1 -Ethyl-4- hydro

If in an odoriferous body the atoms with which the possibility of free affinity exists be replaced by others where such possibility does not exist the odour is removed. Thus cacodyl would yield the odourless ethane methyl iodide would give methane ethyl hydro-selenide would yield ethane, and so on.

An important application of the critical solution temperature is to the determination of the water content in such substances as methyl and ethyl alcohols. Here the system is usually the alcohol and a hydro carbon, such as -hexane or dicyclohexyl the water is, of course, insoluble in the hydrocarbon. Thus, the methyl alcohol - cyclohexane system has a C.S.T. of 45 -5° and even 0 01 per cent, of water produces a rise of 0-15° in the C.S.T. The experimental details are given below.

Phenyl-propyl alcohol, CgH. CHj. CH.2. CHj. OH, is the next highest homologue of phenyl-ethyl alcohol, and is also known as hydro-cinnamyl alcohol. Like the last described bodies it has been known for many years, its first preparation being described in the Aivnalen (188, 202). It occurs as a cinnamic acid ester in storax, and as an acetic ester in cassia oil. It is prepared synthetically by the reduction of cinnamyl alcohol with sodium amalgam and water, or by the reduction of cinnamic or benzyl acetic esters with sodium and absolute alcohol. It has the following characters —...

D/chloro-5-Cyclohexyl-2-Oxo-2,3-D/hydro 1 H-Benzo(fj-Diazepine-1,4 fa) Process Using Sodium Hypochlorite — 40 ml of a solution of sodium hypochlorite of 14.5 British chloro-metric degrees are added to a suspension of 5.4 grams of 7 chloro-5 cyclohexyl-2 oxo-2,3-dihydro 1 H-benzo(f)diazepine-1,4 in BO ml of methylene chloride. The mixture is stirred at room temperature for 15 minutes the solid dissolves rapidly. The organic iayer is decanted, washed with water, dried over anhydrous Sodium sulfate and the solvent evaporated under reduced pressure without exceeding a temperature of 30 C. The residue is taken up in a little diisopropyl ether and the crystals which form are dried. They are recrystallized as rapidly as possible from ethyl acetate. Colorless crystals are obtained (3.9 grams yield, B5%) MP < = 163°C, with decomposition.

Broxton and Bunnett (1979) determined the products of the reaction of 4-chloro-3-nitrobenzenediazonium ions with ethoxide ion in ethanol, which is exactly analogous to the reaction in methanol discussed earlier in this section. These authors found 12.8% 4-chloro-3-nitrophenetole, 83% 2-chloronitrobenzene, and 0.8% 2-nitrophenetole. When the reaction was carried out in C2H5OD, the first- and second-mentioned products contained 99% D and 69% D respectively. Dediazoniation in basic ethanol therefore results in a higher yield of hydro-de-diazoniation with this diazonium salt compared with the reaction in methanol. This is probably due to the slightly higher basicity of the ethoxide ion and to the more facile formation of the radical CH3-CHOH (Packer and Richardson, 1975). Broxton and McLeish (1983 c) measured the rates of (Z) — (E) interconversion for some substituted 2-chlorophenylazo ethyl ethers in ethanol.
