ZUSAMMENFASSUNG:Aus HeiBwasserextrakt von Polycaprolactam wurden durch Kurzwegdestillation im Hochvakuum cyclisches Tetrameres und aus dem Ruckstkd cyclisches Pentameres des Caprolactam isoliert. Die Synthese des cyclischen Trimeren gelang nach der Azidmethode. Aus dem cyclischen Dimeren wurde mit Dimethylsulfat das monomethyl-schwefelsaure Salz eines Imidoesters gewonnen.
SUMMARY:The cyclic tetramer of caprolactam has been isolated from a hot water extract of the polymer by high vacuum distillation and the pentamer by recrystallization of the residue. The synthesis of the cyclic trimer has been accomplished by the azide method. By heating the cyclic dimer with dimethyl sulphate the monomethyl sulphate of the iminoester was prepared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
