Herstellung Von Stickstoff-Calcium-Düngern Auf Der Basis Von Magnesiumhydroxid

The monograph addresses the topic 'The Modern State of Production of Magnesium Hydroxide and Liquid Nitrogen-Calcium Fertilizers,' detailing the history, properties, and conditions for the production of substances such as magnesium hydroxide and magnesium carbonate, acrylonitrile, polyacrylonitrile, vinyl acetate, polyvinyl acetate, dimethylformamide, etc. It also provides information about their production using available technologies and raw materials. The primary raw materials for the production of magnesium oxide are two natural minerals: magnesium carbonate (magnesite, MgCO3) and magnesium chloride hexahydrate (bischofite, MgCl2 6H2O). Based on experiments, information is provided about the mineral carnallite (MgCl2.KCl 6H2O) as a natural raw material for the extraction of high-purity magnesium oxide. The method for obtaining magnesium hydroxide from magnesium chloride solutions involves treating them with monoethanolamine, exposing the suspension to a constant electric field, and then filtering and washing the resulting magnesium hydroxide suspension. The monograph can serve as a reference work for relevant educational fields.
