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 کاملA novel experimental approach to investigate radiolysis processes in liquid samples using collimated radiation sources.
Here is detailed a novel and low-cost experimental method for high-throughput automated fluid sample irradiation. The sample is delivered via syringe pump to a nozzle, where it is expressed in the form of a hanging droplet into the path of a beam of ionising radiation. The dose delivery is controlled by an upstream lead shutter, which allows the beam to reach the droplet for a user defined peri...
متن کاملN,N,N,N-Tetramethylguanidinium acetate as an efficient and reusable ionic liquid catalyst for the one-pot synthesis of dihydropyrrol-2-ones
An extremely facile and efficient procedure which has been developed for the synthesis of dihydropyrrol-2-ones. One-pot four-component reaction of amines, dialkyl acetylenedicarboxylates and formaldehyde in the presence of N,N,N,N-tetramethylguanidinium acetate [TMG][Ac] in methanol at ambient temperature provides substituted dihydropyrrol-2-ones in good to high yields. The important aspects of...
متن کاملbiodegradation of n-hexadecane in acinetobacter radioresistens liquid culture
background diesel oil hydrocarbons are the most common contaminants of our biological environment. considering the fact that iran is one of the major producers of diesel oil products, it greatly contributes to soil and water pollution. currently, soil and water pollutions caused by diesel oil products leakage, from distribution stations, is one of the major concerns in iran. based on the studie...
