Modelling and experimental study of separators for co-solvent recovery in a supercritical extraction process [PDF]
Co-solvent recovery in supercritical extraction is addressed here through a theoretical description of the behaviour of a CO2 + co-solvent mixture into a cascade of cyclonic separators, such as those existing in conventional fractionation processes based

Solvent Extractive Fractionation of Ziegler Polystyrene [PDF]
Abstract The solvent extractive fractional ability has been described, using Ziegler polystyrene as sample. The order in hot extraction is tetra-hydrofuran >dioxane >ethyl methyl ketone ≥ ethyl acetate, while that in cold extraction is benzene >> ethyl methyl ketone≥ethyl acetate=toluene.

Theoretically predicting the solubility of polydisperse polymers using Flory–Huggins theory
Polydispersity affects physical properties of polymeric materials, such as solubility in solvents. Most biobased, synthetic, recycled, mixed, copolymerized, and self-assembled polymers vary in size and chemical structure.

An improved method for the high isotacticity measurement of polybutene-1
High isotactic polybutene-1 (HiPB) plays important roles in presenting outstanding resistance to creep and crack at high temperature. Therefore, rapid and accurate measurement of the HiPB is extremely important for both synthesis and application of ...
