M Octyl bromide

In place of w-octyl iodide other derivatives such as M-octyl bromide, w-octyl -toluenesulfonate, and w-octyl chlorosulfonate can be substituted the submitter reports that the yields of octanal in these cases are comparable. 

R-Octyl bromide [111-83-1] M 193.1, b 201.5 , df 1.118, n 1.4503. Shaken with H2SO4, washed with water, dried with K2CO2 and fractionally distd. 

Elemental phosphorus reacts with alkyl and aryl halides to give products that vary according to the experimental conditions. When heated with white phosphorus in a bomb tube at 250-300°, benzyl chloride, bromobenzene, m-bromotoluene, and octyl bromide give mixtures of halo and dihalo phosphines, sometimes in appreciable yield ... 

CgHi-)POH. IS obtained from the corresponding hiomide, which is the condensation product of tri-zi-propylphosphine and H-octyl bromide. The liquid bromide may be converted to the iodide by means of sodium iodide m alcohol, or into the chloi ide through the hydroxide, but these bait > are also liquids. The chloioaunite separates from alcohol m prisms, M.pt. C. Distillation of the hydroxide gives a 19-8 per cent, yield of octane and a GG-2 per cent, yield of propane.

In fact, we do have alkyl fluoride enthalpy-of-formation data for liquid -heptyl and H-octyl fluoride. Reference 1 cites, - 385 and - 439 kJmoL1 derived from the compendium by M. S. Kharasch, Bur. Stand. J. Res., 2, 359 (1929). A major problem—other than that the difference in enthalpies of formation is unreasonable—is found in Kharasch s work. He gives two -octyl fluoride heat-of-combustion values (one from the bromide, one from the iodide, and acknowledges the samples have a boiling point difference of 0.60°) that differ by 19.2 kJmoT1. The original study of the enthalpies of formation of n- and isopropyl fluoride is found in J. R. Lacher, A. Kianpour and J. D. Park, J. Phys. Chem., 69, 1454 (1956). Early in this paper, the authors... 

The first term on the right-hand side of equation (8.7) is the contribution of the head group repulsion, while the second is the interfacial energy contribution where Ahg is the total surface area of the head groups and (Tmic is the interfacial tension. Within the framework of the Gouy-Chapmann theory, the dressed micelle model allows the estimation of values, which are for sodium dodecyl sulfate (SDS), sodium octyl sulfate, and teradecyltrimethylammonium bromide, 15-16, 11 and 11-14 mN m , respectively (15). Note that these values are up to a factor of 3 lower than those of the pure monomers (cf. Table 8.2). A further decrease of or is possible in the case of emulsions of organic liquids where the interface is saturated with stabilizer. For example, a value of about 4 mN m was determined for a toluene emulsion stabilized with potassium lau-rate (16).
