ABSTRACT:
A method of treating cellulose-containing materials to increase chemical and biological reactivity of cellulose. The cellulose is contacted, in a pressure vessel, with a volatile liquid swelling agent having a vapor pressure greater than atmospheric at ambient temperatures, such as ammonia. The contact is maintained for a sufficient time to enable said agent to swell the cellulose fibers. The pressure is rapidly reduced to atmospheric, allowing said agent to boil and explode the cellulose fiber structure. The rapid pressure reduction also causes some freezing of the cellulose. The agent is separated from said cellulose and recovered for recycling.
