Ethane Nitrous oxide

The proton NMR spectrum shows chem shifts of 6.93 5.957- (Ref 1). Photolysis with a Hg arc lamp gives N, nitrous oxide, methane, and ethane (Ref 2). It was found to produce colon and rectal carcinomas in rats after oral administration at 12mg/kg weekly, induction period 235 days (Ref 3)... 

Thermal Decomposition. The therm decompn was studied betw 380 and 430° and found to be homogeneous and apparently 1st order. The products were complex and included nitric oxide, methane, carbon monoxide, and w plus small amts of ethane, ethylene, and nitrous oxide (Ref 23)... 

Diethyl ether was the inhalation anesthetic of choice during my childhood. Happily, 1 had rather little need of it. Ether was replaced years ago by a family of superior inhaled general anesthetics, most of which are ethane derivatives. The notable exception is another very simple molecule, nitrous oxide, N2O, frequently known as laughing gas. N2O has been around for a long time and was once a party drug. ... 

The best-known gas hydrates are those of ethane, ethylene, propane, and isobulaue. Others include methane and I butene, most of the fluorocarbon refrigerant gases, nitrous oxide, acetylene, vinyl chloride, carbon dioxide, methyl and ethyl chloride, methyl and ethyl bromide, cyclopropane, hydrogen sulfide, methyl mercaptan, and sulfur dioxide. 

J. P. Kuenen studied the vap. press, of mixtures of liquid ethane and nitrous oxide. W. Nernst gave 3-3.for the chemical constant, and W. Herz discussed this subject. 

Studiengesselschaft Kohle m.b.H. (2) reported the effect of temperature on solubility level in supercritical gas. The solubility is highest within 20 K of the critical temperature and decreases as temperature is raised to 100 K above the critical temperature. At temperatures near the critical temperature, a sharp rise in solubility occurs as the pressure is increased to the vicinity of the critical pressure and increases further as the pressure is further increased. Less volatile materials are taken up to a lesser extent than more volatile materials, so the vapor phase has a different solute composition than the residual material. There does not seem to be substantial heating or cooling effects upon loading of the supercritical gas. It is claimed that the chemical nature of the supercritical gas is of minor importance to the phenomenon of volatility amplification. Ethylene, ethane, carbon dioxide, nitrous oxide, propylene, propane, and ammonia were used to volatilize hydrocarbons found in heavy petroleum fractions. 

Using an 800 mV applied voltage, the response of the sensor has been evaluated in the range of 12-100% CH4 in air (Fig. 7.18). Major interferences have been caused by the presence of nitrous oxide, ethane, hydrogen, and carbon monoxide. Other sensors of this type have been described, but they differ only in the details of the design and not significantly in the concept. 

Other substrates reduced by nitrogenase include azide (which gives ammonia, dinitrogen, and hydrazine) (151), diazomethane (ammonia and undisclosed products), nitrous oxide (dinitrogen and water), hydrocyanic acid (methane and ammonia), cyanide (methane and ammonia), methyl isocyanide, and other organoisonitriles (methylamine, methane, ammonia, ethane, and other higher hydrocarbons). 

The ratio of nitrogen formed in the photolysis of pure N20 to that formed under identical conditions in a nitrous oxide-ethane mixture is...

Some compounds which are gases at normal temperature and pressure can be detected by head-space gas chromatography (p. 187), using Systems GA or GI (p. 199). System GI will detect butane, ethane, methane, nitrous oxide, and propane, and... 

Of the numerous poisoning experiments that indicate heterogeneity of catalyst surfaces, reference may be made first to a study of selective poisoning made by Russell et al. (83,84). Russell and Ghering found that the rate of the hydrogenation of ethylene over reduced copper was not markedly affected by nitrous oxide but that the rate of ethane formation decreased rapidly as soon as the adsorbed nitrous oxide was decomposed. 

Carbon dioxide, water, ethane, ethylene, propane, ammonia, xenon, nitrous oxide, and fluoroform have been considered useful solvents for SEE. Carbon dioxide has so far been the most widely used as a supercritical solvent because of its convenient critical temperature, 304°K, low cost, chemical stability, nonflammability, and nontoxicity. Its polar character as a solvent is intermediate between a truly nonpolar solvent such as hexane and a weakly polar solvent. Moreover, COj also has a large molecular quadrupole. Therefore, it has some limited affinity with polar solutes. To improve its affinity, additional species are often introduced into the solvent as modifiers. For instance, methanol increases C02 s polarity, aliphatic hydrocarbons decrease it, toluene imparts aromaticity, R-2-butanol adds chirality, and tributyl phosphate enhances the solvation of metal complexes.
