1-Hexene was oligomerized at 200°C and a pressure of 5 MPa in a down-flow fixed-bed tubular reactor filled with beidellite or ultrastable Y zeolite catalysts. Vapor, liquid, and supercritical states of the reacting hydrocarbons in the reactor tube were established by using propane, pentane, octane, and dodecane as solvents. The initial activity, stability with operation time, and selectivity are very dependent on the physical state of the hydrocarbons. Highest activity and stability are reached in the liquid phase using octane and dodecane solvent. The chain length of the solvent has a strong influence on the deactivation of the catalyst, on the oligomerization selectivity and on the formation of C6 saturates and cracked products.
RADIATION CHEMISTRY OF N-HEXANE AQUEOUS SOLUTIONS AS STUDIED BY CHROMATOGRAPHIC ANALYSIS OF FINAL PRODUCTS

Radiolysis of dilute oxygen-free hexane aqueous solutions give dodecanes isomers analyzed by capillary gas chromatography.The relative yields for radicals which react by radical-radical recombination reactions are 39 percent, 32 percent and 29 percent for primary hexyl radical, secondary-2 hexyl radical and secondary-3 hexyl radical respectively.This distribution is changed with the N2O saturation before the radiolysis to 22 percent, 42 percent and 37 percent.If the first distribution is statistic, the increase of OH. available to attack the solute gives the distribution existing in pure alkane radiolysis.
