Method for manufacturing high-cationic starch solutions

A method for producing starch solutions of high cation equivalent value with a DS of 0.1-1.0) is provided. The starch to be cationized is slurried to form a suspension of about 10-80% solids content in an aqueous mixture of a cationizing agent. In the cationization chlorohydrin-functional cationizin...

description A method for producing starch solutions of high cation equivalent value with a DS of 0.1-1.0) is provided. The starch to be cationized is slurried to form a suspension of about 10-80% solids content in an aqueous mixture of a cationizing agent. In the cationization chlorohydrin-functional cationizing agent is used by about 90-1100 g per kg starch solids, and a catalyst is added to the slurry. The reaction is carried out at a high solids content of 40-80% in at least two steps, in the first of which a temperature of about 5-40° C. in maintained, and in the second step a temperature of about 70-180° C.
