Lanthanum Chloride Heptahydrate Powder is a colourless and transparent white crystalline powder with the chemical formula LaCl₃・7H₂O, hygroscopic, easily soluble in water, commonly used in petroleum catalysts, water treatment, biochemical research, organic synthesis and other fields.
Properties
Molecular weight: 371.371 g/mol
Density: Relative density of lanthanum chloride heptahydrate is 2.23 g/cm³ (different from that of anhydrous lanthanum chloride 3.84 g/ml (25℃)).
Melting point: 91°C (gradually loses water of crystallisation and decomposes when heated).
Appearance: Lanthanum Chloride heptahydrate is usually white crystalline powder or lumpy solid, with a certain degree of recognition in appearance.
Solubility: Soluble in water, with high solubility in water, the dissolution process releases a certain amount of heat. At the same time, it can also be dissolved in alcohols and other organic solvents, but the solubility is relatively small in water.
Hygroscopicity: Lanthanum Chloride Heptahydrate has strong deliquescence and easily absorbs moisture in the air, so it needs to be sealed during storage and use to prevent moisture from affecting its performance.
Stability: It is relatively stable at room temperature and pressure, but will undergo chemical reactions when heated or encountering certain specific conditions. For example, when heated, it will gradually lose the water of crystallisation and may undergo hydrolysis to produce lanthanum chlorohydrate and other substances.
Acidity: Aqueous solutions of lanthanum chloride heptahydrate are acidic because lanthanum chloride is partially hydrolysed in water to produce hydrogen ions.
Coordination: Lanthanum ions have a strong coordination ability and can form stable complexes with a number of ligands, a property that has important applications in chemical synthesis and materials preparation.
Applications
Petrochemical field: It can be used in the manufacture of petroleum cracking catalyst, which can improve the efficiency of petroleum cracking and the quality of products, and has an important role in the petrochemical industry.
Water treatment field: In sewage treatment, lanthanum chloride heptahydrate can be used as a kind of flocculant or precipitant to remove phosphate and other harmful substances in water, which can effectively purify water quality.
Optical materials: doping into certain optical materials can improve the optical properties of the materials, such as improving the refractive index and luminous efficiency of the materials, etc. It has application value in the preparation of optical glass, optical fibres and other materials.
Magnetic materials: the unique electronic structure of lanthanum makes it useful in the preparation of magnetic materials, and lanthanum chloride heptahydrate can be used as the precursor material for the preparation of magnetic materials.
Biomedical field: It can be used as anticoagulant and anti-atherosclerosis drugs in medicine, and also has certain applications in biochemical research.
Other fields: It can be used as one of the proportioning materials of nano-fluorinated rare earth lubricant additives, which can improve the performance of lubricant. In the laboratory, lanthanum chloride heptahydrate is also a commonly used chemical reagent for various chemical experiments and analytical tests.
