Catalytic conversion of alcohols XXI. Comparison of aluminum and molybdenum oxide catalysts

摘要: Abstract Molybdena, as a very selective dehydration catalyst, resembles alumina. Neither catalyst causes isomerization of the initial gas-phase alkene products. This was confirmed by adding similar to an alcohol reactant. However, molybdena produced products from some reactants that even required methyl migrations. For example, 4,4-dimethyl-2-pentanol with primarily β-elimination products, whereas isomeric 2,2-di-methyl-3-pentanol only about 10% remaining requiring migration. On basis distributions cyclic and acyclic alcohols, catalyzes E-1-like mechanism in contrast concerted for
