Adipic acid, hexanedioic acid, is an organic compound with the formula (CH2)4(COOH)2. It is synthesized by oxidizing a mixture of cyclohexanone and cyclohexanol, commonly referred to as KA oil (ketone-alcohol oil). During the initial stages of the reaction, cyclohexanol transforms into ketone, releasing nitrous acid. Naturally occurring adipic acid is also found in beet juice as a dibasic carboxylic acid. It plays a crucial role in producing plasticizers, lubricant components, and polyester polyols for polyurethane systems. Additionally, its derivatives are widely utilized in the food industry for gelling, acidification, flavoring, leavening, and buffering applications and in manufacturing pesticides, dyes, textile treatment agents, fungicides, and pharmaceuticals.
The global adipic acid market is growing due to rising demand for nylon 6,6, which is extensively used in automotive, textile, and industrial applications. The increasing production of automobiles and the shift toward lightweight materials to enhance fuel efficiency are major driving forces. Adipic acid also has a significant presence in the polyurethane and coatings sectors, further boosting market growth. Stricter environmental regulations and sustainability efforts are fostering research into greener production methods, such as microbial fermentation and renewable feedstocks. Additionally, sustainable production advancements, market expansion in developing economies, and increasing applications in high-performance polymers are fueling growth. Innovations in bio-based alternatives and circular economy practices, such as recycling nylon waste, are expected to contribute to long-term market expansion.
The increasing demand for nylon 6,6 in the automotive industry is a key factor driving the market. The widespread adoption of lightweight materials in vehicle production to enhance fuel efficiency and comply with stringent carbon emission standards has amplified the need for high-performance engineering plastics like nylon 6,6.
Furthermore, environmental agencies like the U.S. Environmental Protection Agency (EPA) and the European Commission have mandated a 30% reduction in CO₂ emissions for new passenger vehicles by 2030. This regulation has prompted automakers to integrate lighter and more durable materials, such as nylon 6,6, into their designs. Additionally, increasing investments in electric vehicles (EVs) and adopting high-performance polyamide composites further reinforce adipic acid’s role in next-generation mobility solutions.
The rising emphasis on sustainability and circular economy initiatives presents a significant opportunity for bio-based adipic acid production. With renewable feedstocks offering a sustainable alternative to petroleum-derived adipic acid, companies are expanding bio-based manufacturing to align with evolving consumer and regulatory demands. The European Union’s Green Deal has set a 55% reduction target for industrial carbon emissions by 2030, pushing manufacturers toward bio-based and recycled chemical solutions.
RadiciGroup has launched bio-based adipic acid projects targeting European and North American markets, using sugar-based fermentation processes to reduce CO₂ emissions by 70% compared to traditional methods.
Furthermore, in 2024, Sumitomo Chemical partnered with leading research institutions to develop an enzymatic conversion process for adipic acid, reducing dependency on fossil fuel feedstocks. This transition to bio-based alternatives places adipic acid manufacturers at the forefront of green chemistry innovation, unlocking new revenue opportunities in the sustainable polymer industry.
The Asia-Pacific region remains the largest market for adipic acid, driven by expanding industrial production in China and India. China continues to dominate adipic acid production and consumption, supported by government initiatives to strengthen domestic chemical manufacturing.
Meanwhile, India’s adipic acid market is expanding due to rapid industrialization, with Reliance Industries investing in new production facilities. The region’s growing demand for textiles, automotive components, and consumer goods continues to drive market expansion, solidifying Asia-Pacific's role as a key growth hub for adipic acid.
