Flake Boric Acid
CAS No.: 11113-50-1
Molecular formula: bh3o3
Molecular weight: 61.83
EINECS No.: 234-343-4
Boric acid is also called "normal boric acid". It is obtained by the reaction of natural borax (sodium borate) with acid. Chemical formula H3BO3. Molecular weight 61.83. White triaxial scales with shiny crystals. The relative density is 1.43514 and the refractive index is 1.337, 1.461 and 1.462. Soluble in water, ethanol and glycerol. The aqueous solution is acidic and monobasic weak acid (KA = 6) × 10-10)。 The solubility in water increases with the increase of temperature. Heat to 16chemicalbook 9 ℃ (± 1 ℃) and dehydrate to form metaboric acid, and form boric at 300 ℃. Metaborate is obtained by neutralization with strong base. Tetraborate was obtained under weak alkaline conditions. Preparation method: it can be prepared by adding hydrochloric acid or sulfuric acid to borax solution or decomposing cristobalite by hydrochloric acid. Uses: it is widely used in making borates, water glass, borates, optical glass, enamel, paint, pigment, cosmetics, food preservatives, leather finishing, printing and dyeing additives and medicine.
