2O2 acts as a reducing agent, oxygen gas is also produced. For example, hydrogen peroxide will reduce sodium hypochlorite and potassium permanganate, which is a convenient method for preparing oxygen in the laboratory: NaOCl + H2O2 → O2 + NaCl + H2O. 2 KMnO4 + 3 H2O2 → 2 MnO2 + 2 KOH + 2 H2O + 3 O2.
Peroxide. In chemistry, peroxides are a group of compounds with the structure R−O−O−R, where the R's represent any element and O's are single oxygen molecules. [1] [2] Oxygens are joined to each other and to adjacent elements through single covalent bonds, denoted by dashes or lines. The O−O group in a peroxide is often called the ...
From hydrogen peroxide. Dialkyl peroxides, e.g., dicumyl peroxide, are synthesized by addition of hydrogen peroxide to alkenes or by O-alkylation of hydroperoxides. Diacyl peroxides are typically prepared by treating hydrogen peroxide with acid chlorides or acid anhydrides in the presence of base: H 2 O 2 + 2 RCOCl → (RCO 2) 2 + 2 HCl
Benzoyl peroxide is a chemical compound (specifically, an organic peroxide) with structural formula (C 6 H 5 −C(=O)O−) 2, often abbreviated as (BzO) 2. In terms of its structure, the molecule can be described as two benzoyl ( C 6 H 5 −C(=O)− , Bz) groups connected by a peroxide ( −O−O− ).
HAZMAT 5.1 placard on a pail of UN 2468,Trichloroisocyanuric acid for use in swimming pools. An oxidizer is a material that may, generally by yielding oxygen, cause or enhance the combustion of other materials.
Calcium peroxide. Chlorine peroxide. Chromium (VI) oxide peroxide. Copper peroxide.
Peroxidases or peroxide reductases (EC number 1.11.1.x) are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides .
The peroxide value is defined as the amount of peroxide oxygen per 1 kilogram of fat or oil. Traditionally this was expressed in units of milliequivalents , although in SI units the appropriate option would be in millimoles per kilogram (N.B. 1 milliequivalents = 0.5 millimole; because 1 mEq of O2 =1 mmol/2=0.5 mmol of O2, where 2 is valence).
Methyl ethyl ketone peroxide. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Methyl ethyl ketone peroxide ( MEKP) is an organic peroxide with the formula [ (CH 3 ) (C 2 H 5 )C (O 2 H)] 2 O 2. MEKP is a colorless oily liquid.
Main group peroxides are peroxide derivatives of the main group elements. Many compounds of the main group elements form peroxides, and a few are of commercial significance. Examples. With thousands of tons/year being produced annually, the peroxydisulfates, S 2 O 2− 8, are preeminent members of this class.
