Product Information

Sodium Sulfide

Sodium Sulfide (CAS Number: 1313-82-2) Supplier in Europe

Physical Details and Properties

Sodium sulfide is a yellow or red crystalline solid with a chemical formula of Na₂S and a molecular weight of 78.04 g/mol. It is highly soluble in water and hygroscopic, readily absorbing moisture from the air. Sodium sulfide is commercially available in different concentrations, including 60% and 62%.

Production Methods

At SoleChem Chemicals, we ensure a reliable supply of high-quality sodium sulfide. The primary production method involves the reaction of sodium hydroxide (NaOH) with hydrogen sulfide (H₂S) gas. This reaction produces sodium sulfide, which can be further processed and purified to obtain the desired concentration.

Industrial Applications

Sodium sulfide finds diverse applications in various industries across Europe. Let’s explore some of its key uses:

  1. Textile Industry: Sodium sulfide is utilized in the textile industry for various processes, including dyeing and dehairing. It acts as a reducing agent and assists in the removal of impurities and unwanted materials from fabrics and fibers. It helps in achieving uniform dyeing and enhancing the quality of textile products.
  2. Paper and Pulp Industry: Sodium sulfide is used as a bleaching agent in the paper and pulp industry. It helps remove lignin, a natural polymer that colors wood pulp. Sodium sulfide is employed in the kraft process, contributing to producing high-quality paper products.
  3. Leather Industry: Sodium sulfide plays a crucial role in the leather industry during dehairing and deliming hides. It helps remove hair and unwanted substances from animal hides, preparing them for further processing and tanning.
  4. Chemical Manufacturing: Sodium sulfide is a reagent and precursor in various chemical reactions. It is used to produce other sodium compounds, sulfur dyes, and organic chemicals. Sodium sulfide finds application in manufacturing rubber chemicals, flotation agents, and wastewater treatment chemicals.

Safety Information

When handling sodium sulfide, it is important to follow proper safety precautions:

  1. Handling and Storage: Store sodium sulfide in a cool, dry place, away from moisture and incompatible substances. When handling the chemical, use appropriate personal protective equipment, such as gloves and goggles.
  2. Health Hazards: Sodium sulfide is corrosive and can cause severe skin and eye irritation. Inhalation of dust or vapors can also irritate the respiratory system. Avoid direct contact and inhalation. In case of contact, rinse affected areas with water and seek medical attention if necessary.
