Radiolysis of Liquid Propane: non-Radical Reactions
The yields of ionic and excited molecule reactions in y-radiolysis of liquid propane from 35 to -130C have been assessed by isotopic analysis of C3Hs-l-C3Ds+Oz and CH3CD2CH3 -1-02 mixtures. From a comparison with gas phase data the following conclusions are reached for the gas to liquid phase change: (a) the ionic decomposition yield rlecreases by :5 69 %, (b) the net excited molecule decomposi...
متن کاملRadiolysis of Liquid Propane: Radical Reactions
The radical reactions in the liquid phase y-radiolysis of propane have been studied from -130 to 35°C and compared with the gas-phase radiolysis at 35°C. Oxygen was used as a scavenger 10 separate thermal radical yields, and effects· of phase and temperature on the radical yields were assessed. The gas-liquid phase change (a) decreases total decomposition by about 14 %, (b) increMCs disproporti...
متن کاملImmobilized Liquid Membrane for Propylene- Propane Separation
Separation of propylene-propane mixture using immobilized liquid membrane was investigated. The effect of transmembrane pressure and carrier concentration on membrane separation performance was studied. It was observed that for 30:70 (vol. %) propylene-propane mixture, at pressure of 120kPa and carrier concentration of 20wt. %, a separation factor of 474 was obtained. Keywords—Facilitated Trans...

The photoionization of isopropanol (i-PrO H) at 11.7 e V has been investigated in the NBS high pressure photoionization mass spectrometer over the pressure range 0.1 to approximately 200 millitorr_ The major primary ion, CHaCHOH+, reacts with a total rate coefficient of 1.1 ± 0_1 X 109 cma/molecule-s to yie ld mainly (i-PrOH)H+ and CH3(i-Ca H,)COH+ _ At pressures in excess of a few millitorr co...
متن کاملReactions of excited-state benzophenone ketyl radical in a room-temperature ionic liquid.
The photochemistry of the benzophenone ketyl radical in D(1) excited state, BPH(D(1)), was studied by means of two-color dual-pulse laser flash photolysis (355 and 532 nm) in a room-temperature ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide (Bmim-TFSA), and in methanol. Upon excitation with the 532 nm pulse, BPH(D(1)) emitted strong fluorescence. The transient absor...
