Abstract
Μέθοδος μετατροπής - ανακύκλωσης πολυμερικών απόβλητων υλικών παρουσία δότη - οξυγόνου, χημικής βάσης, μεταφορέα φάσης και καταλύτη (μεταλλοπορφυρινικό σύμπλοκο), ή άλλης χημικής ένωσης που μπορεί να μεταφέρει οξυγόνο με τελικό προϊόν πολυεποξείδια, πολυαιθέρες και πολυαλκοόλες. Η διαδικασία αυτή αναφέρεται σε μια πολυμερική ουσία είτε σε μίγμα πολυμερικών ουσιών που μας ενδιαφέρει και μπορούν να μετατραπούν - επανακυκλωθούν με τον τρόπο αυτό. Η μέθοδος χαρακτηρίζεται από την δυνατότητα ελέγχου της μετατροπής με την πάροδο του χρόνου είτε ως προς το υπόστρωμα (πολυμερές) είτε προς τον καταλύτη. Οι πολυαλκοόλες διαχωρίζονται από τους πολυαιθέρες και τα άλλα πολυμερή του μίγματος της αντίδρασης με την καταβύθησή τους σε διάλυμα χλωροφορμίου με βενζόλιο. Το βενζόλιο είναι η αιτία της παραπάνω καταβύθησης. Θα μπορούσε επίσης εύκολα η παραπάνω μέθοδος να χρησιμοποιηθεί επίσης και για την παραγωγή νέων εύχρηστων πολυμερών (πολυεποξείδια, πολυαιθέρες ή πολυαλκοόλες) και αλκοολών, οξέων, κετονών, αλδεϋδών από προϋπάρχοντα (πολυενικά πολυμερή). ωMethod of conversion - recycling of polymeric waste materials in the presence of a donor - oxygen, chemical base, phase transporter and catalyst (metalporphyrin complex), or other chemical compound that can transport oxygen with end product polyepoxides, polyethers and polyalcohols. This process refers to a polymeric substance or a mixture of polymeric substances that we are interested in and can be converted - recycled in this way. The method is characterized by the possibility of controlling the conversion over time either with respect to the substrate (polymer) or with respect to the catalyst. The polyalcohols are separated from the polyethers and other polymers in the reaction mixture by immersing them in a benzene chloroform solution. Benzene is the cause of the above precipitation. The above method could also easily be used for the production of new easy-to-use polymers (polyepoxides, polyethers or polyalcohols) and alcohols, acids, ketones, aldehydes from pre-existing ones (polyene polymers). oh
