An experiment on the synthesis of acetylferrocene

Pour the solution over the ice. The melting temperature analysis is completed on the second day. Replenish with solvent as needed. Compressed air at a low pressure is used to flash the solvent through the column to accelerate the procedure. Close the stopcock to leave in. Prepare the reaction mixture. This experiment can be divided into two days. Direct a gentle stream of air low flow to help dry the solid. Collect the orange precipitate by vacuum filtration. Weigh the filter paper and record the mass to the nearest 0. The synthesis and chromatography are completed on the first day. Repeat Step 25—27 for the acetylferrocene sample. Severe eye and skin irritant. Once the solvent has drained to just above the silica, pipet your sample evenly onto the column. Silica: Moderately toxic by inhalation and ingestion.

May cause eye and skin irritation. While allowing the column to drain very slowly, add the alumina slurry to the column via a short stem pipette. Connect the Melt Station power supply to a powered electrical outlet. Rosettes of dark orange-red needles of acetylferrocene will form and may be collected by vacuum filtration on a Buchner funnel.

Melting temperature analysis will be used to characterize the synthesized product. If only one ring reacts, then the product is the orange acetylferrocene.

In the first trial, you will want to observe the melting process and make a rough estimate of the melting temperature of your sample. Organic Chemistry with Vernier 7 Sodium bicarbonate: May be harmful by ingestion or inhalation.

If both rings react, then the product is the red 1,1-diacetylferrocene.

ferrocene and acetylferrocene

Add a stir bar to the flask. Carefully observe the temperature vs. Carefully insert the capillary tube of solid into one of the sample holders of the Melt Station. Open the stopcock slightly to allow some solvent to pass into a collection vessel clearing out any major air bubbles trapped in the glass wool or sand layers.
