응용 분야
개요Lanthanum(III) chloride is a relatively stable non-homogeneous catalyst widely used in a variety of organic reactions or transformations. These include the solvent-free preparation of substituted olefins via the Knoevenagel condensation method; the one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones; and as a precursor for the synthesis of La/V co-doped TiO2 nanoparticles via the sol-gel method.
용도Lanthanum chloride is used to prepare other lanthanum salts. The anhydrous chloride is employed to produce lanthanum metal.
일반 설명Lanthanum(III) chloride is white crystalline solid. Gives an amber aqueous solution that can cause destruction or irreversible alterations in human skin tissue at the site of contact. Has a severe corrosion rate on steel.
제조 방법
The heptahydrate is formed by dissolving the oxide, hydroxide or carbonate in hydrochloric acid, followed by crystallization. The anhydrous chloride is obtained by heating oxide, hydroxide, or carbonate in an atmosphere of dry hydrogen chloride. La2(CO3)3 + 6HCl → 2LnCl3 + 3CO2 + 3H2O Another method involves heating lanthanum oxide with excess ammonium chloride at 300°C.
