This application is effective in terms of energy consumption and time needed for the reaction. The reaction was carried out in a high pressure polytetrafluoroethylene reaactors in the presence of concentrated phosphoric acid as an acidic catalyst. Microwave irradiation power (200 W) and irradiation time (20 min) were kept constant, while the amount of phosphoric acid was varied. The existence of degraded products was confirmed by chromatographic methodsV tem delu je opisan postopek depolimerizacije PA-6, kjer smo kot vir termične energije uporabili mikrovalove. S tem smo zmanjšali porabo energije in skrajšali reakcijski čas. Reakcija je potekala v visokotlačnih politetrafluoroetilenskih reaktorjih v prisotnosti koncentrirane fosforne kisline kot kislinskega katalizatorja. Moč mikrovalovnega valovanja je bila konstantna (200 W), prav tako čas obsevanja (20 minut), količino kisline pa smo spreminjali. Nastanek degradacijskih produktov smo potrdili s kromatografskimi metodamiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
