I plan to post to the files area two proposals from, of all agencies, NASA, that could be of interest to the group, but here are excerpts.
LAR-14895: "In one version of this process,castor oil would be added to an ethanol/water solution.The ethanol would mix freely with castor oil,which is insoluble in water.The resulting ethanol/castor-oil phase,which would contain less than 1 percent water,would collect as the top layer,the bottom layer being the remainder of the ethanol/water solution somewhat depleted in ethanol.Heating this two-layer mixture to a temperature slightly below the boiling temperature of ethanol (78.5 ¡C)would cause the partial pressure of ethanol above the top layer to be much greater than the partial pressure of either castor oil or water.This vapor-phase ethanol could be condensed in a relatively pure state." LAR-14894: "In one version of this concept,sulfur would be added to an ethanol/water mixture:a slight amount of sulfur that depends on the temperature of the mixture would be dissolved by the ethanol.(All three forms of sulfur are insoluble in water,even at its boiling temperature,but the a form of sulfur is slightly soluble in ethanol and the b form is more soluble in ethanol,according to the CRC Handbook of Chemistry and Physics.)The sulfur/ethanol mixture would settle to the bottom of the container,where it could be bled off.This small part of the original mixture could then be heated to separate the volatile ethanol from the significantly less volatile sulfur.The hot sulfur left after the distillation could be added to another batch of the ethanol/water mixture."
