- Abstract
Sulfation of MCC by sulfamic acid in DMF or diglyme in the presence of urea was studied for the first time. It was established, that the degree of substitution in sulfated MCC was in the range from 1.40 to 1.54. It was shown, that the most effective sulfation of MCC takes place in diglyme. The yield of cellulose sulfate at sulfation MCC in diglyme was 2.5 times higher than the yield for sulfation MCC in N,N-dimethylformamide
