Therefore, we have investigated conditions of esterification of cellulose in water solutions of carbamide mixed with polyphosphoric acids.
2]Cl) of groups free from phosphorylation with further interaction with potassium iodide showed that the process proceeds in primary alcoholic groups (13); the degree of substitution of hydroxyl groups on the residues of polyphosphoric acids reaches 0.
Thus, the reaction of esterification of cellulose by condensed polyphosphoric acids produces the derivatives of cellulose and pyro- and tripolyphosphoric acids:
