ACETIC ACID IN NAIROBI, KENYA

Olinc Industrials Ltdare the leadings suppliers of Acetic acid in Nairobi, Kenya (CH3COOH). Acetic Acid  is the most important of the Carboxylic Acids. A dilute (approximately 5 percent by volume) solution of acetic acid produced by fermentation and oxidation of natural carbohydrates is called vinegar; a salt, ester, or acylal of acetic acid is called acetate.

 Industrially, acetic acid , is used in the preparation of metal acetates, used in some printing processes; vinyl acetate, employed in the production of plastics; plastic acetates used in making photographic films and textiles; and volatile organic esters (such as ethyl and butyl acetates), widely used as solvents for resins, paints, and lacquers. Biologically, acetic acid is an important metabolic intermediate, and it occurs naturally in body fluids and in plant juices.

Characteristics of Acetic Acid

1. Chemical and Physical Properties

  • Chemical Formula: CH₃COOH.
  • Molecular Weight: Approximately 60.05 g/mol.
  • Appearance: It is a colorless liquid with a strong, pungent odor.
  • Melting Point: 16.6°C (62°F), which means it can solidify at slightly lower temperatures.
  • Boiling Point: 118°C (244.4°F), allowing it to vaporize relatively easily under standard conditions.
  • Density: Approximately 1.049 g/cm³ at 20°C.
  • Solubility: Highly soluble in water due to its polar nature, allowing it to mix in all proportions with water. It is also soluble in alcohol and ether.

2. Acidity and pH

  • Weak Acid: Acetic acid is a weak acid, meaning it partially dissociates in water.
  • pKa: Approximately 4.76 at 25°C, indicating a moderate level of acidity compared to stronger acids like hydrochloric acid.
  • pH in Solution: When diluted, acetic acid has a pH between 2.4 and 3.4, making it acidic but relatively mild.

3. Odor and Taste

  • Distinct Odor: Acetic acid has a strong, pungent, and vinegar-like smell that is easily recognizable.
  • Taste: It has a sour taste when diluted, as it is the primary component responsible for the taste and smell of vinegar.

4. Chemical Behavior and Reactions

  • Reactivity with Bases: Acetic acid reacts with bases to form acetate salts, such as sodium acetate when reacting with sodium hydroxide.
  • Esterification: Acetic acid reacts with alcohols in the presence of an acid catalyst to form esters, a reaction widely used in the production of fragrances and solvents.
  • Oxidation: While stable under normal conditions, acetic acid can be oxidized by strong oxidizing agents, producing carbon dioxide and water.
  • Reduction: Acetic acid can be reduced to form aldehydes, such as acetaldehyde, under specific conditions.
  • Polymerization: It can polymerize when exposed to particular conditions, but this is uncommon and not a typical property of acetic acid.

5. Biological Role

  • Metabolic Pathways: Acetic acid plays a role in the Krebs (citric acid) cycle, as acetate is a fundamental building block in metabolism.
  • Natural Occurrence: It occurs naturally in body fluids, food, and fermentation products.

6. Applications and Uses

  • Food Industry: Commonly used as a preservative, flavoring agent, and acidity regulator in products like vinegar (5–8% acetic acid solution).
  • Chemical Industry: Used as a precursor for synthesizing chemicals like acetic anhydride, vinyl acetate, and esters.
  • Pharmaceuticals: Plays a role in the production of certain medications and can be used as an antiseptic in diluted form.
  • Textiles and Plastics: Used in the production of synthetic fibers, plastics, and as a dyeing agent.
  • Cleaning Agent: Effective in household and industrial cleaning due to its ability to dissolve grease and limescale.

7. Safety and Handling

  • Corrosive: Concentrated acetic acid is corrosive and can cause skin burns and irritation. Diluted solutions are generally safe for handling with proper precautions.
  • Flammability: Acetic acid is flammable in concentrated form, with a flashpoint of around 39°C (102°F). It should be handled away from open flames and stored properly.
  • Irritant: Inhalation of its vapors can cause respiratory irritation, and direct contact with skin or eyes can cause burns.

8. Environmental Impact

  • Biodegradable: Acetic acid is readily biodegradable and does not persist in the environment.
  • Environmental Hazard: While generally safe, spills of concentrated acetic acid can cause local environmental harm due to its acidity.
