Isopentyl Acetate Synthesis

ISOPENTYL ACETATE SYNTHESIS Post-Lab Submitted by Vivian M. Chan Teaching Fellow: recollective Nguyen Calculations and stopping point: In this lab, isopentyl acetate rayon was synthesized by have isopentyl alcohol and acetic acid. In this reaction, molecules were joined through the intermolecular elimination of water. A method of liquid extraction was practice to wash the intersection point with water, sodium Bicarbonate and atomic number 11 Chloride. Simple Distillation was used to cure a more concentrated intersection point. The final lowbred product yield was 0.91g and the vestal product yield was 0.36g. defect may turn in occurred during the extraction phase. Although I extracted twice with Sodium Chloride, if waste was non completely removed, it would adjoin the purity of the product. The distillate process may have also affected the pure product. The lab manual of arms recommended that 0.5mL of waste be removed during distillment; otherwis e it would affect the purity of the product. During distillation, a plastic pipet was used. It was difficult to retrieve the waste because the pipet could not make water without the implement at a certain angle. By the cadence I switched to a glass pipet, there may have been unneeded of 0.5mL. In attempt to remove all the waste, I as removed from 0.5mL of product. During the dry outing stage, 0.

5g of anhydrous sodium sulphate was recommended to dry the crude ester, approximately 2g of anhydrous sodium sulfate was used. This seemed like an excess of anhydrous sodium sulfate however may not have affected the pure product in the long run. The product yielded produ! ced a scent of a banana tree which is consistent with the production of banana oil. This par displays the synthesis of isopentyl acetate by Fischer Esterification between isopentyl alcohol and acetic acid with sulphuric acid as the catalyst. IR abstract: The above below was retrieved from IR Spectrum. There were 3 peaks that was in addition to a defined peak that may be been caused by echo or impurities of the sample....If you want to get a full essay, pose it on our website: BestEssayCheap.com
