| titleOfInvention | Obtaining caprolactam by cleavage of molten polycaprolactam |
| abstract | Caprolactam is obtained from caprolactam-containing polymers in the presence of a base under reduced pressure by depolymerizing polymers which contain the repeating unit-[-N(H)-(CH2)5-C(O)-]- or mixtures consisting essentially of from 50 to 99.99% by weight of a polymer containing the repeating unit -[-N(H)-(CH2)5-C(O)-]-, from 0.01 to 50% by weight of additives selected from the group consisting of inorganic fillers, organic and inorganic pigments and dyes, from 0 to 10% by weight of organic and/or inorganic additives, from 0 to 40% by weight of non-polyamide-containing polymers and from 0 to 20% by weight of polyamides, with the exception of polycaprolactam and copolyamides prepared from caprolactam, in at least two depolymerization reactors connected in series. |
