The Viscosity of cottonseed oil, fractionation solvents and their solutions

Journal of the American Oil Chemists' Society, 1991
Cold fractionation of cottonseed oil is made difficult by the high viscosity of the oil. This study was aimed at demonstrating the effect of solvents on the viscosity of mixtures between 0°C and 25°C with a view to facilitating the fractionation of refined cottonseed oil.

Fractionation of five technical lignins by selective extraction in green solvents and characterisation of isolated fractions

Industrial Crops and Products, 2014
Lignins from softwood, hardwood, grass and wheat straw were fractionated by selective extraction at ambient temperature using green solvents like acetone/water solutions of 10, 30, 50, 70 and 90% (v/v) acetone and ethyl acetate. A comparison between the isolated fractions and unfractionated lignins was made in terms of extraction yield, lignin ...

Selection of the solvent-precipitant system for the fractionation of copolymers

European Polymer Journal, 1970
Abstract A suitable system of solvent and nonsolvent for copolymer fractionation can be selected by determining the solubilities of parent homopolymers by the method of cloud-point titration. The method was verified on the graft polymer poly(propylene-g-styrene). As a system sensitive mainly to the mol. wt.
