Yield:-

Reaction Conditions:

with lanthanum orthoferrite in water monomer at 154.84; under 3750.38 Torr; for 5 h;Sealed tube;Temperature;

Steps:

2.4. Batch reaction procedure

General procedure: A CWAO of 1 wt% D-glucose water solution was tested in a 300 mlbatch stirred reactor (Parr Instruments Company, 4566 model). In atypical experiment, a catalyst loading of 15 mol.% was set during thereaction; about 100 mg of fresh catalyst was added to 50 ml of solutionin all the catalytic tests. After sealing the reactor head, air was allowedto flow into the reactor headspace, as described in Ref. [38]. Beforeheating, the reactor was pressurized with air at 5 bar; 1 bar of partialoxygen pressure was maintained inside the chamber.Afterwards, the reactor was heated up until the desired temperaturewas reached, according to the experimental set point. The temperaturesand pressures of the system were recorded each minute with an acquisitionsoftware supplied by the Parr Instruments Company. The experimentswere carried out at the desired temperature set point and for thedesired duration; subsequently, the system was quickly cooled at roomtemperature, in order to stop the reaction and to carry out the productanalysis as soon as the test had finished [39]. At the end of the test, thecatalyst was separated through a filtration and the liquid phase wasprepared for analysis; the solid residue was washed 5 times with distilledwater and dried overnight at 353 K to remove physisorbed water; then itwas weighed and stored. The blank test was performed by adding about100 mg of SiO2 to the mother solution
