Abstract
The invention relates to an onium salt, a liquid composition containing the onium salt and cellulose, and a method for recovering cellulose. The invention makes it possible to provide an onium salt having an extremely high ability to dissolve cellulose at temperatures of 100° C. or lower. It also makes it possible to provide a liquid composition containing this onium salt and cellulose, as a composition suitable for the recovery of cellulose, and a method for recovering cellulose efficiently by using such a liquid composition containing the onium salt and cellulose.
