Abstract
Official abstract text for this publication.
The present invention discloses an improved oxidation process using carbon nitride nanotubes as metal free catalyst and molecular O2 as the oxidant to obtain desired adipic acid and other oxygenated hydrocarbons with improved conversion and selectivity.
First claim
Opening claim text (preview).
1 . A single step and metal free oxidation process for the preparation of oxygenated hydrocarbons with improved conversion and selectivity which comprises reacting the substrate with molecular O 2 in presence of carbon nitride nanotubes catalyst and a solvent. 2 . The oxidation process as claimed in claim 1 , wherein the process is carried out at temperature 100-140° C. 3 . The oxidation process as claimed in claim 1 , wherein 25-100 mg carbon nitride nanotubes catalyst was used for 0.15 mole of substrate. 4 . The oxidation process as claimed in claim 1 , wherein the solvent is selected form acetonitrile and acetone. 5 . The oxidation process as claimed in claim 1 , wherein oxygenated hydrocarbons is selected from the group consisting of acids, ketones and lactones. 6 . The oxidation process as claimed in claim 1 , wherein acid is adipic acid when substrate used is cyclohexane or cyclohexanone. 7 . The oxidation process as claimed in claim 1 , wherein ketones is 2-hexanone when substrate used is n-hexane. 8 . The oxidation process as claimed in claim 1 , wherein lactones is caprolactone when substrate used is cyclohexanone in the presence of benzaldehyde. 9 . The oxidation process as claimed in claim 1 , wherein selectivity of acids, ketones and lactones is in the range of −10-90%. 10 . The oxidation process as claimed in claim 1 , wherein conversion of n-hexane, cyclohexanone and cyclohexane is in the range of −10-70%.
