Isopropyl acetate, physical properties

Commonly used water-immiscible solvents in industrial-scale processes include alcohols (isobutanol, -butanol), ketones (particularly methyl isobutyl ketone), acetates (butyl, ethyl, isopropyl), hydrocarbons (toluene, hexanes), and methylene chloride. These solvents are inexpensive, readily available, and exhibit physical properties of low viscosity and density significantly different from water. Common water-miscible solvents are the alcohols (particularly methanol). For laboratory-scale processes, the selection is greater since selection is not constrained by economics. Craig and Sogn (16) have prepared an extensive compilation of such solvents. 

Illustration 1. Acetic acid is to be extracted from water by isopropyl ether in a tower packed with carbon Raschig rings, ether dispersed. Flow rates are to be 30 cu. ft./hr. ether, 45 cu. ft./hr. water. Average physical properties are aqueous phase density pc = 63.0 Ib./cu. ft., viscosity mc = 3.1 centipoises ether phase density pD = 45.6 Ib./cu. ft. interfacial tension [Pg.308]
