己内酰胺 | caprolactam | 105-60-2 | C6H11NO | 113.159 |
A kinetic investigation is offered of the hydrolysis in 7.72 N aqueous hydrochlorie acid at 110°C. of the cyclic di‐, tri‐ und tetraamides of ε‐caprolactam and of the cyclic diamide from hexamethylene diamine and adipic acid. The intermediates of the reaction, identified by chromatography, provide definite proof of the constitution of these cyclic compounds.
For the remarkable difference between the rate constants of the two isomeric cyclic diamides no simple explanation could be given on known structural grounds.
