Abstract
Tarif edilen, selüloz türevlerini elde etmeye yarayan bir yöntemdir.Bu yöntem uygulanirken, selüloz bir alkali çözeltisi ile doyurularak suya dayanikli hale getirilir, doymus selüloz tercihe göre ezilir ve selüloz bir ornatma (sübstitüsyon) veya ekleme reaksiyonuna tabi tutulur.Bu esnada ornatma derecesi DS olan bir selüloz türevi elde edilir.Isleme tabi tutulan selüloz,amonyak ile aktif hale geçirilmis bir selülozdur.Selülozdaki alkalinin AHG'ye (anhidro glikoz veya susuz gilikoz birimine) olan molar orani , ornatma ve ekleme reaksiyonu baslangicinda arzulanan DS'in iki katini geçmez.Selülozun sismesi için, alkali selüloza dönüsmeyecek ve sadece selüloza serbest bir bilesen olarak yapisacak asiri miktarda alkaliye ihtiyaç yoktur.Ornatma ve ekleme reaksiyonunda kullanilan reaktif miktari daha azdir.Daha az yan ürün elde edilir.
