Sodium percarbonate or sodium carbonate peroxide is a chemical substance with empirical formula Na 2 H 3 CO 6. It is an adduct of sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate) whose formula is more properly written as 2 Na 2 CO 3 · 3 H 2 O 2. It is a colorless, crystalline, hygroscopic and water ...
Active oxygen bleaching agents include sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulfate, and urea peroxide. These compounds release hydrogen peroxide during the wash cycle, but the release of hydrogen peroxide is low when these compounds are used in temperatures below 45 °C (113 °F).
Caustic ingestion occurs when someone accidentally or deliberately ingests a caustic or corrosive substance. Depending on the nature of the substance, the duration of exposure and other factors it can lead to varying degrees of damage to the oral mucosa , the esophagus , and the lining of the stomach .
Sodium percarbonate (Na 2 H 3 CO 6), an adduct of hydrogen peroxide and sodium carbonate ("soda ash" or "washing soda", Na 2 CO 3). Dissolved in water, it yields a solution of the two products, that combines the degreasing action of the carbonate with the bleaching action of the peroxide. Sodium perborate (Na 2 H 4 B 2 O 8).
Bleach activation is also known as perhydrolysis. Persalts are inorganic salts that are used as hydrogen peroxide carriers (examples include sodium percarbonate and sodium perborate). Persalts and bleach activators are included together in powder laundry detergents that contain bleach. In the wash, both compounds dissolve in the water.
One of the active ingredients in OxiClean is sodium percarbonate (Na 2 CO 3 •H 2 O 2), an adduct of sodium carbonate (Na 2 CO 3) and hydrogen peroxide (H 2 O 2). [3] This breaks down into hydrogen peroxide when dissolved in water. These ingredients break down safely in the environment and leave no toxic byproducts. [4]
Reacting trifluoroacetic anhydride with sodium percarbonate, 2Na 2 CO 3 ·3H 2 O 2, yields trifluoroperacetic acid and sodium carbonate, obviating the need for an additional buffer. [5] [12] 3 CF 3 COOCOCF 3 + 4 Na 2 CO 3 · 3 / 2 H 2 O 2 → 6 CF 3 COOOH + 4 Na 2 CO 3 + 3 H 2 O
This is achieved by the action of bleach activators, such as tetraacetylethylenediamine and sodium nonanoyloxybenzenesulfonate, upon hydrogen peroxide formed from sodium percarbonate in water. The peracetic acid is a more effective bleaching agent than hydrogen peroxide itself.
