متن کاملSelective Oxidation of Xylenes to Toluic Acids
A mixture of manganese, cobalt and lead para-amino benzoates supported on silica gel is used to catalyze oxidation of xylenes to toluic acids in presence of oxygen or air. Reactions are clean and catalysts can be recovered easily and reused.
متن کاملSurface stoichiometry and the initial oxidation of NiAl(110).
Selective oxidation of the surface of an ordered alloy requires redistribution of the atomic species in the vicinity of the surface. This process can be understood in terms of the formation and movements of point defects in the compound. On the basis of ab initio density-functional calculation we found both the creation of exchange defects near the NiAl surface and segregation of Ni vacancies t...
متن کاملOrigins of Nonstoichiometry and Vacancy Ordering in Sc12x xS
Whereas nearly all compounds AnBm obey Dalton’s rule of integer stoichiometry (n:m, both integer), there is a class of systems, exemplified by the rocksalt structure Sc12x xS, that exhibits large deviations from stoichiometry via vacancies, even at low temperatures. By combining first-principles total energy calculations with lattice statistical mechanics, we scan an astronomical number of poss...
