While the temperature rising up the color of the mixture changed to dark color green‚ reflux happen at 11.32 water droping back to the three necked flask. The compounds in the mixture checked by TLC ( Thin Layer Chromatography). After three attempt of the TLC‚ founded that there are 0‚86cm for Rf calue of the compounds.

solution was mixed added to 100 mL of ice water in a 250 mL flask. This flask was in an ice bath because low temperatures reduce solubility. The solution was added to a flask with a plastic pipette. The mixture was stirred at high speed. The mixture turned cloudy and white. The temperature was 3. The mixture was then poured through a Buchner funnel using vacuum filtration. The water and succinimide (the other product formed) collected in the flask below the funnel. This was the filtrate. BCHA stayed on

The mixture was boiled‚ the extracted first using water followed by aqueous sodium bicarbonate. The mixture was dried using anhydrous granular sodium sulfate. After dried‚ the sample was placed in a distillation apparatus and heated. This resulted in 1.8g of pure isopentyl acetate‚ a 44% yield. Introduction

Abstract In order to experiment with distinct components of a mixture‚ they must be first separated so they can be observed individually. This is accomplished in this lab by the technique called thin layer chromatography (TLC). TLC involves a stationary phase‚ which the TLC plates as well as a mobile phase‚ which could be one of two solvents used: ethanol-acetone for TLC. Dyes in a sample separate consequently because of their unique polarities. As a result‚ nonpolar substances travel further

In the software‚ the chromatogram was smoothed first column by 0.1 and second column by 1.0. For Blob detection function‚ the thresholds were set minimum area as 200‚ minimum volume as 15000 and minimum peak as 140.0 (relative reference). In the chromatogram‚ 6 corresponding peaks (A-F) were detected by the above mentioned algorithm
