Acetic Acid, scientifically known as ethanoic acid and identified by CAS number 64-19-7, is a fundamental organic compound with a wide spectrum of applications across industries. From its common use in vinegar to its critical role in chemical synthesis, understanding its properties and sourcing is key for professionals in research and manufacturing. This article explores the essential characteristics and applications of Acetic Acid, guiding you on how to effectively buy acetic acid and identify a reliable acetic acid supplier.

Chemical Profile of Acetic Acid

Acetic Acid is a colorless liquid with a distinctive pungent, vinegary odor. Its chemical formula is CH3COOH. It is a weak monoprotic acid, with a pKa of around 4.76, making it moderately acidic. Key properties include:

  • Appearance: Colorless liquid.
  • Odor: Pungent, vinegary.
  • Purity: Available in various grades, with glacial acetic acid being the highly pure, anhydrous form (>99.7%).
  • Solubility: Miscible with water, ethanol, and ether.
  • Boiling Point: Approximately 118°C.
  • Melting Point: Approximately 16.6°C (for glacial acetic acid).

The availability of different grades, such as glacial acetic acid 99.8%, caters to specific industrial requirements.

Diverse Industrial Applications of Acetic Acid

Acetic acid's utility spans numerous sectors:

  • Chemical Manufacturing: It is a crucial intermediate in the production of vinyl acetate monomer (VAM), acetic anhydride, and various acetate esters used in polymers, paints, adhesives, and solvents.
  • Textiles: Used in dyeing processes and the production of cellulose acetate fibers.
  • Food Industry: As a food additive (E260), it acts as an acidity regulator, preservative, and flavor enhancer.
  • Pharmaceuticals: It has antiseptic properties and is used in some medical treatments and formulations.
  • Laboratory Use: Employed as a solvent, reagent, and in titrations.

The demand for reliable sourcing of this chemical is consistently high.

Sourcing and Purchasing Acetic Acid

When looking to procure Acetic Acid, especially in bulk, consider these factors:

  • Supplier Reputation: Choose suppliers with a strong reputation for quality, consistency, and reliable delivery.
  • Certifications: For food or pharmaceutical applications, ensure the supplier provides appropriate certifications.
  • Pricing: Compare the industrial grade acetic acid price from various manufacturers. Suppliers in China often offer competitive rates for bulk purchases.
  • Technical Data: Always request the Safety Data Sheet (SDS) and Certificate of Analysis (COA) for the product.

Engaging with a dedicated acetic acid manufacturer or a reputable distributor ensures you receive a product that meets your specifications. If you're seeking to purchase acetic acid for industrial use, focusing on a supplier that offers both quality and competitive pricing for bulk acetic acid is a strategic approach.

By understanding the properties and applications of Acetic Acid (CAS 64-19-7) and working with trusted partners, businesses can ensure the seamless integration of this vital chemical into their operations.
