Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania estru kwasu tereftalowego i alkoholu alifatycznego C8, z odpadowego poli(tereftalanu etyienu), który polega na tym, że mieszaninę odpadowego poli(tereftalanu etylenu) i alifatycznego alkoholu C8 poddaje się transestryfikacji wobec katalizatora z grupy obejmującej butylo tris(2-etyloheksanian) cyny, bis(2-etyloheksanian) cyny, tlenek monobutylocyny, tlenek dibutylocyny oraz tlenek dioktylocyny. Reakcja przebiega w reaktorze okresowym, w temperaturze od 120 do 280°C, w czasie od 1 do 10 godzin, pod ciśnieniem od 500 do 1000 mBar. Udział katalizatora wynosi od 0,1 do 10% m/m w odniesieniu do masy poli(tereftalanu etylenu), zaś stosunek masowy alkoholu do poli (tereftalanu etylenu) wynosi od 1,2:1 do 8:1. Glikol polietylenowy, który powstaje w reakcji jest w sposób ciągły usuwany ze środowiska reakcji przez destylację. Uzyskaną mieszaninę poreakcyjną przesącza się i przemywa się wodnym roztworem wodorotlenku sodu, potasu albo amonu, o stężeniu od 1 do 15% m/m, w ilości od 1 do 50% m/m, w odniesieniu do masy przesączonej mieszaniny poreakcyjnej i przemywa się wodą destylowaną. Z oczyszczonej mieszaniny poreakcyjnej oddestylowuje się nadmiar alkoholu i otrzymuje surowy produkt, który można bezpośrednio zastosować jako plastyfikator, albo wcześniej poddać dalszemu oczyszczeniu.
