ABSTRACT:
A process for producing a corn milling residue carboxymethyl ether salt comprises reacting a corn milling residue with alkali in the presence of an aqueous carboxymethylating agent solution to give a corn milling residue carboxymethyl ether salt with an average degree of substitution not less than 0.2. As the reaction medium, water alone is used in a proportion of at least 7 moles per mole of the corn milling residue. Carboxymethylation of the corn milling residue is accomplished evenly and smoothly.
