Sodium caustic liquid 47%

Liquid Sodium Hydroxide 47% — Sodium Hydroxide Solution

What Is It

Liquid sodium hydroxide is an aqueous solution of sodium hydroxide. It is also commonly referred to as liquid caustic soda, sodium hydroxide solution, or liquid caustic. For this product, the defining characteristics are its liquid form and a NaOH mass fraction of 47%.

Key Characteristics

When Is Liquid NaOH 47% Suitable

Liquid sodium hydroxide 47% is suitable for technological processes in which sodium hydroxide needs to be metered and used as an aqueous solution. It is used in chemical and industrial processes, for pH and alkalinity adjustment, neutralization of acidic media, manufacture of cleaning agents, technological cleaning and degreasing, water treatment and wastewater treatment, and other processes where the use of NaOH solution is specified. The working concentration and dosage should be determined according to the specific process.

Why Choose Liquid NaOH 47%

Liquid sodium hydroxide 47% is already a concentrated aqueous solution. If the process requires NaOH in liquid form, it eliminates the initial step of dissolving granules or flakes, which releases a significant amount of heat.

At the same time, the liquid product contains water, which should be taken into account when considering transportation and the form of supply. A detailed comparison of liquid, granular, and flake NaOH is better covered in a separate Knowledge Center article.

When to Choose Another Form

If dry sodium hydroxide is required, Novohim also offers sodium hydroxide granules 99% and caustic soda flakes. The choice between dry and liquid forms depends on the technological process, dosing method, available equipment, and supply conditions.
Dilution
NaOH solution 47% can be further diluted to the concentration required by a specific technological process. Heat is released during dilution with water, so the applicable process procedure and safety requirements must be followed.

Limitations and Material Compatibility

Sodium hydroxide is a strong alkali and should not be considered universally compatible with all materials. Tanks, piping, pumps, seals, and other equipment in contact with the product should be selected with regard to their chemical resistance to NaOH at the specific concentration and temperature

Storage and Transportation

Liquid sodium hydroxide should be stored and transported in suitable sealed containers in accordance with the requirements applicable to the specific product and method of transport. Containers and equipment should be selected for resistance to concentrated alkaline solutions.

Safety

Liquid sodium hydroxide 47% is a concentrated solution of a strong alkali. Contact with skin, and especially with eyes, can cause severe chemical burns. Appropriate personal protective equipment must be used, and the applicable safety documentation must be followed.

Frequently Asked Questions

What does 47% mean?
It is the mass fraction of sodium hydroxide (NaOH) in the aqueous solution.
Are liquid caustic soda and sodium hydroxide 47% the same product?
In the context of this product page, yes. “Liquid caustic soda” is a common name for a concentrated aqueous sodium hydroxide solution.
What is the practical advantage of the liquid form?
If the process requires NaOH as a solution, the ready liquid form eliminates the initial dissolution of dry granules or flakes, during which a significant amount of heat is released.
Can NaOH 47% be further diluted?
Yes, if a lower concentration is required by the process. Heat generation must be taken into account during dilution, and the applicable safety requirements must be followed.
What packaging is available?
14 kg canister, 50 kg drum, or bulk supply from 500 kg.
Are dry forms of NaOH available?
Yes. Novohim also offers sodium hydroxide granules 99% and caustic soda flakes.
