10% peroxide and 80-92 vol.% propane. 5-15 vol.% oxygen may be present as catalyst. By-product No is converted to the peroxide for recycling. The reduction in temp. from above 350 degrees C when using HNO3 reduces the formation of nitriles resulting in higher yields....
A reaction that is slowed by the addition of a free-radical inhibitor can be assumed to proceed by a radical mechanism. Common radical inhibitors include 2,6-di-t-butyl-4-methylphenol (butylated hydroxytoluene, BHT), 2-nitroso-2-propane, and oxygen. Sign in to download full-size image BHT...
On oxygen-activated Ag(110) 1,2-propanediol reacts with O by 215 K to form adsorbed 1,2-propanedioxy OCH(CH )CH O and water. 1,2-propanedioxy is stable up to 285 K, at which temperature C-H bond scission begins. A mixture of acetol CH C( O)CH OH and, most probably, lact...
The bond between 'Ga' and the dot represents the multiple bonds between the gallium ion and oxygen nuclei of the silica surface. Each reaction arrow is labeled with the electronic activation energy of the reaction in kJ mol−1. Barrierless reactions, both endo- and exothermic, are labeled ...

摘要: The catalytic properties of a Mo–V–Te–Nb–O mixed metal oxide catalyst were investigated in the selective oxidation of propane and its corresponding partial oxidation intermediates. Propane oxidation pathways are proposed based on experimental findings.关键词:...
Understanding the sensing mechanism of metal oxide semiconductors is imperative to the development of high-performance sensors. The traditional sensing mechanism only recognizes the effect of surface chemisorbed oxygen from the air but ignores surface la
How many carbon dioxide molecules are produced when 0.75 mol of propane is combusted according to this equation? C3H8+5 O2→3 CO2+4 H2OC3H8+5 O2→3 CO2+4 H2O Show Answer Check Your Learning How many NH3 molecules are produced by the reaction of 4.0 mol of Ca(OH)2 according to the...
be noted, however, there can be three types of Ga species:Ga ionsincorporated intosilicate framework, dispersed extraframework Ga species, and Ga2O3particles. Present study aims at identifying the catalytic sites limiting the conversion of propane and the formation of aromatics overgallosilicateofMOR...
Recently, this inhibition has been studied in more detail by examining the effect of the simpler hydrocarbons on the second limit of hydrogen - oxygen mixtures in clean and potassium chloride-coated Tyrex' vessels. With propane, as with the higher hydrocarbons studied earlier, an almost linear ...
