Purifying Acetanilide by Recrystallization Results: Acetanillide Solubility of acetanilide in water is 5.5g/100mL at 100C 0.53g/100mL at 0C PERCENT YIELD/THEORETICAL YIELD: Discussion: Acenatilide is a synthetic organic compound introduced in therapy in 1866 as a fever-reducing drug. Its effectiveness in relieving pain was discovered soon thereafter‚ and it was used as an alternative to aspirin. The solvent that I selected to recrystallize the

Although‚ I am not a movie watcher‚ it drew my full attention as soon as I started playing it. It displays the character of a great mathematician John Nash who is struggling with schizophrenia during his college period

The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously

The Equilibrium Constant of an Ester Hydrolysis Reaction Julia Stanley CHM 152 LL Dr. Asmita Kane Budruk Goal of the lab: The purpose of this laboratory is to determine the equilibrium constant‚ Kc‚ for the acid-catalyzed reaction between an unknown ester and water to produce an unknown alcohol and an unknown carboxylic acid. I was using Unknown Ester #3 with a density of 0.9342 and Molar Mass of 74.08 g/mol; alcohol with density 0.7914 and Molar Mass 32.04 g/mol. Chemical

For Acidic hydrolysis‚ SAC was found to be well susceptible to acid hydrolysis with 0.05 M HCl at 40 ˚C for 30 min caused about 8% reduction in the peak area of SAC (Fig.4a). While this mild condition didn’t affect VAL. While‚ nearly 27% was the reduction in SAC’s peak area when subjected to alkaline hydrolysis. This considerable decline in the peak area of SAC when subjected to 0.01 M NaOH at 40°C for 30 min revealed degradation products peaks appeared at 3.339 and 9.482 minutes (Fig.4b) and they

That is‚ the entering group does not for the most part have the same position on the ring as that purged by the halogen substituent. Case in point‚ the hydrolysis of 4-chloromethylbenzene at 340° gives an equimolar mix of 3-and 4-methylbenzenols: Significantly all the more striking is the elite development of 3-methoxybenzenamine in the amination of 2-chloromethoxybenzene.

Determination of the Equilibrium Constant of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1. Introduction In this lab the equilibrium constant‚ Kc‚ for the acid catalyzed reaction
