Barium Carbonate (BaCO₃): Properties, Production, Applications, and Safety

图片
  1. Introduction Barium Carbonate (BaCO₃) is an inorganic compound widely used in industries such as ceramics, glass, and chemicals. It is a white, odorless powder with limited solubility in water but soluble in acids. This article explores its properties, synthesis methods, applications, and safety measures in exhaustive detail. 2. Physical and Chemical Properties 2.1 Physical Properties Molecular Weight: 197.34 g/mol Appearance: White crystalline solid (rhombic or alpha form at room temperature) Density: 4.286 g/cm³ Melting Point: 811°C (decomposes to BaO + CO₂) Solubility: 0.002 g/100 mL (water, 20°C) Soluble in acids (e.g., HCl, HNO₃) 2.2 Chemical Properties Thermal Decomposition: BaCO3→ΔBaO+CO2↑ BaCO3ΔBaO+CO2↑ Reaction with Acids: BaCO3+2HCl→BaCl2+H2O+CO2↑ BaCO3+2HCl→BaCl2+H2O+CO2↑ Conversion to Barium Sulfate: BaCO3+H2SO4→BaSO4+H2O+CO2↑ BaCO3+H2SO4→BaSO4+H2O+CO2↑ 3. Production Methods 3.1 Carbonation Process Barium sulfide (BaS) solution is treated with CO₂: BaS+H2O+CO2→BaC...

What are the chemical components of Sophora flavescens

图片
Matrine  Sophora flavescens Chemical composition As early as the early 1930s, the Soviet Union began to study it abroad, and China began in 1972. The focus of research at home and abroad is on alkaloids. The alkaloids extracted, separated and identified from Sophora flavescens plants in China mainly include oxymatrine (C15H24N2O2), matrine (C15H24N2O), isomatrine (Iosmatrine, C15H24N2O), hydroxymatrine (sophor-anol), sophocarpine (C15H22N2O), N-oxysophocarpine (C15H22N2O2), sophoramine, sophoridine (Sophoridine, C15H24N2O), Aloperine, sparteine, N-methylcytisine, anagyrine, bap-iifoline, sophocarpine, d-matrine, d-isomatrine, d-oxymatrine, l-anagyrine, l-methyleytisine, l-baptifoline, kurarid-in, sophoranol (C15H24N2O2), sophoranhol N-oxide (C15H24N2O3), N-methylcytisine (C12H16N2O), and other alkaloids. Flavonoids: The flavonoids contained in Sophora flavescens are mostly dihydroflavones and dihydroflavonols, and there are also flavones, isoflavones, chalcones, etc. The flavonoids...
