ABSTRACT:
An improved process for the production of alkylene glycol alginates from seaweeds of the Class Phaeophyceae by treating with a dilute aqueous solution of a strong acid, washing the solid residue, optionally but preferably neutralizing only part of the free alginic acid in the washed residue with an alkaline agent, esterifying the unisolated alginic acid in situ in the solid seaweed residue with an alkylene oxide, and recovering the alkylene glycol alginate so formed from the resulting reaction mixture.
