| Boric acid is boron oxide hydrate (B2O3.3H2O), white crystalline powder or triclinic axial shiny scale-like crystal, there are creamy feel, no odor. Proportion of 1.435 (15 º C). Soluble in water, alcohol, glycerol, ethers and essential oils, the aqueous solution was weakly acidic. Boric acid in water solubility with increasing temperature and water vapor with evaporation; in the solubility of inorganic acid in water solubility than small. Heated to 70 ~ 100 º; C gradually generate partial dehydration of boric acid, 150 ~ 160 º; C Jiao generate boric acid, 300 º; C generate boric acid anhydride (B2O3). Boric acid toxic to humans, the nerve center of internal influence. Is not itself the source of the acidic proton is given, as is electron deficient boron atom, water molecules together can increase the hydrogen ion, and proton release. Electron deficient nature of this by adding polyols (such as glycerol and other alcohols and glycerol) to form a stable complex in order to strengthen its acidity. Boric acid is used extensively for the glass (optical glass, acid-resistant glass, heat-resistant glass, glass fiber insulation materials) industry, to improve the heat-resistant glass, tran***rent performance, increase mechanical strength, to shorten the melting time. |
