Abstract

Yüksek viskoziteli selüloz eterlerinin, hidrojen peroksit ile oksidatif olarak ayristirilmasiyla, düsük viskoziteli, suda çözünür selüloz eterlerinin üretilmesi için bir yöntem açiklanmistir. Yüksek viskoziteli selüloz eteri, 65-125 oC arasi sicakliklarda sulu bir hidrojen peroksit çözeltisiyle yogun bir sekilde karistirilir. Karistirma orani, hidrojen peroksit miktari, kuru selüloz eteriyle iliskili olarak agirlikça %0.1-10 arasi olacak; karisimin kati muhtevasi, karisimin toplam miktariyla iliskili olarak agirlikça %25'ten az olmayacak ve karisim, hidrojen peroksidin en azindan yaklasik olarak %90'i kullanilana degin, 65-125 oC arasi sicakliklarda hareket halinde tutulacak sekilde seçilir.
