Isomerization of n-Pentane - Effect of Various Additives

Paraffin Isomerization with Hydrogen Chloride-Promoted Dual Function Catalysts

“…In the case of aluminum chloride-hydrogen chloride type catalysts large amounts of benzene inhibit isomerization. With these latter systems about 0.5 volume % benzene represents an optimum with respect to conversion and selectivity (4).…”

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).…”

A Small-Scale, High Pressure Recycle Gas System

“…is controlled by the adjustable backpressure throttling regulator (6). The two pressure regulators in series (4,5) maintain the suction pressure above 4 inches of water under all conditions of gas flow bybleeding gas from the high-pressure side to the suction side of the compressor. A maximum suction pressure of 12 inches of water is maintained by a simple water leg (16) to protect the overflow legs (±7 ft.) in the scrubbing system.…”
