Isononanoic Acid (CAS: 26896-18-4) Supplier in South Africa

Isononanoic acid, a monofunctional carboxylic acid with the chemical formula C9H18O2, is an important intermediate in industrial chemistry. Found both as a synthetic and natural product, it exhibits a clear, oily liquid form at room temperature and carries distinctive characteristics that make it valuable in various applications.

The acid serves as a critical component in the synthesis of alkyd resins, which are extensively utilized in the formulation of coatings for stoving enamels and two-component paints that require enhanced yellowing resistance.

In the realm of organic chemistry, isononanoic acid is known for its consistent high purity, which is essential for the production of specialized synthetic lubricants. These lubricants are pivotal in sectors demanding high performance and precision, such as refrigeration and aviation. Moreover, due to its branched-chain structure, this medium-chain fatty acid finds relevance in improving the properties of end products, positively impacting their stability and effectiveness.

As isononanoic acid continues to be studied and applied, its presence in naturally occurring species like Solanum pennellii underscores the versatility and ubiquity of this carboxylic acid in both natural and industrial domains. Its role in advancing material science and industrial processes exemplifies the synergy between nature-derived compounds and their engineered counterparts.

Chemical Properties

The chemical properties of Isononanoic Acid, a branched-chain saturated fatty acid, are characterized by its distinct molecular structure, physical state, solubility, alongside precise boiling and melting points.

Molecular Structure

Isononanoic Acid has a molecular formula of C9H18O2. Its structure includes a branched-chain, resulting from a 7-methyl group present in the compound, which distinguishes it from straight-chain fatty acids.

Physical State

At room temperature, Isononanoic Acid is typically found in liquid form. It displays clear to slightly yellowish appearance owing to its molecular composition.

Solubility

Isononanoic Acid is known for its moderate solubility in water, which varies depending on the temperature and pH. It is, however, readily soluble in organic solvents like ethanol, methanol, and ethers indicating its versatile nature.

Boiling and Melting Points

The boiling point of Isononanoic Acid is recorded at approximately 255°C (491°F), while its melting point is generally observed just below room temperature, around -54°C (-65.2°F), signifying a low freezing point relative to many other fatty acids.

Synthesis and Production

The production of isononanoic acid involves specialized chemical processes that convert specific starting materials into the desired acid through a series of reactions.

Industrial Preparation

In industry, isononanoic acid is mainly produced from 2-ethylhexanol. The process begins with the dehydration of 2-ethylhexanol to create octenes. These octenes undergo hydroformylation to form isononanal, which is then oxidized to yield isononanoic acid.

• Dehydration: 2-ethylhexanol → Octenes
• Hydroformylation: Octenes → Isononanal
• Oxidation: Isononanal → Isononanoic Acid

Health and Safety

The health and safety profile of Isononanoic acid is characterized by its toxicological effects, regulatory status, and specific handling and storage guidelines to ensure safety.

Handling and Storage

Safe handling of Isononanoic acid involves:

• Using personal protective equipment (PPE): Ensuring that skin and eye protection is worn to prevent irritation or damage.
• Avoiding ingestion: Due to its toxicity upon oral intake.

When storing Isononanoic acid, it is crucial to:

• Keep it in a well-ventilated area away from incompatible materials.
• Store at controlled room temperature to maintain its stability and integrity.

Compliance with safety data sheet (SDS) recommendations ensures that risks are minimized during interaction with the substance.
