Located 12 miles north of Pensacola, on the Escambia River near the town of Gonzalez, is a major petrochemical production site, operated by several companies. The principle product is nylon 6,6, as fiber used for carpets and clothing, and in polymer chip form for automotive and electronic industries. Also produced here is adiptic acid, which is used in foods, such as Jell-o, and maleic anhydride. The company Solutia has been involved at the site for years, a division of Monsanto, now called Ascend Performance Materials. Also on site is ExxonMobil Chemical's Pensacola Specialty Elastomers Plant, which makes thermoplastic rubber, and Huntsman's Pensacola Site, involved in nylon chemistry. The complex was first developed by Monsanto in 1953, and covers more than 2,000 acres.
