Boric acid, is an inorganic compound, chemical formula for H3BO3, white crystalline powder, smooth feel, no smell, a large number of glass industry, can improve the heat resistance of glass products, transparent performance, improve mechanical strength, shorten the melting time, can also be used as antiseptic, disinfectant.
Boric acid is a very weak acid, the source of its acidity is not itself to give protons, because boron is an electron-deficient atom, can add water molecules of hydroxide ions, and the release of protons. Taking advantage of this electron-deficient property, the addition of polyhydroxy compounds (such as glycerol alcohol and glycerol, etc.) to generate stable complexes to enhance their acidity.
When glycerol is added to boric acid, esterification reaction will occur, which will reduce the concentration of borate ions and promote the ionization of boric acid, so the acidity of the solution will be enhanced.
