Sodium hydroxide or NaOH is also famous for the name caustic soda. Iye is the alternate name for caustic soda. It is a corrosive crystalline solid of white colour containing the Sodium or Na+ ions and the Hydroxyl or OH- ions.
1) It can readily absorb the moisture particles until the crystals dissolve.
2) Sodium hydroxide is always the most popular industrial alkali that you can often use for cleaning drains and ovens.
However, it is a highly corrosive chemical to plant and animal tissue.
Is all caustic soda created equal?
A common question among caustic soda suppliers is whether the product will be caustic soda. As you can perceive, caustic soda or sodium hydroxide is an exciting string base. The chemical works as a vital and chief constituent of many industrial procedures for several reasons, including
1) Processing natural gas and petroleum for petroleum products
2) Processing dying synthetic fibres and cotton for the textile industry
3) Pulping and bleaching in the paper industry
4) Saponification of spas and detergents to create more effective detergents and cleaning products.
But all the caustic soda is not the same.
Kinds of caustic soda
The grades and solutions of caustic soda are usually the products of chlorine electrolysis. Typically, the process involves three technologies:
1) Mercury cells
2) Membrane cells
3) Diaphragm cells
Mercury cell:
This production process for caustic soda involves the use of mercury as a cathode for the electrolytic reaction. There will be zero net consumption of mercury during the response, producing the highest purity grade caustic soda with the lowest level of contaminants.
1) It is commercially available.
2) Typically, production of 50-52% y weight of NaOH is possible from mercury cells without extra evaporation.
This is also called Rayon Grade or Mercury Cell Grade.
Diaphragm Cell Grade:
This process of Caustic soda production will include using asbestos or other safer alternatives to separate the co-products- chlorine and caustic soda. The method will typically provide a weak “cell liquor”, which is 12-14% by weight. There will be a need for subsequent evaporation to attain a reasonable concentration of caustic soda (ideally 50%).
The process produces low-quality electrochemical NaOH solutions. Diaphragm Cell Grade or Technical Grade or Commercial Grade or Technical Diaphragm Grade.
Membrane cell Grade
This process is applicable for producing caustic soda using selective membranes that have designs to separate the chlorine ions from the sodium ions. The membranes allow migration of the sodium ions across the elective membrane to keep the chlorine ions and brine on the other side.
The sodium ions will react with the water in mercury to produce the caustic soda, typically 33-35% by weight. But you should not allow a small amount of salt to migrate to the other side, which can cause contamination.
Commercial form: Pellets
If you are searching for caustic soda suppliers for commercial purposes, you must look for caustic soda pellets. These pellets are also called Iye. The shots are strong acid and base neutralizers that can be of perfect use during the staining procedure of the cells. But this is always classified as a dangerous product during transportation, for which the suppliers usually charge an extra shipping amount.
The pellets have various uses, including:
1) Helping in manufacturing pharmaceutical products and medicines like common pain relievers and anticoagulants.
2) Cholesterol reducing medicines also contain the pellets
As the pellets absorb liquids in the earth, dry sand, or similar materials, you need to seal the containers before disposal.
Choose the right supplier.
As you are looking for caustic soda, you must have already understood that there will be a clear distinction in the qualities and grades. Utilize the above knowledge to trace the right manufacturers and suppliers.
