Process to prepare ε-caprolactam from 6-aminocaproic acid |
| abstract |
Process to prepare ε-caprolactam starting from a liquid aqueous mixture containing an alcohol and 6-aminocaproic acid by cyclization of 6-aminocaproic acid in the aqueous mixture at an elevated temperature. The alcohol is separated from the starting aqueous mixture before performing the cyclization to such extent that the concentration of alcohol in the aqueous mixture during the cyclization is less than 1 wt. %. The advantages include reduced amounts of undesirable by-product. |
