| titleOfInvention | Method of Obtaining Caprolactam by Hydrolytic Splitting of Molten Polycaprolactam |
| abstract | - [- N (H) - (CH 2 ) 5 -C (O) -] -,n n n From 40 to 99.99% by weight of a polymer having repeating units of - [- N (H) - (CH 2 ) 5 -C (O) -] -,n n n 0.01 to 50% by weight of an additive selected from the group consisting of inorganic fillers, organic and inorganic pigments and dyes,n n n From 0 to 10% by weight of organic or inorganic additives,n n n 0 to 40% by weight of a polymer which does not comprise polyamide, andn n n From 0 to 60% by weight of polyamide except copolyamide prepared from polycaprolactam and caprolactam,n n n (- [- N (H) - (CH 2 ) 5 -C (O) -] - at a reaction temperature of 280 to 320 ° C. and 7.5 to 15 MPa for a reaction time of less than 3 hours Is in the range of from 5: 1 to 13: 1, with the proviso that the reaction mixture consisting essentially of the water and the polymer used or the mixture used does not contain a gaseous phase under hydrolysis conditions Caprolactam is obtained from the caprolactam-containing polymer in the presence of phosphorus, in the presence of superheated water. |
