ABSTRACT:
The invention relates to a process for the preparation of low-viscosity cellulose ethers, in particular of methylcelluloses having viscosities of less than 100 mPa.s, measured in 1.8% aqueous solution. The process is carried out in such a way that an aqueous sodium chlorite solution is added preferably during and/or after alkalization, but before etherification.
