Poor quality crude oil can be treated with sodium hydroxide to remove sulfurous impurities in a process known as caustic washing. As above, sodium hydroxide reacts with weak acids such as hydrogen sulfide and mercaptans to yield non-volatile sodium salts, which can be removed. Meer weergeven Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na and hydroxide anions OH . Sodium … Meer weergeven Sodium hydroxide is industrially produced as a 50% solution by variations of the electrolytic chloralkali process. Chlorine gas is also produced in this process. Solid sodium hydroxide is obtained from this solution by the evaporation of water. Solid sodium … Meer weergeven Like other corrosive acids and alkalis, drops of sodium hydroxide solutions can readily decompose proteins and lipids in living tissues Meer weergeven Sodium hydroxide was first prepared by soap makers. A procedure for making sodium hydroxide appeared as part of a recipe for … Meer weergeven Physical properties Pure sodium hydroxide is a colorless crystalline solid that melts at 318 °C (604 °F) without decomposition and with a boiling point of 1,388 °C (2,530 °F). It is highly soluble in water, with a lower solubility in Meer weergeven Sodium hydroxide is a popular strong base used in industry. Sodium hydroxide is used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. In bulk, it is most often handled as an aqueous solution, since solutions are cheaper and … Meer weergeven Careful storage is needed when handling sodium hydroxide for use, especially bulk volumes. Following proper NaOH storage guidelines and maintaining worker/environment … Meer weergeven WebSodium hydroxide storage tanks are manufactured from HDPE, XLPE, carbon steel, and FRP to 1.9 specific gravity. Secondary containment is required for bulk applications. NaOH is stable long term. Storing above …
