Water methyl ethyl ketone

A one-step LPO of cyclohexane directly to adipic acid (qv) has received a lot of attention (233—238) but has not been implemented on a large scale. The various versions of this process use a high concentration cobalt catalyst in acetic acid solvent and a promoter (acetaldehyde, methyl ethyl ketone, water).

An even more advantageous condition exists in the case of the toluene range hydrocarbons when methyl ethyl ketone and water are added. A ternary azeotrope of methyl ethyl ketone-water-nonaromatic hydrocarbons distills below 176° F. Neither methyl ethyl ketone nor methyl ethyl ketone-water forms an azeotrope with toluene hence, toluene will not distill until a temperature of 231 ° F. is reached, unless excess water is present. Thus, it is relatively easy to produce pure toluene from petroleum fractions ...

Van Wijk (VI) and Van Wijk, Vos, and Van Stralen (V3) pointed out that the temperature difference between a superheated binary liquid mixture and the dew point of the vapor bubbles which are formed shows a minimum at a certain low concentration of the more volatile component, and suggested that the bubble growth rate would also be least at this point. In the case of methyl ethyl ketone-water mixtures the minimum occurred at 4.1 wt. % ketone, which coincided with the experimentally observed maximum heat fiux.

TLC has been useful in the analysis of polyethylene oxide compounds. Compounds containing a small, medium or large number of ethylene oxide units are formed, depending on the amount introduced in the reaction. Burgeb [10] has determined the ethylene oxide content and molecular weight distribution of polyethylene oxide condensates with fatty acids, fatty alcohols and alkylphenols, using silica gel and the upper layer of a well shaken mixture of methyl ethyl ketone-water (50 + 50) (Fig. 189). Polymeric products ( condensates ) from reaction of ethylene oxide with fatty amines can be chromatographed in the upper phase of the mixture methyl ethyl ketone-2.5 % ammonium hydroxide... 

For the system cellulose acetate (E-398-3)/methyl ethyl ketone/water, B and D values are known to be 35.9 x 10 m and 1.92 x 10 m, respectively. Calculate the surface excess F/c>i of methyl ethyl ketone at the cellulose acetate/water interface.
