Effect of Hydrogen on Action of Aluminum Chloride on Alkanes

The Hydride-Transfer Reaction.

“…The donation of hydride ion to carbon by molecular hydrogen is indicated by the conversion of propene to propane by hydrogen gas in the presence of aluminum chloride (40). Molecular hydrogen also inhibits the cleavage of alkanes in the presence of aluminum halides (11,13,38,40,64). This effect has been usually interpreted in terms of donation of hydride by molecular hydrogen to the intermediate alkyl cations.…”

Isomerization of n-Pentane - Effect of Various Additives

“…Densities and viscosities may be determined easily and accurately with comparatively simple apparatus. Various methods for the determination of vapor pressures on a small quantity of pure liquid have appeared in the literature (4,8,17). However, all have certain serious limitations and usually yield erroneous results when used outside those limits of temperature and pressure to which they seem to be intrinsically adapted.…”

Anhydrous Aluminum Bromide in Organic Solvents

“…The product obtained showed gradual progressive signs of deterioration, not only in the aluminum bromide value, but the entire solution. The causes and implications have been defined and theoretically discussed (Grosse and Ipatieff, 1936;Ipatieff and Schmerling, 1948;Lien et al, 1952;Mavity et al, 1948;Obald and Gorin, 1946; Pines and Wackher, 1946). The mechanism and chemistry of the disproportionation reaction have also been discussed (Brooks, 1950; Olah, 1963;Thomas, 1941).…”
