硼酸 (CAS No.11113-50-1)
- 物化性质
- 白色三斜轴面鳞片状带光泽晶体。相对密度1.435，折射率1.337、1.461、1.462。溶于水、乙醇和甘油，水溶液呈酸性，为一元弱酸（Ka=6×10⁻¹⁰）。溶解度随温度升高而增大。加热至169°C（±1°C）脱水生成偏硼酸，300°C生成硼酸酐。与强碱中和得偏硼酸盐，在碱性较弱条件下得到四硼酸盐。

Product Name:Boric Acid
English Name:Boric Acid
CAS No.:11113-50-1
Aliases:Orthoboric acid, Boracic acid, Hydrogen borate
Molecular Formula:H3BO3
Physical Properties:White triclinic axial scale-like lustrous crystals. Relative density 1.435; refractive indices 1.337, 1.461, 1.462. Soluble in water, ethanol, and glycerol; aqueous solution is acidic, a monobasic weak acid (Ka=6×10⁻¹⁰). Solubility in water increases with temperature. Heated to 169°C (±1°C), it dehydrates to metaboric acid; at 300°C, boric anhydride is formed. Neutralization with strong bases yields metaborates; under weakly alkaline conditions, tetraborates are obtained.
Uses:Widely used in the production of borates, water glass, borate esters, optical glass, ceramic glaze, paints, pigments, cosmetics, food preservatives, leather finishing agents, textile printing and dyeing auxiliaries, and pharmaceuticals. It is also used as an antiseptic disinfectant and astringent.
Technical Specifications:
Purity: 98.5%
Molecular weight: 61.83
EINECS No.: 233-139-2
Appearance: white triclinic axial scale-like lustrous crystals
Solubility: soluble in water, ethanol, and glycerol; aqueous solution is weakly acidic
