Hydrochloric Acid 37% Premium ACS Reagent Grade

Description

Hydrochloric Acid 37% is a highly concentrated, colorless to slightly yellow liquid with a pungent odor. It is a strong and corrosive mineral acid widely used in industrial processes, water treatment, chemical manufacturing, and food production. Hydrochloric Acid plays a critical role in pH control, metal cleaning, and the production of various organic and inorganic compounds.

Applications:

Industrial Applications:

• Steel Pickling: Hydrochloric acid is widely used in the steel industry to remove rust, scale, and other impurities from iron or steel before further processing like galvanizing, coating, or extrusion. The acid helps prepare the metal surface for treatments.
• pH Control and Neutralization: It is used to regulate the pH in various industrial processes, such as wastewater treatment, manufacturing of chemicals, and other production operations where precise pH levels are critical.
• Chemical Synthesis: Hydrochloric acid is a raw material in the production of a wide range of organic and inorganic compounds, including vinyl chloride (used to make PVC), fertilizers, dyes, and detergents.
• Oil and Gas Industry: It is used in well acidizing operations to clean and stimulate oil and gas wells. The acid dissolves carbonate rock and helps improve the flow of oil and gas from the reservoir to the wellbore.

Food and Beverage Industry:

• Food Processing Additive (E507): Hydrochloric acid is approved as a food additive, mainly for pH adjustment. It is used in the processing of various food products such as sauces, canned vegetables, and soft drinks to control acidity and preserve freshness.
• Protein Hydrolysis: In the production of gelatin and collagen from animal bones and hides, hydrochloric acid is used to break down proteins and produce amino acids, which are used as ingredients in food and pharmaceuticals.

Water Treatment:

• pH Adjustment in Water Treatment: Hydrochloric acid is used in the treatment of drinking water and industrial wastewater to lower pH levels, making the water more suitable for specific treatments. It helps neutralize alkaline water in municipal water treatment plants.
• Scale and Deposit Removal: The acid is effective in removing scale, mineral deposits, and rust from equipment and pipelines in water treatment facilities, industrial boilers, and cooling towers.

Pharmaceutical Industry:

• pH Control in Drug Formulation: Hydrochloric acid is commonly used to adjust the pH of solutions in pharmaceutical production. It plays a role in the synthesis of active pharmaceutical ingredients (APIs) and is used to produce many over-the-counter (OTC) medicines and treatments.
• Chemical Intermediate: It is involved in the production of pharmaceutical compounds, particularly in the synthesis of salts and pH modifiers for medicinal products.

Cleaning and Household Products:

• Household Cleaners: Hydrochloric acid is an ingredient in toilet bowl cleaners, tile cleaners, and other household products due to its ability to dissolve stains, mineral deposits, and dirt. It is particularly effective for cleaning tough stains like calcium carbonate and lime buildup.
• Industrial Cleaning: Used in heavy-duty industrial cleaning applications to remove rust, scale, and other deposits from machinery, boilers, and heat exchangers.

Construction Industry:

• Concrete Cleaning and Etching: Hydrochloric acid is used to clean and etch concrete surfaces, preparing them for painting, sealing, or coating. It helps to remove surface contaminants and open up pores for better adhesion of finishes.
• Brick Cleaning: It is also employed to clean brickwork, removing mortar stains and efflorescence (white salt deposits) from new constructions.

Textile and Leather Processing:

• Dyeing and Bleaching: Hydrochloric acid is used to control the pH during the dyeing and bleaching process in the textile industry, ensuring that dyes bond properly with fabrics and preventing color inconsistencies.
• Leather Processing: In the leather tanning industry, hydrochloric acid is used in the deliming and tanning stages to neutralize alkaline conditions, facilitating the treatment of animal hides.

Laboratory Use:

• Laboratory Reagent: Hydrochloric acid is widely used in analytical and research laboratories as a reagent for chemical reactions, titrations, and the preparation of buffer solutions.
• Sample Preparation: It is also used in the digestion of samples for elemental analysis, particularly in the preparation of minerals and metals for chemical analysis.

Metallurgy:

• Metal Processing: In the mining and metallurgical industries, hydrochloric acid is used for the extraction of metals such as molybdenum, tantalum, and rare earth elements. It is also utilized in the refining and purification of various metals.
• Metal Cleaning and Etching: Used for cleaning and preparing metal surfaces in the automotive and aerospace industries, hydrochloric acid removes oxidation and prepares metals for coating or bonding.

Storage and Handling:

• • Storage Conditions: Store in a cool, dry, well-ventilated area away from direct sunlight and incompatible materials such as strong bases, organic materials, and metals.
  • Container Materials: Store in corrosion-resistant containers such as HDPE, PVC, or rubber-lined steel tanks.
  • Spill Containment: Ensure secondary containment for spill control and prevention.
  • Handling: Use appropriate Personal Protective Equipment (PPE), such as gloves, goggles, face shields, and chemical-resistant clothing.

Safety Information:

• Hazard Class: Corrosive (Class 8)
• UN Number: 1789
• Personal Protective Equipment (PPE): Requires gloves, goggles, face shields, and proper ventilation.
• First Aid:
  • Skin/Eye Contact: Immediately rinse with water for at least 15 minutes and seek medical attention.
  • Inhalation: Move to fresh air and seek medical attention if respiratory symptoms occur.
