Abstract

An improved reactor (and process using the same) comprising multistage stirrer elements and baffles, which has particular dimensional ratios between the reactor diameter, the width and spacing of the stirrer elements, and the baffles. The reactor is particularly adapted for the production of polysaccharide ethers, especially cellulose ethers.
