Negative ion formation in potassiumâ•finitromethane collisions

Ion-pair formation in gaseous nitromethane (CH3NO2) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most dominant product anions are NO2 , O , CH3NO2 ,...

Negative ion formation in potassium-nitromethane collisions.

Ion-pair formation in gaseous nitromethane (CH(3)NO(2)) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most dominant product anions are NO(2)(-), O(-)...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

H 2 formation in space : a negative ion route ?

A new proposal is put forward for the formation of H 2 from H atoms in the interstellar medium based on the conjecture that efficient production of H − may take place at the surface of dust grains via attachment of weakly bound surface electrons. Subsequent gas phase associative detachment of H and H − forms H 2. The model is shown to be compatible with known properties of the interstellar medi...
