Calcium peroxide Chemical Properties,Uses,Production
Chemical Properties
Calcium peroxide is a grayish-white or yellowish odorless crystalline solid.
Physical properties
For all practical purposes, calcium peroxide is insoluble in water but will dissolve in acid to form H2O2. When in contact with water, it will immediately begin to decompose releasing oxygen.
Uses
Calcium Peroxide is a dough conditioner which exists as a white or yellowish powder or granule that is insoluble in water. it improves dough strength, grain, and texture, and increases absorption and crumb resiliency. it is used in bakery products.
General Description
A grayish white granular material. Used in baking, in medicine, in bleaching oils.
Air & Water Reactions
Isoluble in water and slowly decomposed by water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].
Reactivity Profile
Calcium peroxide is an explosion hazard if mixed with finely divided organic matter. Noncombustible but accelerates the burning of combustible material: mixtures of combustible material and the peroxide can be ignited by friction or contact with moisture. Mixtures with polysulfide polymers may ignite. Decomposes rapidly above 200° C. Strongly basic Reacts with water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].
Hazard
Strong oxidizing agent. Dangerous fire risk in contact with organic materials. Irritating in con- centrated form.
Health Hazard
Inhalation of dust irritates nose and throat. Dust also irritates eyes and skin on contact and irritates mouth and stomach if ingested.
Fire Hazard
Behavior in Fire: Can increase severity of fire. Containers may explode.
Safety Profile
Irritating in concentrated form. Will react with moisture to form slaked lime. Flammable if hot andmixed with finely dwided combustible material. Mixtures with oxiduable materials can also be ignited by grinding and are explosion hazards. A strong alkali. An oxidizer. Mixtures with polysulfide polymers may ignite. See also CALCIUM COMPOUNDS, CALCIUM HYDROXIDE, and PEROXIDES, INORGANIC.
Potential Exposure
Calcium peroxide is used as a seed disinfectant, an antiseptic, and a rubber stabilizer.
Shipping
UN1457 Calcium peroxide, Hazard Class: 5.1; Labels: 5.1-Oxidizer
Incompatibilities
Slow reaction with water or other forms of moisture, releasing calcium hydroxide Calcium peroxide is a strong alkali and a strong oxidizer. Incompatible with reducing agents, including hydrides; acids, combustible materials; polysulfide polymers. Rapid decomposition 》200C
