Abstract

Burada metaksilenden izoftalik asit yapmak ve özellikle, bu veya baska sekilde üretilmis ham izoftalik asidi (IFA), ayrica baska safsizliklar ihtiva eden bir sivi dispersiyondan saflandirmak için bir yöntem açiklanmistir. Yöntemin saflandirma bölümü: (1) dispersiyonun, bir ham IFA filtre pastasi olusturmak üzere süzülmesini; (2) filtre pastasinin, bir çözelti olusturmak üzere yüksek sicaklikta, bir kristallendirme çözgeni içinde çözülmesini; (3) saflandirilmis IFA nin, çözeltinin sicakligini veya basincini veya herikisini düsürmek suretiyle kristallendirilmesini; (4) saflandirilmis IFA kristallerinin çözeltiden ayrilmasini; ve (5) yikanmis saflandirilmis IFA pastasinin, son kristallendirme çözgeni kalintilarini uzaklastirmak ve arzu edilir tanecik boyu ve biçimi elde etmek üzere, yüksek sicaklikta yeniden çözülmesi veya islatilmasini içerir. Seçimli kristallendirme çözgeni tercihan N-metil pirrolidondur.
