The present invention relates to a method of processing cellulosic materials, particularly to a method of dissolving cellulose from cellulose containing feedstock, such as pulp, by contacting the cellulose containing feedstock with thermally and chemically stable ammonium salts, such as spirocyclic ammonium salts or quaternised cyclic ammonium salts. The invention also relates to the use of said ammonium salts for cellulose processing and to a method of manufacturing cellulose- based shaped articles.
