  2. Peroxide - Wikipedia

    en.wikipedia.org/wiki/Peroxide

    In addition to hydrogen peroxide, some other major classes of peroxides are: Peroxy acids, the peroxy derivatives of many familiar acids, examples being peroxymonosulfuric acid and peracetic acid, and their salts, one example of which is potassium peroxydisulfate. Main group peroxides, compounds with the linkage E−O−O−E (E = main group ...

  3. Hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_peroxide

    Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.

  4. Sodium peroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_peroxide

    Sodium peroxide is an inorganic compound with the formula Na 2 O 2.This yellowish solid is the product of sodium ignited in excess oxygen. [3] It is a strong base. This metal peroxide exists in several hydrates and peroxyhydrates including Na 2 O 2 ·2H 2 O 2 ·4H 2 O, Na 2 O 2 ·2H 2 O, Na 2 O 2 ·2H 2 O 2, and Na 2 O 2 ·8H 2 O. [4] The octahydrate, which is simple to prepare, is white, in ...

    Methyl ethyl ketone peroxide, benzoyl peroxide and to a smaller degree acetone peroxide are used as initiators for radical polymerization of some thermosets, e.g. unsaturated polyester and vinyl ester resins, often encountered when making fiberglass or carbon fiber composites (CFRP), with examples including boats, RV units, bath tubs, pools ...

  6. Calcium peroxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_peroxide

    Calcium peroxide or calcium dioxide is the inorganic compound with the formula CaO 2. It is the peroxide (O 2 2− ) salt of Ca 2+ . Commercial samples can be yellowish, but the pure compound is white.

  7. Benzoyl peroxide - Wikipedia

    en.wikipedia.org/wiki/Benzoyl_peroxide

    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− ).

  8. Potassium peroxide - Wikipedia

    en.wikipedia.org/wiki/Potassium_peroxide

    Potassium peroxide is an inorganic compound with the molecular formula K 2 O 2. It is formed as potassium reacts with oxygen in the air, along with potassium oxide (K 2 O) and potassium superoxide (KO 2). Crystal structure. Potassium peroxide reacts with water to form potassium hydroxide and oxygen: 2 K 2 O 2 + 2 H 2 O → 4 KOH + O 2 ↑

  9. Peroxide value - Wikipedia

    en.wikipedia.org/wiki/Peroxide_value

    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 of O2 =0.5 mmol of O2, where 2 is valence).
