Correlation of the distribution curve with the dispersion curve of cellulose nitrate

Wilson, Clifton HerbertVirginia Tech1960

… acceptable with ±10% of the values obtained from fractional precipitation. Thus the distribution curve of cellulose nitrate may be determined from the dielectric dispersion curve.

Dielectric dispersion of ethyl cellulose solutions

Hawkins, Miller CampbellVirginia Polytechnic Institute1959

… celluloee fractions were refractionated by a fractional precipitation procedure in order to obtain fractions that were homogeneous with respect to chain length. Ethyl acetate and acetone were used in the ratio of three to one (3:1) as solvents, and water acetone in the ratio of ninety-five to …

The fractionation of dextran using ethanol

Bhambra, Kalwant S.Aston University1985

… chromatography theories have been made. Fractional precipitation with ethanol has to be performec at least twice to obtain clinical dextran, which is a poly­glucose, from an aqueous solution of dextran having a broad molecular weight distribution. In the first stage the high molecular …
