On cellulose degradation in heterogeneous reactions

It has been shown theoretically that the quasiperiodical distribution of unordered regions along cellulose microfibrils does not significantly affect the molecular weight distribution which arises from heterogeneous reactions of cellulose involving a limited number of acts of chain rupture.

Description
Summary:It has been shown theoretically that the quasiperiodical distribution of unordered regions along cellulose microfibrils does not significantly affect the molecular weight distribution which arises from heterogeneous reactions of cellulose involving a limited number of acts of chain rupture. On a montré théoriquement que la distribution quasipériodique des régions désordonnées le long de microfifres de cellulose n'affecte pas de façon significative la distribution des masses moléculaires que l'on obtient à partir des réactions hétérogènes de la cellulose mettant en jeu un nombre limité de ruptures de chaine. E' stato dimostrato teoricamente che la distribuzione quasi periodica delle zone ordinate lungo le micronbrille cellulosiche non influenza in modo significativo la distribuzione del peso molecolare che si ha dalle reazioni eterogenee della cellulosa che implicano un numero limitato di azioni di rottura della catena. Es ist theoretisch gezeigt worden, dass die quasi periodische Verzweigung ungeordneter Regionen entlang Zellstoffäserchen die Molekulargewichtsverteilung unwesentlich beeinflusst, welche aus heterogenen Zellstoffreaktionen entsteht, die eine begrenzte Anzahl von Kettenbruch vorgängen mit sich bringen.
