Abstract:Polietilen tereftalat v tekstilni industriji poznamo tudi pod imenom poliester. Količina odpadnega poliestrnega tekstilnega materiala narašča, zato je potrebno poiskati primerne načine za njegovo recikliranje in ponovno uporabo. Kot uspešni postopki kemijske razgradnje so se izkazal različni postopki hidrolize. Diplomsko delo je namenjeno analizi razgradnih produktov poliestrnih tekstilnih materialov po alkalni in nevtralni hidrolizi ter čiščenju nastalega trdega produkta. Čiščenje smo izvedli s postopki kristalizacije, sublimacije, vroče filtracije in kislinsko bazne ekstrakcije. Rezultati so bili ovrednoteni s pomočjo IR spektroskopije in potenciometričnih titracij v nevodnem mediju. Ugotovili smo, da se nobeden od postopkov čiščenja ni izkazal za zelo uspešnega, v neki meri sta učinkovita le postopka kristalizacije in sublimacije.

Title:Isolation and purification of terephthalic acid from polyester textile materials
Abstract:Polyethylene terephthalate in the textile industry is also known as polyester. The amount of waste polyester textile material is increasing, so it is necessary to find suitable ways for its recycling and reuse. Various hydrolysis procedures have been proven as successful methods of chemical degradation. The diploma work presented analysis of degradation products of polyester textile materials after alkaline and neutral hydrolysis and purification of the resulting solid product. The purification was carried out by crystallization, sublimation, hot filtration and acid base extraction processes. The results were evaluated by IR spectroscopy and potentiometric titrations in a non-aqueous medium. We found that none of the purification processes proved to be very successful, to some extent only the crystallization and sublimation processes are effective.
Keywords:polyester, neutral hydrolysis, alkaline hydrolysis, terephthalic acid, purification, textile materials, waste
