PRODUCTION NITROGEN-CALCIUM FERTILIZERS BASED ON MAGNESIUM HYDROXIDE. MONOGRAPHY

      Аннотация: Since the monograph is on the subject of "The modern state of the field of production of magnesium hydroxide and liquid nitrogen-calcium fertilizers", the history, properties, and conditions of production of substances such as magnesium hydroxide and magnesium carbonate, acrylonitrile, polyacrylonitrile, vinyl acetate, polyvinyl acetate, dimethylformamide, etc. information about its production using technology, among available raw materials. The main raw materials for the production of magnesium oxide are two natural minerals: magnesium carbonate (magnesite, MgCO3) and magnesium chloride hexahydrate (bisulfite, MgCl2∙6H2O). Information about the mineral carnallite (MgC12.KC1∙6H2O) as a natural raw material for obtaining high-purity magnesium oxide is given based on experiments. The method of obtaining magnesium hydroxide from magnesium chloride solutions involves treating them with monoethanolamine, exposing the suspension to a constant electric field, filtering the resulting magnesium hydroxide suspension, and washing it.The monograph can be used as a reference for relevant educational areas.
