Caustic soda liquid 50%
Caustic Soda Liquid 50% is one of the most widely used chemical compounds in various industries. Due to its unique physical and chemical properties, it plays a very important role in production processes. This substance, also known as Liquid Sodium Hydroxide, Liquid Caustic Soda, or Caustic Soda Lye, is supplied in different packaging options such as tankers, IBC containers, drums, 20-liter cans, and 5-liter cans. The choice of packaging depends on the consumption level and customer requirements.
Physical and Chemical Properties of Caustic Soda Liquid
Caustic Soda Liquid 50% is clear, colorless, and odorless, with a specific gravity of about 1.26 g/cm³. This solution is a mixture of water and sodium hydroxide (NaOH) and is known as a strong alkali in chemical reactions.Physical Properties:
- Melting point: -18 °C
- Boiling point: 188 °C
- Vapor pressure: 0.72 mmHg at 20 °C
- Density: 1.26 g/cm³
- Flash point: 65 °C
- pH: about 14 (strong base)
Chemical Properties:
- High solubility in water with exothermic reaction
- Highly reactive with acids and metals such as aluminum and zinc
- Corrosive and toxic; contact with skin or eyes can cause damage
- Possesses disinfectant, antifungal, and antibacterial properties
Applications of Caustic Soda Liquid in Various Industries
- Oil refining industry: used as a cleaning and separation agent for petroleum compounds
- Chemical industry: in the production and extraction of various chemicals
- Textile industry: for dyeing, washing, and fabric processing
- Polymer industry: in the production of resins, plastics, and polymer raw materials
- Food industry: for oil refining, extract production, and specific applications
- Pharmaceuticals: in extraction, purification, and drug manufacturing processes
- Automotive industry: used as a solvent and cleaning agent in parts manufacturing
- Electronics: for cleaning and producing printed circuit boards
- Cosmetics and hygiene: in the production of soap, shampoo, detergents, and disinfectants
- Detergent industry: as a raw material for dishwashing liquid, laundry detergent, and more
Difference Between Caustic Soda Liquid and Caustic Soda Flakes
Caustic soda flakes (solid caustic soda) appear as a white powder and are solid at room temperature, while caustic soda liquid is an aqueous solution of the same chemical compound with a defined concentration.- Caustic Soda Flakes: concentration expressed in weight percentage (e.g., 99%)
- Caustic Soda Liquid: concentration expressed in molarity (e.g., 1 Molar = 1 mole NaOH per liter of solution)
Factors Affecting the Price of Caustic Soda Liquid
- Supply and demand balance
- Production costs (raw materials, energy, labor)
- Energy price fluctuations
- Geopolitical and trade developments
- Environmental regulations
- Global economic conditions
- Widespread industrial use (aluminum, detergents, pharmaceuticals, etc.)
- Technological advancements
- Regional market developments (such as China and East Asia)
- Seasonal changes (e.g., higher demand during agricultural harvest seasons)
Important Notes When Buying Caustic Soda Liquid
- Ensure product quality and purity
- Select a reliable supplier with proven track record
- Check packaging suitable for consumption needs (IBC, drum, canister)
- Proper storage conditions: in a dry, cool environment away from moisture
- Safe transportation in compliance with hazardous chemicals standards
- Obtain technical data and safety data sheet (MSDS) before use
