What is boric acid?
1.) Boric acid is a crystalline compound formed by three oxidation of two boron and dissolved in water. It belongs to inorganic acid, mainly four boric acid H2B4O7 (also called boric acid), boric acid (HBO2) n and boric acid H3BO3 (also known as boric acid). Among them, boric acid has the largest moisture content and the most stable. Boric acid, also referred to as boric acid, appears as a white powder crystalline or three oblique surface scale shaped knot crystal with luster. Have a slight bitter taste. Soapy in contact with skin. No odor, soluble in water, ethanol, glycerol, ethers and essential oils, water solution has a weak acid, boric acid is heated to 70-100 DEG C gradually dehydrated into boric acid, 150 DEG -160 DEG at 300 DEG C into coking boric acid, boric anhydride (B2O3). Boric acid is toxic to humans. Solubility in water: at 0, 2.77, 10, 3.65, 20, 4.87, 25, 5.74, 30, 6.77, 40, 8.90, 50, 11.39, 60, 14.89, 80, 23.54, 100, 38. The aqueous solution is weakly acidic and is a typical Lewis acid, which can promote solubility in water when hydrochloric acid, citric acid or tartaric acid exist. Therefore, recrystallization can be used to purify. Boric acid with sulfuric acid applied to the solution of heat can be prepared boric acid: Na2B4O7+H2SO4+5H2O=Na2SO4+4H3BO3, cooling crystallization can be precipitated.
2.) Northeast China is rich in boron, magnesium ore, MgB2O5, H2O or 2MgO, B2O5, H2O. Direct decomposition of magnesium borate with sulfuric acid can also be made from boric acid: Mg2B2O5 = H2O+2H2SO4 = 2MgSO4+2H3BO3.
When boiling boric acid, a part of boric acid is vaporized at the same time as water vapor, so water vapor from cracks in volcanic formations often contains boric acid.
Boric acid is mainly used in glass products, especially in heat resistant and chemical resistant glass products. Boron carbide made from boric acid; used as an abrasive. In addition, it can be used in enamel, ceramic glaze, medicine and inorganic pigment, fertilizer and metallurgical production.
Boric acid use
1. pH value regulator, disinfectant, bacteriostatic preservative, etc.
2. preparing borate, boric acid ester, optical glass, paint, pigment, boric acid soap, leather finishing agent, dyeing auxiliaries and medicine disinfectant
Applications in capacitor manufacturing and electronic component industries, high purity analytical reagents, pharmaceutical disinfection, corrosion protection and preparation of exposed photosensitive materials, rinsing and processing liquid medicine.
3. used in glass, enamel, ceramics, medicine, metallurgy, leather, dyestuff, pesticide, fertilizer, textile and other industries
4.use are formulated with buffers and various borates, and various mediums are prepared in haploid breeding.
5.it as PH regulator, bacteriostatic preservative.
6.As chromatographic analytical reagent, also used in the preparation of buffers
A large number of uses for glass (glass, acid glass, heat-resistant glass, insulating glass fiber optics) industry, can improve the glass heat resistant, transparent performance, improve mechanical strength, shorten the melting time. In enamel and ceramics, it is used to strengthen the gloss and fastness of enamel products. It is also one of the ingredients of glazes and pigments. The metallurgical industry as additives, solvents, especially the steel has high hardness and good ductility can replace nickel steel rolling. Boric acid has antiseptic properties and can be used as preservatives, such as wood preservatives. They are used in industries such as metal welding, leather, photography, as well as dyes, heat resistant fire retardant fabrics, artificial gemstones, capacitors, and cosmetics. It can also be used as pesticides and catalysts. Agricultural boron containing microelement fertilizer, fertilizer for many crops, can improve crop quality and yield. Boric acid is also one of the basic materials for producing other boride, and boron compounds produced by it are widely used in national defense and other industrial departments and scientific research units.
