Abstract

Sürekli bis (3-hidroksipropil) tereftalat ve moleküler agirligi düsük 1,3-propandiol ve tereftalik asit oligomerlerinden en az birini üretme islemi ortaya konulmaktadir. IslemE göre önceden isitilmis 1,3-propandiol (yaklasik 150 C ila yaklasik 200 C) ve önceden isitilmis tereftalik asidin alt dialkil esterleri (yaklasik 150 C ila yaklasik 220 C), yaklasik 1.2:1 ila yaklasik 2.3:1'lik bir mol oraninda birlestirilir ve bir ester degistirme teknesine beslenir; burada karisim, sürekli bir transesterlestirme reaksiyonuna girer. Sivi reaksiyon karisimi, yaklasik 215 C ila yaklasik 250 C arasindaki bir sicaklikta ve yaklasik 800 mm Hg ila yaklasik 1,000 mm Hg arasindaki bir basinçta sürekli olarak isitilir ve karistirilir.
