Chemische Eigenschaften
Calcium peroxide is a grayish-white or
yellowish odorless crystalline solid.
Physikalische Eigenschaften
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.
Verwenden
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.
Allgemeine Beschreibung
A grayish white granular material. Used in baking, in medicine, in bleaching oils.
Air & Water Reaktionen
Isoluble in water and slowly decomposed by water to produce calcium hydroxide (slaked lime) [Sax, 9th ed., 1996, p. 636].
Reaktivit?t anzeigen
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.
Brandgefahr
Behavior in Fire: Can increase severity of fire. Containers may explode.
Sicherheitsprofil
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.
m?gliche Exposition
Calcium peroxide is used as a seed
disinfectant, an antiseptic, and a rubber stabilizer.
