Sodium Hydroxide | Medical Management Guidelines
At room temperature, anhydrous sodium hydroxide is a white crystalline, odorless solid that absorbs moisture from the air. It is produced as flakes, pellets, sticks, and cakes. When dissolved in water or neutralized with acid, it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is caustic and is one of …
A clean production process of sodium chlorite from sodium chlorate
Production of sodium chlorite with a reducing agent consists of two steps: (1) preparation of chlorine dioxide by reacting sodium chlorate in sulfuric acid, and then (2) reaction of chlorine dioxide with a reducing agent in sodium hydroxide solution. The first step is the key to determine product economics and production technology.
