Caustic Soda Export Supply Solutions

Caustic soda or sodium hydroxide is a white solid substance with the chemical formula of NaOH and it is resulted from the process of electrolysis of sodium chloride soluble in the electrolytic vessels. It is called caustic soda because it is highly corrosive in nature. It is available in many forms in the industry, and the most common forms are caustic soda flakes and caustic soda pearls. Pure Caustic soda is a colorless crystalline solid that melts at 318 °C without decomposition. It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol.
Similar to the hydration of sulfuric acid, dissolution of caustic soda flakes in water is a highly exothermic reaction where a large amount of heat is released, posing a threat to safety through the possibility of splashing. The resulting solution is usually colorless and odorless. As with other alkaline solutions, it feels slippery with skin contact due to the process of saponification that occurs between NaOH and natural skin oils.
Caustic soda 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 hydroxide is most commonly sold as flakes, pills, and cast blocks
