Magnesium chloride CAS 7786-30-3

What is Magnesium chloride？

Chemical formula MgCl2. The most common one is magnesium chloride hexahydrate, also known as hydrochlorite. Its chemical formula is MgCl2·6H2O, and its formula weight is 203.30. The crystals are colorless monoclinic crystals that are easily deliquescent and have a bitter and salty taste. The density is 1.569g/cm3, the melting point is 118℃ (decomposition), and it is easily soluble in water and ethanol. Above 170°C, basic magnesium chloride and hydrogen chloride are generated. Chemicalbook decomposes into magnesium oxide and hydrogen chloride at 600°C. Anhydrous magnesium chloride is a white shiny hexagonal crystal that is easily deliquescent. Odorless. Has a bitter taste. Relative molecular mass 95.22. Density 2.32g/cm3, melting point 714℃, boiling point 1412℃, slightly soluble in acetone, soluble in water, ethanol, methanol and pyridine. It deliquesces and smokes in moist air, sublimates when white-hot in hydrogen gas flow, easily dissolves in water and releases heat violently.

Application

1. Industrial-grade application: Used as a road ice and snow melting agent. It melts ice quickly, is less corrosive to vehicles, and is less destructive to soil. Its liquid form can be used as road frost protection measures. It is often sprayed on roads before winter rains to prevent them from freezing. Therefore, it can prevent vehicles from skidding and ensure road safety. Magnesium chloride controls dust. It absorbs moisture from the air, so it can be used in dusty areas to suppress dust to the floor, thus preventing small dust particles from spreading in the air. Commonly used in excavation sites, indoor sports venues, horse farms, etc. Storage of hydrogen, this compound can be used to store hydrogen gas. An ammonia molecule is rich in hydrogen atoms. Ammonia can be absorbed by the surface of solid magnesium chloride. Slight heating releases ammonia from the magnesium chloride and generates hydrogen through a catalyst. This compound can be used to make cement. Due to its non-flammable properties, it is often used in various fire protection equipment. The textile and paper industries also take advantage of this. Magnesium chloride is used as a viscosity control agent in cosmetics and skin care products. Softeners and color-fixing agents in detergents. Industrial grade magnesium chloride is a natural decolorizing agent that has a great effect on the decolorization of reactive dyes. As an additive for silica gel products, magnesium chloride modified silica gel can significantly increase the hygroscopic performance. Nutrient for microorganisms in sewage treatment (can promote the activation of microorganisms). The particles in the ink are a moisturizing Chemicalbook agent and a particle stabilizer to improve the vividness of the color. Moisturizer and particle stabilizer for color powders to enhance color vividness. Additives for polishing ceramics can improve surface gloss and strengthen hardness. Raw materials for fluorescent paints. Raw materials for surface insulating coatings on integrated circuit boards.
2. Food-grade application Magnesium chloride can be used as a coagulant for tofu. The tofu is characterized by being tender, smooth and elastic, and has a strong bean flavor. It is a protein coagulant for dried tofu and fried tofu. The dried tofu and fried tofu are not easy to break. Fermentation aid for sake, etc. Water remover (for fish cakes, dosage 0.05% to 0.1%) Texture improver (combined with polyphosphates, used as an elasticity enhancer for surimi and shrimp products), because of its strong bitter taste, the commonly used dosage is less than 0.1%; Mineral fortifier, used in health food and health drinks. Magnesium chloride is also a component of infant formula. In addition, it has been widely used in the production and processing of salt, mineral water, bread, aquatic product preservation, fruits and vegetables and other industries. In food processing, it can also be used as a curing agent, leavening agent, protein coagulant, water remover, fermentation aid, texture improver, etc. It is also used as a nutritional fortifier; a flavoring agent (combined with magnesium sulfate, salt, calcium hydrogen phosphate, calcium sulfate, etc.); a wheat flour treatment agent; a dough quality improver; an oxidizing agent; a modifier for canned fish; and a maltose processing agent.
