Mechanism of chalcone formation Kinetic studies have been reported for the base-catalyzed formation of chalcone and its derivatives. [7‚ 8‚ 9] Two alternative mechanisms have been advanced for the reaction of benzaldehyde with acetophenone in the presence of a basic catalyst. 5 The formation of chalcone by the acid catalyzed condensation of acetophenone and benzaldehyde has been studied [10]. The following mechanism seems to be operating- 6 Importance of chalcones [1]They have close relationship

Experiment 13: Synthesis of 1-Bromobutane An SN2 Reaction Experiment #13: Synthesis of 1-Bromobutane an SN2 Reaction Introduction: In order to synthesize 1-Bromobutane an alkyl halide must be present to undergo a nucleophilic substitution reaction of an alcohol. Since 1-butanol is a primary substrate it will undergo an SN2 reaction with sodium bromide in order to convert the alcohol group to water which is a better leaving group and will in the end produce 1-bromobutane. Experimentally

aMicroscale Synthesis of Isopentyl Acetate (Banana Oil) Objective: Carried out the microscale synthesis of isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. This was an acid catalyzed Fischer esterification. Both extraction and distillation were employed to obtain a pure product. IR spectroscopy and gas chromatography were used to determine purity of the final product. Reagents: * Compound: | * MW (g/mol): | * MP (°C): | * BP (°C): | * Density (g/mL):

Synthesis Conclusion: Conclusion: As we can see‚ the sources show us that during the Enlightenment period money was very important. It shows that during the time people would do merely anything for money‚ even force their children into arranged marriages or‚ as Voltaire suggest satirically‚ sell them as a food source. Parents or even the brides and grooms themselves would arranged marriages for economic gain. This was not always the case. We have learned from She Stoops to Conquer that‚ although

In part A‚ solutions needed in the experiment were prepared‚ and the LabQuest was set up. By adding 100mL 6M HCl to 200mL deionized water‚ 300mL of 2M HCl solution was prepared. Then 150mL 2M NaOH solution was prepared by adding 100mL 3M NaOH to 50mL deionized water. Finally‚ the LabQuest was connected to the temperature probe‚ and set up to collect data every 15 seconds‚ the duration was set to be 180 seconds. In part B‚ three reactions were performed. In reaction 1‚ two Styrofoam cups were stacked

PRODUCTION OF CITRIC ACID Introduction: Citric acid is a White solid‚C3H4OH(COOH)3‚soluble in water and slightly soluble in organic solvents‚ which melts at 153 oC. Aqueous solutions of citric acid are slightly more acidic than solutions of acetic acid. Traces of citric acid are found in numerous plants and animals‚ because it is a nearly universal intermediate product of metabolism. Large amount of the acid are found in the juice of citrus fruits‚ from which it is precipitated by the

Many people are split on ideas as to what is causing this health crisis. “Don’t Blame the Eater” by David Zinczenko‚ and “What You Eat Is Your Business” by Radley Balko are two essays that discuss problems with the current system as well as potential solutions to these problems. While Zinczenko argues that the problem is coming from a lack of information on the products being consumed
