Caprolactam Plants for Sale

Caprolactam (capro) is mainly used to make nylon 6 fibres and engineering plastics, which account for about 68% and 32% of global demand, respectively. Nylon 6 fibres are used extensively in textiles, carpets and industrial yarns, with tyre-cord a large and growing market, especially in China. Nylon resins are the basis of engineering plastics, used in electronic and electrical components and automobiles, and oriented polyamide films used widely in food packaging. Most capro is produced from cyclohexane (CX), but it can also be made from phenol or toluene. CX is oxidised to cyclohexane, then reacted with hydroxylamine sulphate to cyclohexanone oxime, followed by a Beckman rearrangement to yield capro. But this route also produces large volumes of ammonium sulphate (AS) and work is focused on reducing or eliminating the AS co-product.
