The Alsachimie site in Chalampé, Alsace, France, is a major European hub for the production of polyamide 6.6 (nylon) intermediates. The facility operates 24/7, employs over 650 people, and is classified as a Seveso high-threshold site due to the scale and nature of its chemical operations. The site has certifications ISO 9001 (Quality), ISO 14001 (Environment) and ISO 50001 (Energy).

Main Processes and Technologies

Continuous Production: The site runs non-stop throughout the year to ensure reliable supply to customers in automotive, textiles, electronics, and consumer goods sectors.
Integrated Platform: Alsachimie manages the WEurope industrial platform, providing utilities and services to other companies on-site, including Butachimie, Linde, and Air Products.
Advanced Chemical Processes: The site utilizes state-of-the-art technologies for the synthesis of key polyamide intermediates, with a focus on process safety, environmental management (ISO 14001), and energy efficiency (ISO 50001).
Energy and Utilities: The site features a modern energy production center, including a natural gas and waste-fueled power plant, supplying high and low-pressure steam to production units.

Products

Product	Description/Use
Nylon Salt (AH Salt)	Precursor for polyamide 6.6 polymerization
Adipic Acid	Key intermediate for nylon 6.6, leader in Europe
Hexamethylenediamine (HMD)	Essential for nylon 6.6 and coatings
KA-oil (Cyclohexanone/ Cyclohexanol mix)	Intermediate for adipic acid production
Olone	Intermediate in polyamide chain
Nitric Acid	Used in oxidation processes
Co-products (Di-acids, AGS)	By-products for other chemical markets

These products are used in high-performance plastics, technical fibers, and specialty coatings.

Hexamethylenediamine (HMD): 260,000 metric tonnes per year production capacity (as of 2025, following the startup of a new world-scale plant).
Adipic Acid: Alsachimie is a leading European producer, with capacity in the hundreds of thousands of tonnes per year (exact figure not publicly disclosed, but the site is described as a European leader).
Nylon Salt (AH Salt): Produced in large volumes to supply BASF’s and external polymerization plants

Feedstocks

Cyclohexane: Main raw material for KA-oil and adipic acid production.
Ammonia: Used in the synthesis of hexamethylenediamine (HMD).
Adiponitrile (ADN): Key feedstock for HMD and nylon salt production, supplied by the adjacent Butachimie plant.
Nitric Acid: Both a product and a process reagent.

The site benefits from close integration with Butachimie for ADN supply and with utility providers for energy and gases.
