Abstract
A method of oxidizing an organic alcohol, wherein the organic alcohol is contacted with a stoichiometric excess of oxygen in the presence of an effective catalytic amount of a maganese-containing octahedral molecular sieve or octahedral layer. Primary alcohols are selectively oxidized to aldehydes, and secondary alcohols are selectively oxidized to ketones.
Claims23
A method of oxidizing a primary or secondary organic alcohol, comprising:
- contacting the primary or secondary organic alcohol with a stoichiometric excess of oxygen in the presence of an effective amount of a manganese-containing octahedral molecular sieve or a manganese-containing octahedral layer material.
A method of oxidizing a primary or secondary organic alcohol, comprising:
- contacting the primary or secondary organic alcohol with a stoichiometric excess of oxygen in the presence of an effective amount of a manganese-containing octahedral molecular sieve or a manganese containing octahedral layer material;
- wherein the manganese-containing octahedral molecular sieve is co-synthesized to comprise gamma-manganese dioxide.
A method of oxidizing a primary or secondary organic alcohol, comprising:
- contacting the primary or secondary organic alcohol with a stoichiometric excess of oxygen in the presence of an effective amount of a manganese-containing octahedral molecular sieve or a manganese-containing octahedral layer material;
- wherein the manganese-containing octahedral molecular sieve is co-synthesized to comprise gamma-manganese dioxide and has the formula
- A2−yMn8O16.xH2O
- wherein A is H+, Na+, or K+, y is about 0.5 to about 1.5, and x is 0 to about 20.
A method of oxidizing an organic alcohol, comprising:
- in a solvent, contacting a primary or secondary cycloaliphatic, allylic, or benzylic alcohol with a stoichiometric excess of oxygen in the presence of a manganese-containing octahedral molecular sieve having a one-dimensional tunnel structure, wherein the molecular sieve is present in an amount effective to oxidize the primary cycloalphatic, allylic, or benzylic alcohol to an aldehyde or the secondary cycloaliphatic, allylic, or benzylic alcohol to a ketone.
A method of oxidizing a primary or secondary organic alcohol, comprising:
- contacting the primary or secondary organic alcohol with a stoichiometric excess of oxygen in the presence of an effective amount of an manganese-containing octahedral molecular sieve having the formula
- A2−yMn8O16.xH2O
- wherein A is H+, Na+, or K+, y is about 0.5 to about 1.5, and x is 0 to about 20.
