Abstract
Provided is a method for producing a cellulose derivative. The method includes forming a first reaction product by reacting non-oxidized cellulose with at least one first alkalization agent in the presence of at least one suitable solvent, wherein the first reaction product includes a non-oxidized alkali-cellulose. The method further includes forming a second reaction product by reacting a monohalo-organic compound with a second alkalization agent in a solution, wherein the second reaction product includes a saturated solution and a sediment. The method further includes increasing a temperature of the saturated solution and dissolving at least a portion of the sediment, and reacting the non-oxidized alkali-cellulose with the second reaction product to form an improved carboxymethyl cellulose.
