Column chromatography separation of fluorene and 9 -fluorenone reading please read unit 9 for packing the micro column, see “packing and running the column” on pp 210-. Reduction 1 experiment 1: the borohydride reduction of 9-fluorenone to 9-fluorenol background: in this week’s experiment, a metal hydride will be used as a reducing agent. Write a balanced equation for the reduction of 9-fluorenone to 9-hydroxyfluorene by sodium borohydride also, what is the limiting reagent 200 mg (111 mmol) of 9-fluorenone in 25ml of absolute ethanol is reacted with 50 mg (132mmol) of sodium borohydride. Fluorenone can be prepared from fluorene by contacting a solution of the latter in dimethyl sulfoxide with molecular oxygen in the presence of a small amount of an alkali-metal hydroxide.
Preparation of fluorenone 10 g of fluorene, 30 g of coarsely ground sodium bichromate, and 40 g of glacial acetic acid are boiled under a reflux condenser for two to three hours. Experiment 3 - reduction of a ketone in this experiment we will reduce fluorenone to fluorenol using nabh 4 in methanol equation figure 2 stoichiometry note. Column chromatography of fluorene and fluorenone post lab #4- column chromatography organic chem 3418-2 march 3, 2011 theoretical background- the fluorene and fluorenone mixture was separated by first dissolving the mixture in heptane. Fluorene page 2 of 6 this fact sheet is a summary source of information of all potential and most severe health hazards that may result from exposure.
Purpose:to improve the production process for fluorenone by oxidizing fluorene dispersed in a mixture of agueous sodium hydroxide and an organic solvent immiscible with water with molecular oxygen in the presence of a quaternary ammonium salt. Fluorene: 86-73-7: 5000 pounds (epa list of lists, 2015) dhs chemical facility anti-terrorism standards (cfats) no regulatory information available alternate.
The goal of the first part of this experiment was to achieve a 50-50 conversion of fluorene to fluorenone in order to achieve the goal of the experiment fluorene was oxidized to fluorenone. Answer to air oxidation of fluorene to 9-fluorenone (the pictures below have the lab procedure and chemical equations need) 1 des.
