Sodium hydroxide, also known as lye and caustic soda, [1] [2] 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 hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
The main types of irritant and/or corrosive products are: acids, bases, oxidizers / reducing agents, solvents, and alkylants. Additionally, chemical burns can be caused by biological toxins (such as anthrax toxin) and by some types of cytotoxic chemical weapons, e.g., vesicants such as mustard gas and Lewisite, or urticants such as phosgene oxime.
Caustic most commonly refers to: Causticity, the property of being able to corrode organic tissue. Sodium hydroxide, sometimes called caustic soda; Potassium hydroxide, sometimes called caustic potash; Calcium oxide, sometimes called caustic lime; Caustic may also refer to: Caustic (band), an American industrial/powernoise band
Solvent-base paint strippers can be complex mixtures of various organic solvents, emulsifiers, thickening agents, alkaline or acid active ingredients as well as evaporation and corrosion inhibitors. Dichloromethane , also called methylene chloride, is a popular solvent, but its use has been declining because of health concerns. [ 1 ]
A corrosion inhibitor or anti-corrosive is a chemical compound added to a liquid or gas to decrease the corrosion rate of a metal that comes into contact with the fluid. [1] The effectiveness of a corrosion inhibitor depends on fluid composition and dynamics .
Liquid bleach, often called just bleach, is a common chemical household product that consists of a dilute solution of sodium hypochlorite (NaClO) and other secondary ingredients. It is a chlorine releasing bleaching agent widely used to whiten clothes and remove stains, as a disinfectant to kill germs , and for several other uses.
Chlorine gas exiting the cell line must be cooled and dried since the exit gas can be over 80°C and contains moisture that allows chlorine gas to be corrosive to iron piping. Cooling the gas allows for a large amount of moisture from the brine to condense out of the gas stream. Cooling also improves the efficiency of both the compression and ...
Chlorine is produced from sodium chloride (common salt, NaCl) using electrolysis to separate metallic sodium from chlorine gas. Usually salt is dissolved in water to produce a brine. By-products of any such chloralkali process are hydrogen (H 2) and sodium hydroxide (NaOH), which is commonly called caustic soda or lye.
