This report presents the economics of Caprolactam production from cyclohexane located in the United States. Initially, cyclohexane is oxidized to a cyclohexanol/cyclohexanone. Then, the cyclohexanol is hydrogenated to cyclohexanone, which is submitted to an oximation reaction with hydroxylamine. Finally, the cyclohexanone oxime produced is converted to Caprolactam by Beckmann rearrangement.
This report concerns the production of Caprolactam from cyclohexane in the United States. This report reviews a cyclohexane photonitrozation process (PNC). Initially, cyclohexane is submitted to PNC with nitrosyl chloride. The oxime produced is then subjected to Beckmann rearrangement and Caprolactam is formed.
This report presents the economics of Caprolactam production from benzene located in the United States. Initially, benzene is hydrogenated to cyclohexane, which is oxidized to cyclohexanone. Then, the cyclohexanone undergoes an oximation reaction with hydroxylamine. Finally, the oxime produced is rearranged to Caprolactam.
This feasibility study shows the economics of a Caprolactam production process from butadiene and hydrogen cyanide based on an industrial plant located in the United States. Hexamethylenediamine (HMDA) is generated as by-product in the process under analysis.
This report presents the cost associated with a plant located in the United States producing Caprolactam from butadiene, carbon monoxide, hydrogen, and ammonia. The process under analysis involves the following steps: reaction of carbon monoxide with butadiene; hydrocarbonylation; amination and cyclization.
This report presents the economics of Caprolactam production from cyclohexanone in a plant located in the United States. In the process examined, the cyclohexanone feed undergoes an oximation reaction with hydroxilamine. The oxime produced is rearranged to Caprolactam.
This feasibility study examines the economics of a process producing Caprolactam from phenol located in the United States. Initially, phenol is hydrogenated to form cyclohexanone. The cyclohexanone is then submitted to an oximation reaction with hydroxylamine. Finally, the cyclohexanone oxime produced is converted to caprolactam by Beckmann rearrangement.
This study reviews the economics of a process for Caprolactam production from toluene. Initially, toluene is oxidized to benzoic acid, which is then hydrogenated to hexahydrobenzoic acid. The hexahydrobenzoic acid is reacted with nitrosyl sulfuric acid and oleum for caprolactam production. The economic analysis performed is based on a plant constructed in the United States.
