COLUMN AND THIN LAYER CHROMATOGRAPHY Group 9 RAMOS‚ Sharina Joy; REYES Aina Marie; REYES Jallisa Maan; RUBIO‚ John Michael; SABINO Patricia Anne; SANTOS‚ Carlos Rafael ABSTRACT To separate the colored components of siling labuyo and to determine the purity of the components‚ the students performed a column and thin or solid-liquid chromatography procedure. The solid may be almost any material that does not dissolve in liquid phase. But for this experiment‚ the solid used by the students was

It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with

Discussion Using the Thin Layer Chromatography experiment‚ caffeine was found to be the most polar due to the fact that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted

the slurry to be placed on the glass plates. A guide allows the applicator (with an adjustable layer thickness gauge) to be pulled along the glass plates as the slurry is dispensed. Some practice is needed to get a continuous body motion pulling the applicator across the plates to get an even layer. The glass plates must be the same thickness and extremely clean. Any oil or grease will result in a poor layer. Handle the plates with rubber gloves when washing or rinsing. Care is also needed if the edges

a useful solvent for many chemical processes. The solid was already in powder form therefore we did not have to crush it but it the unknown was in a tablet form‚ one would need to reduce it to a powdery-like form in order to perform this Thin-Layer Chromatography experiment. The powder solution was thoroughly mixed with a glass rod in the test tube containing
