The resulting mixture is saturated with sodium chloride, and the organic phase is separated and washed with three 50-ml. portions of saturated brine solution. The organic solution is dried over sodium sulfate and concentrated on a rotary evaporator. Distillation of the residue through a 7-cm. Vigreux column separates 15.34-15,99 g. (75-80%) of phenyl heptyl ketone, b.p. 118-120° (0.60 mm.) n2eD 1.5034 (Note 9). 

Phenyl heptyl ketone has been prepared by the Friedel-Crafts acylation of benzene with octanoyl chloride.6 It is also a product of the thermal decomposition of the mixed ferrous salts of benzoic and octanoic acids.7...

As would be expected from the Le Chatelier principle, the use of reduced pressure gave improved yields. n-Octyl alcohol at 125 to 135 mm. pressure yielded 73.9% di-n-heptyl ketone compared with 56.0% conversion obtained at atmospheric pressure. 

Catalytic conversion of l-Octanol-2-d to ketone A quantity (29.7 ml.) of l-octanol-2-d was charged (space velocity 0.2) to a 5-mm. reactor tube containing 18 ml. of 8- to 10-mesh chromium oxide catalyst maintained at 400°. The 27.7 ml. of liquid product was fractionated in a concentric-tube etjlumn. A 60.6% yield of di-n-heptyl ketone was obtained. Approximately 17% of the alcohol was recovered "unconverted. Mass spectrometric analysis of the gaseous product showed the atomic ratio of deuterium to hydrogen to be 0.106. The molal yields of deuterium, hydrogen, and carbon monoxide produced per mole of ketone were 0.216, 2.040, and 0.815 respectively. 

Di-n-heptyl ketone and the di-n-heptyl ketone prepared catalytically from l-octanol-2-d were examined in carbon tetrachloride solutions with a cell having a path length of 1.0 mm. The ketone prepared from 1-octa-nol-2-d showed an absorption band characteristic of C-D at 4.63 of di-heptyl ketone. The number of C-D bonds per ketone molecule was estimated to be in the range of 1.0 to 1.5. A more accurate estimate of the C-D content of the ketone would require a reference sample of deuterated ketone, which was not available.
