Reaction Between Methane and BromineJim Clark
溴與bis(3.5-di-tert-butyl-4-hydroxyphenol)methane(I)的反應由實驗結果得知,具立體障礙的酚類(如4-substituated-2,6-di-t-butylphenols)與溴照光下反應,可得同位取代的反應物。當(I)與過量溴照光反應後,除進行氧化反應得產物(II)外尚可行(II)的同位取代反應,而(I)的四氯化碳溶液與溴在廻流條件...

Gaseous Reactions of Methane and Various Polyhalomethanes with Bromine and Iodine Activated by the (n, gamma) Process In the presence of a large excess of gaseous methane, 54.4±0.5% of I128formed by (n,γ) activation was found to become stabilized in organic combination. ... E Rack 被引...
Methyl bromide was synthesized by reacting methane with oxygen and hydrogen bromide over Rh/SiO2 catalyst. The reaction started from the oxidation of HBr to form active bromine species (Br radicals and Br* surface species), which in turn reacted with CH4 to form CH 3 radicals and $$\\hbox...
Tetrachloromethane is a compound that can be used to replace a single iodine in iodoform by stirring a mixture of iodoform and bromine in the presence of tetrachloromethane for a specific duration. AI generated definition based on: Comprehensive Organic Functional Group Transformations, 1995 ...
Here, photoelectron photoion coincidence spectroscopy with synchrotron radiation was used to provide evidence of the evolution of gaseous methyl and bromine radicals over (VO)2P2O7 and EuOBr catalysts and the strong correlation between the formation of methyl radicals and the production of bromo...
Reacts violently with powerful oxidzers (e.g., bromine pentafluoride, chlorine trifluoride, chlorine, fluorine, iodine heptafluoride, dioxygenyl tetrafluoroborate, dioxygen difluoride, trioxygen difluoride, liquid oxygen, ClO2, NF3,OF2). Incompatible with halogens or interhalogens in air (forms ...
However, it is not possible to carry out the exact reaction between methane and oxygen to develop methanol when the temperatures are over 200 degrees. Otherwise it will result in methanol burning. It is necessary to repeatedly heat and cool the reaction vessel. This is the reason why this ...
Reactivity ProfileMETHANE is a reducing agent, METHANE is involved in many explosions when combined with especially powerful oxidizers such as bromine pentafluoride, chlorine trifluoride, chlorine, iodine, heptafluoride, dioxygenyl tetrafluoroborate, dioxygen difluoride, trioxygen difluoride and liquid oxygen....
