Application of the turbidimetric titration method to study the molecular-weight distribution of sulfite cellulose in acetylation

  • 35 Accesses

Conclusions

-- It is recommended to the central plant laboratories of man-made fibres to use the method of turbidimetric titration to determine the molecular-weight distribution of sulfite cellulose in the process of working it up.

-- A rapid method has been developed for determining a molecular-weight distribution of sulfite cellulose for acetylation using a selective solvent—precipitant system.
