Sodium percarbonate CAS NO.15630-89-4

Sodium percarbonate is a chemical, an adduct of sodium carbonate and hydrogen peroxide (a perhydrate), with formula 2Na₂CO₃ · 3H₂O₂. It is a colorless, crystalline, hygroscopic and water-soluble solid. It is used in some eco-friendly cleaning products and as a laboratory source of anhydrous hydrogen peroxide.

Physical properties about Sodium percarbonate are: (1)ACD/LogP: -0.809; (2)ACD/LogD (pH 5.5): -1.98; (3)ACD/LogD (pH 7.4): -3.77; (4)ACD/BCF (pH 5.5): 1.00; (5)ACD/BCF (pH 7.4): 1.00; (6)ACD/KOC (pH 5.5): 1.00; (7)ACD/KOC (pH 7.4): 1.00; (8)#H bond acceptors: 3; (9)#H bond donors: 2; (10)Flash Point:169.8 °C; (11)Enthalpy of Vaporization: 63.37 kJ/moc; (12)Boiling Point: 333.6 °C at 760 mmHg; (13)Vapour Pressure: 2.58E-05 mmHg at 25°C

Preparation of Sodium percarbonate: Sodium percarbonate(CAS NO.15630-89-4) is easily decomposed by water, so it is produced commercially by reacting powdered anhydrous Na₂CO₃ with H₂O₂ dissolved in carbon tetrachloride CCl₄. It can be obtained in the laboratory by reacting the two substances in aqueous solution with proper control of the pH or concentrations.

Uses of Sodium percarbonate: As an oxidizing agent, sodium percarbonate is an ingredient in a number of home and laundry cleaning products, including bleach products such as OxiClean, Tide laundry detergent, and Vanish. It contains no phosphorus or nitrogen. Dissolved in water, it yields a mixture of hydrogen peroxide (which eventually decomposes to water and oxygen) and sodium carbonate ("soda ash").
2Na₂CO₃.3H₂O₂ → 2Na₂CO₃ + 3H₂O₂
Sodium percarbonate can be used in organic synthesis as a convenient source of anhydrous H₂O₂, in particular in solvents that cannot dissolve the carbonate but can leach the H₂O₂ out of it.

When you are using this chemical, please be cautious about it as the following:
1. Keep away from combustible material;
2. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice;
3. Wear eye/face protection;
4. Wear suitable gloves and eye/face protection;
