Hydrocarbon Azeotropes with Acetonitrile

High Temperature Distillation.

“…Denyer et al (26) report azeotropes formed between thiols and paraffins or naphthenes. Azeotropes between acetonitrile and paraffins, olefins, naphthenes, and benzene or toluene are reported by Bishop et al (6). Equilibrium constant charts for light hydrocarbons are presented by Smith and Smith (99).…”

“…Steam ejection, single and multiple effect, heat pump cycles employing ammonia compressors (SO) and combinations thereof have performed the transfer of water from juice to condensate. In addition to orange, lemon, pineapple, grape, and apple juices (5-7, 12, 49) an important newcomer is a soluble coffee (5,6,11,19,43,45), which is being produced at a water-vapor pressure of about 1 mm. and a residual air atmosphere of less than 30 microns.…”

Tuning enantioselectivity for crystallization-induced asymmetric synthesis of a conglomerating oxo-rhenium(v) complex

“…mL solvents .b Initially added seeds of C-(+)-cis-1 (ee = +99.5%)8 expressed as a mole fraction of whole rhenium substrate compounds, x (+)Re %. c Except for experiment 2, the boiling temperature of the neat solvent or the azeotrope9 was used. d Yield after subtraction of the amount of the initially added seeds.…”
