M-Hexyl alcohol

M-Hexyl alcohol has been prepared by the reduction of ethyl caproate by means of sodium and absolute alcohoB alone or in anhydrous ammonia solution by the reduction of -caproamide by means of sodium and absolute alcohol by the reduction of -caproaldehyde by means of sodium amalgam in dilute sulfuric acid and by means of living yeast, It has also been produced by the action of nitrous acid upon w-hexylamine by the action of sodium upon a mixture of ethyl alcohol and M-butyl alcohol ...

Plasticizer. The polymer tubing extractor contains the plasticizer l,2-bis(ethylhexyl) phthalate. Longer exposures to 0.1 M NaOH indicated that electroactive hydrolysis products of plasticizer, probably ethyl and hexyl alcohols, were produced, as suggested by the following peak currents given in nanoamperes (the times of the peak currents are given in parentheses) 30 (2 min), 7 (1 min), 5 (30 s), and 2 (15 s). The analytical procedure presented here uses back extraction times of less...

Use a numerical method from appendix C to determine the relative surface excess of -hexyl alcohol at c= 1.25,2.5, and 5 x 10 M. Assume that Henry s law holds for the solute in the given concentration range. Express the results in units of mol m and molec nm . ... 

The expression (II.3) allows one to calculate the approximate maximum value of substance adsorption, e. g. hexyl alcohol in the present case. If we assume that the thickness of the closely packed adsorbed layer is close to the length of the hexanol molecule ( 0.7 nm), and that the alcohol concentration, c)s), is close to its concentration in the liquid phase (=8 kmol m 3), then the adsorption, T, is 0.6 xlO 5 mol m2. 

This research was supported by a generous fellowship grant from the Houdry Process Corporation, to whom the authors wish to express their thanks. The mass spectra analyses were performed at the Houdry Process Corporation under the direction of Mr. J. Terrell. The authors also wish to thank Dr. M. R. Fenske for pure samples of the hexyl alcohols used to calibrate the mass spectrometer.

FIGURE 5.21 High-speed isothermal separation of a 20-component mixture using a pressure-tunable column ensemble. The plots of band position versus time were obtained from the retention factors for the mixture components on the two separate colimms along with the column dimensions and the inlet, outlet and junction point pressures. A window diagram was used to determine the junction point pressure for the complete separation of the first 14 components. Compounds are 1, n-pentane 2, methyl alcohol 3, 2,2-dimethylbntane 4, 1,1,1-trichloroethane 5, cyclopentane 6, w-hexane 7, w-propyl alcohol 8, cyclohexane 9, benzene 10, n-heptane 11, l,2-dichloropropane 12, toluene 13, n-bntyl alcohol 14, w-octane 15, 2-hexyl alcohol 16, n-pentyl alcohol 17, ethylbenzene 18, m-xylene 19, w-nonane 20, o-xylene.

Chemical/Physical. Hydrolyzes in water to o-phthalic acid (via the intermediate 2-ethyl-hexyl hydrogen phthalate) and 2-ethylhexyl alcohol (Kollig, 1993 Wolfe et al., 1980). Although no pH value was given, the reported hydrolysis rate constant under alkaline conditions is 1,400/M-yr (Ellington et al., 1993 Kollig, 1993). A second-order rate constant of 1.1 x 10 /M-sec was reported for the hydrolysis bis(2-ethylhexyl) phthalate at 30 °C and pH 8 (Wolfe et al., 1980).
