Ethylene-oxygene-nitrogen

Method. Rich ethylene-oxygen—nitrogen flames are stabilized on a cylindrical burner which is enclosed in a vessel fltted with quartz windows. Metals are added to the flames by electrically heating a pearl of salt (nitrates or chlorides) introduced into the nitrogen flow, and their concentration is determined from loss of weight. 

Liquified gases such as ethylene, oxygen, nitrogen, and hydrogen are typically stored in double-wall spheres, where the inner tank is suspended from the outer tank by straps or cables and the annular space between the tanks is filled with insulation. I he outer tank is not subjected to the freezing temperatures and is thus designed as a standard carbon steel sphere.

Protons attached to sp carbons are more acidic than protons attached to nonallylic sp carbons. Also, the inductive effect of a heteroatom further increases the acidity of an adjacent sp C-H bond, facilitating a-lithiation. The relative activating effect of heteroatoms is sulfur > oxygen > nitrogen. Thus, treatment of 2-ethoxy-l-(phenylthio)ethylene with t-BuLi results in exclusive lithiation at the phenylthio substituted carbon. ... 

Hydrocarbons in the exhaust react with oxygen and with NO. Although these reactions have had much less attention than oxidation of CO and reduction of NO by CO, reactions of hydrocarbons play an important role in the overall reaction mechanism of the three-way converter, particularly because the converter is by no means a homogeneously mixed reactor, see Fig. 5.15 [57]. Hence, zones exist where e.g. ethylene and nitrogen atoms are coadsorbed on the noble...
