General Description
A grayish white granular material. Used in baking, in medicine, in bleaching oils.
Reactivity Profile
CALCIUM PEROXIDE(1305-79-9) 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].
Air & Water Reactions
Isoluble in water and slowly decomposed by 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.
Potential Exposure
Calcium peroxide is used as a seed
disinfectant, an antiseptic, and a rubber stabilizer.
Fire Hazard
Behavior in Fire: Can increase severity of fire. Containers may explode.
First aid
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
30 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately. If
this chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart
action has stopped. Transfer promptly to a medical facility.
When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do
not make an unconscious person vomit. Medical observation
is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid
for pulmonary edema, a doctor or authorized paramedic may
consider administering a drug or other inhalation therapy
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
Description
Calcium peroxide is a grayish-white or yellowish odorless crystalline solid. Molecular weight=72.1;Freezing/Melting point=275℃ (decomposes). HazardIdentification (based on NFPA-704 M Rating System):Health 1, Flammability 0, Reactivity 1. Insoluble in water.
Chemical Properties
Calcium peroxide is a grayish-white or
yellowish odorless crystalline solid.
Chemical Properties
White or yellowish powder; odorless;
almost tasteless. Decomposes at approximately
200C. Almost insoluble in water; soluble in acids
with formation of hydrogen peroxide. Available
oxygen 22.2% (min 13.3% in technical grade).
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.
Definition
ChEBI: Calcium peroxide is a member of calcium oxides.
storage
Color Code—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flammables and combustibles. Prior to working with calciumperoxide you should be trained on its proper handling andstorage. Calcium peroxide must be stored to avoid contactwith combustible materials (such as wood, paper, oil, fuels,etc.) since violent reactions occur. Store in tightly closedcontainers. See OSHA Standard 1910.104 and NFPA 43ACode for the Storage of Liquid and Solid Oxidizers fordetailed handling and storage regulations.
