Abstract: [eng] [cze]
Chemical PET recycling to therephtalic acid and ethylenglycol is carried out through alkaline hydrolysis and subsequend electrodialysis. The alkaline glykol solution is recur to the hydrolysis. Crystallic therephtalic acid is separated from suspense and is washed and dried. Vakuum destilation is applied to get ethylenglycol. Chemická recyklace PET na kyselinu tereftalovou a etylenglykol se provádí basickou hydrolýzou a následnou elektrodialýzou. Basický roztok glykolu se vrací do hydrolýzy. Krystalická kyselina tereftalová se oddělí ze suspenze a po promytí se suší. Etylenglykol se získává vakuovou destilací.
