- Solubility: Highly soluble in alcohol and acetone; only slightly soluble in water
Primary Industrial Applications
As a leading chemical distributor, we supply premium-grade Adipic Acid tailored for multiple commercial sectors:
-
- Polymer & Plastics Production: Approximately 75% of global supply is reacted with hexamethylenediamine to synthesize high-strength Nylon 6,6. It is also a fundamental building block in manufacturing specialized polyurethanes, flexible plasticisers, and synthetic coatings.
- Food Industry Additive (E355): Utilised as a highly controlled acidity regulator and acidulant. It adds a reliable, tart flavor profile to commercial gelatin desserts, powdered drink mixes, jams, and jellies.
- Advanced Formulations: Acts as a performance additive in industrial lubricants, specialized surface coatings, and textile treatment auxiliaries.
Synthesis & Production Methods
We monitor global chemical manufacturing trends to ensure stable supply chains utilizing both conventional and emerging technologies:
-
- Conventional Industrial Synthesis: Traditionally produced via the nitric acid oxidation of a cyclohexanol-cyclohexanone mixture (commonly referred to as KA oil). While highly efficient, modern chemical plants focus on mitigating the nitrous oxide (\(\text{N}_2\text{O}\)) greenhouse gas emissions associated with this petrochemically rooted process.
- Green Bio-Based Synthesis: To meet modern corporate sustainability goals, emerging green methods utilize glucose as a renewable feedstock. Genetically engineered E. coli bacteria ferment glucose into cis,cis-muconic acid, which is subsequently hydrogenated into clean, sustainable adipic acid.
Safety, Handling, & Hazard Information
When sourcing from Brand Chemical & Supplies, ensuring secure site operations is our top priority. Review the summary safety data sheet (SDS) guidelines below:
- Respiratory Hazards: Inhalation of airborne dust causes severe respiratory tract irritation, resulting in coughing and sneezing. Appropriate PPE and dust extraction systems must be used.
- Eye & Skin Contact: Direct exposure poses a severe risk of serious eye damage and irritation.
- Combustibility & Storage: Classified as a combustible solid. Finely dispersed airborne dust particles can form explosive mixtures with air at high temperatures. Store away from open flames, intense heat, and incompatible oxidizing agents
