Chemical formula H3BO3 boric acid, elemental form of a tube of a oksiasi kimyasaldır.türkiye boric acid, colemanite üretilmektedir.üret from my process basically consists in inserting the reaction with colemanite sulfuric acid. As shown below, the reaction results from gypsum and boric acid. Gypsum produced during production causes environmental pollution. H3 BO3, or anhydrous boron oxide. used as cooling water in nuclear reactors. Properties Boric Acid is odorless, tasteless, air stable, white crystals. Boric acid is moderately soluble in water. the solubility in hot water is higher than in cold water. soluble in alcohol and glycerin. Boric acid is a very weak mono-basic acid, which acts as a lewic acid and has a hydroxyl ion. The value of boric acid, which is also used in LCD television and mobile phones, is increasing day by day.
Production and Reactions
In the laboratory, boric acid is obtained from the hydrolysis of boron halides. For commercial purposes, boric acid is obtained by the addition of chloride or sulfuric acid to the borax solution. Commercial boric acid has a purity of 99.9%. In general, its synthesis in chemistry may occur according to the following reaction.
Ca2B6O11.5H2O 2H2SO4 6H2O? 2caso4. 2H2O 6H3BO3
In the presence of H2SO4 as a water absorbant in boric acid environment, it forms borate esters with alcohols.
B (OH) 3 3CH3OH? B (OCH 3) 3 3H 2 O
(Boric Acid) (Alcohol) (Borate Esters)
The ionization reaction of boric acid in water is as follows.
B (OH) 3 2 H 2 O H 3 O [B (OH) 4] B
If boric acid is reacted with sodium peroxide, the peroxoborate used in trade as bleach is obtained.
Reacts with certain polyalcohols such as glycerin and gives acidic chelate complexes. When metal is melted with oxides it gives highly colored glassy borates which characterize the real metal ions. This event is used in the analysis of metal ions. If boric acid is heated up to 175 ° C, metaboric acid takes the form of HBO2 by losing water. When heated more, tetraboric acid H2B4O7 occurs. In fact, it becomes a glassy boron trioxide when it is warmed up. The production of boric acid by using decahydrate was carried out on a laboratory scale. In addition, considering the density of the solutions in industrial applications, boric acid production values ??were obtained by using the concentrated solution with a density of 1240 g / l and a weak solution with a density of 1180 g / l. The boric acid was subjected to the refining process and the production of boric acid with low purity was carried out.
Used to prevent damage to skin care products. It is one of the best ingredients in cleaning oily skin.
Aqueous solutions are used in mouthwashes, eye drops, skin lotions and cosmetics. Used as an antiseptic agent and emulsifier.
Provides great benefit in removing unwanted odors in the body and in the absence of fungi
It is the most effective method for the cleaning of heating insects.
It is used in the construction of orthoborate used in fertilizer or in the production of pesticides for the cleaning of unwanted weeds.
Heat resistant glass is used in fireproof fabrics, electrolysis baths, leather production, porcelain polishing and steel hardeners. Ointments, mouthwashes, eye drops, bath salts, creams and shampoos are used. It is used as electrolyte in nickel plating.
