NOVELTY – Carbonate activated polyalkylene oxide production involves reacting polyalkylene oxide with sodium hydride in presence of an organic solvent to obtain an alkoxide. The polyalkylene oxide and sodium hydride are reacted by using single reactor with constant agitation. The obtained alkoxide is reacted with an organic reagent in presence of co-solvent to obtain a reaction mixture. The obtained reaction mixture is filtrated to separate organic carbonate, and concentrated by evaporation of solvent. The organic carbonate is precipitated to obtain activated carbonate and polyalkylene oxide residue. USE – Method for producing carbonate activated polyalkylene oxide for use as organic macromolecule modifier for use in chemical and pharmaceutical industries (claimed), and for chemical modification of molecules having nucleophilic sites such as proteins, amino acids, peptides, polypeptide, nucleotides, nucleosides, polysaccharides, nitrogen bases, taxanes and their derivatives. ADVANTAGE – The carbonate activated polyalkylene oxide production is easy and produced carbonate activated polyalkylene oxide has low degree of toxicity, thus it is eco-friendly.
