What is Adipic Acid CAS 124-04-9?

CAS 124-04-9 is adipic acid, also called hexanedioic acid or 1,4-butanedicarboxylic acid, with the molecular formula C6H10O4. This product is a white crystalline dicarboxylic acid supplied in industrial or technical grade.

What are the typical physical properties of industrial-grade adipic acid?

It is normally a white crystalline powder or granule with a melting point near 151-155 degrees C. The solid has low solubility in cold water but dissolves more readily in hot water, and it can form combustible dust if finely dispersed.

How is Adipic Acid CAS 124-04-9 mainly used in industry?

The largest use is as a monomer for nylon 66, produced by polycondensation with hexamethylenediamine. It is also used to make polyester polyols for polyurethane elastomers, foams, coatings, and adhesives, as well as adipate ester plasticizers.

Can this adipic acid grade be used in polyurethane and plasticizer applications?

Yes. The technical/industrial grade is suitable as a raw material for polyester polyols and for adipate esters such as DOA and DIDA. For highly regulated end uses, confirm the applicable purity, moisture, and trace-metal specifications with your downstream process.

What handling precautions apply to adipic acid powder?

Avoid creating airborne dust and use local exhaust ventilation in powder-handling areas because combustible dust can form explosive mixtures. Standard chemical handling practice also includes eye, skin, and respiratory protection to reduce irritation risk.

Adipic Acid CAS 124-04-9

Adipic acid, identified by CAS 124-04-9, is a white crystalline dicarboxylic acid that serves as a fundamental building block within the Basic & Fine Chemicals sector for the global polymer and synthetics industries. This hexanedioic acid functions as a primary monomer in the polycondensation of polyamides, specifically driving the structural formation of high-tenacity fibers and engineering plastics. Beyond its role in polymer science, it acts as a pH regulator and acidulant in various industrial formulations, contributing to the synthesis of plasticizers such as Di-n-octyl Adipate, polyurethane resins, and specialized lubricants where long-chain stability is required. Dimethyl Adipate (DMA) is the corresponding dimethyl ester form where an ester feed is specified. We provide this material with competitive factory pricing to support large-scale manufacturing of industrial resins and textile precursors, ensuring that all batches meet customized specifications for purity and color stability. Our logistics infrastructure is optimized for bulk supply, and every shipment is accompanied by comprehensive technical documentation, including MSDS, TDS, COA, to ensure regulatory compliance and process safety.

Applications

Nylon Production: The critical precursor for the manufacture of Nylon 66 fibers and resins used in automotive parts and industrial textiles.
Polyurethanes: Utilized in the production of polyester polyols for flexible and rigid foams, as well as TPU elastomers.
Plasticizers: Serves as a raw material for adipate esters (such as DOA) which provide low-temperature flexibility in PVC applications.
Industrial Additives: Used in wet-strength resins for paper, as a buffering agent in flue gas desulfurization, and in the synthesis of specialized lubricants.

For polyester or polyamide routes using a shorter-chain dicarboxylic acid, Glutaric Acid is a separate industrial building block.

Storage & Safety

Storage: Store in a cool, dry, and well-ventilated area. Keep away from heat sources and strong oxidizing agents. Bags should be kept tightly sealed to prevent moisture absorption and caking.
Handling: Avoid dust formation during charging or discharging. Ensure adequate ventilation in the workspace to keep airborne concentrations below exposure limits.
PPE Recommendations: Wear safety glasses with side shields, chemical-resistant gloves (PVC or Nitrile), and a dust-filtering respirator (P2 or N95) when handling the powder in bulk.

Quality Assurance

Our production facility utilizes high-pressure nitric acid oxidation of cyclohexane derivatives to ensure a high-purity crystalline output. Each batch undergoes rigorous analysis, including gas chromatography for organic purity and atomic absorption spectroscopy for trace metal monitoring. We maintain strict control over the particle size distribution and moisture levels to guarantee free-flowing characteristics, providing the technical reliability required for continuous polymerization and large-scale industrial synthesis.
