Claims (10)

1. Förfarande för framställning av cellulosakarbamat av cellulosa och urea, kännetecknat därav, att den banformiga cellulosan utsätts för en strälningsdos av storleksordningen 0,5-10 Mrad frän en stralningskälla, varefter cellulosan bringas att reagera med urea i för- 5 höjd temperatur.
2. Förfarande enligt patentkravet 1, kännetecknat därav, att cellulosan efter besträlningen behandlas i banform med flytande anmoniak i vilken har upplösts urea, anmoniaken avdunstas och cellu- 10 losan upphettas för att bringa den att reagera med urean för bildande av cellulosakarbamat.
3. Förfarande enligt patentkravet 1, kännetecknat därav, att cellulosan efter besträlningen behandlas med flytande anmoniak i 15 vilken har upplösts urea, anmoniaken avdunstas och cellulosan upphettas i ett flytande medium i vilket urean är väsentligen olöslig.
4. Förfarande enligt patentkravet 3, kännetecknat därav, att som flytande medium används ett aromatiskt eller aromatfritt kol- 20 väte eller en kolväteblandning.
5. Förfarande enligt patentkravet 2,3 eller 4, kännetecknat därav, att behandlingen av cellulosan med ureaanmoniaklösningen sker i en temperatur under -33° eller i ett tryckkärl i en temperatur högre 25 än ammoniakens kokpunkt.
6. Förfarande enligt nägot av patentkraven 1-5, kännetecknat därav, att reaktionen mellan cellulosa och urea genomförs i sänkt tryck. 30
7. Förfarande enligt nägot av patentkraven 1-6, kännetecknat därav, att reaktionsprodukten efter reaktionen mellan cellulosa och urea tvättas med flytande anmoniak. 1 Förfarande enligt nägot av patentkraven 1-7, kännetecknat
