Hydrochloric Acid,CAS 7647-01-0

Product Introduction

Introduction

We supply high-purity Hydrochloric Acid (CAS No. 7647-01-0), widely used in chemical synthesis, biopharmaceuticals, laboratories, and semiconductor manufacturing. Our products meet international quality standards, cater to high-end application needs, and provide high-performance solutions.

Applications

1. Chemical Synthesis
   • Hydrochloric Acid is widely used in the production of chemicals, including inorganic compounds like sodium chloride, hydrogen chloride, and chlorine. It is also essential in organic chemical synthesis for preparing esters, chlorides, and other organic derivatives.
2. Metal Cleaning and Pickling
   • It is used in industrial cleaning processes to remove rust, scales, and oxides from metals, particularly steel and iron. It dissolves oxides and impurities, preparing metal surfaces for further processing like coating or galvanizing.
3. Water Treatment
   • Hydrochloric Acid plays a key role in water treatment for neutralizing alkaline substances and adjusting pH levels. It is often used in the softening of water, and the treatment of sewage and industrial wastewater.
4. Laboratory Applications
   • AR Grade hydrochloric acid is used in chemical analysis, particularly in atomic fluorescence spectroscopy (AFS) and other analytical techniques. It is essential for preparing standard solutions and in titrations where precise measurements of acids and bases are required.
5. pH Adjustment
   • It is commonly applied in industrial and laboratory processes to lower pH in various chemical reactions and fermentation processes. This helps in controlling the reactivity and the efficiency of chemical reactions.
6. Production of Chlorine and Hydrogen Chloride Gas
   • Hydrochloric Acid is used in the production of chlorine gas through the reaction with sodium chloride. It also serves as a precursor to hydrogen chloride gas, which is a vital component in the synthesis of various chemicals.

Preparation

1. AR Grade (Analytical Reagent)
   • Purification: The AR Grade hydrochloric acid undergoes multiple purification stages to ensure minimal contamination. This typically involves distillation and filtration to reduce impurities such as metal ions, bromine, and other halogens.
   • Quality Control: The final product is rigorously tested for purity, ensuring that the metal ion content is below 1ppm and the bromine level is minimized.
   • Packaging: The acid is carefully packaged in sealed, contamination-free containers to preserve its purity and avoid exposure to air, which could lead to acid concentration changes.
2. GR Grade (Guaranteed Reagent)
   • Purification: GR Grade hydrochloric acid is subjected to rigorous purification processes, including ion exchange and recrystallization, to remove impurities and ensure consistent quality.
   • Quality Control: This grade undergoes strict quality control measures, particularly focusing on sulfur and metal ion levels to ensure suitability for industrial and high-quality research applications.
   • Packaging: Packaged in large drums or bottles under controlled conditions to maintain its stability.
3. Industrial Grade
   • Purification: Industrial Grade hydrochloric acid typically undergoes less rigorous purification compared to AR and GR grades. It is produced with a focus on large-scale production for industrial applications, where high purity is not as critical.
   • Concentration: This grade is often available in concentrations such as 18-20%, 30%, or 36-38% to meet specific industrial needs, such as metal cleaning or pH control.
   • Packaging: Available in large drums (25Kg or 200Kg) or bulk containers suitable for industrial usage.
4. Customized Grade
   • Purification: Tailored to specific customer requirements, the Customized Grade may include specific formulations like low bromine or reduced metal ion content.
   • Quality Control: This grade is produced according to customized standards, with strict adherence to specified levels of purity, often requiring additional purification techniques.
   • Packaging: Flexible packaging options based on customer requirements, including bulk containers or smaller bottles.
