Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted

Experiment 11: Synthesis of Dibenzalacetone by the Aldol condensation Introduction: The Aldol condensation reaction‚ under basic conditions‚ involves the nucleophilic addition of an enolate ion to another carbonyl group. The resulting product‚ a beta-hydroxy ketone or aldehyde‚ is called an aldol because it contains both and aldehyde group and the hydroxy group of alcohol. Condensations‚ including aldol condensation‚ combine two or more molecules‚ typically with a loss of a smaller molecule (including

Aldol Condensation Discussion: 1. Aldol condensation reactions take place in basic conditions‚ where a deprotonated enol becomes an enolate and proceeds to attack the aldehyde. Since the solution is basic‚ it is able to deprotonate the alpha carbons of the product‚ which forces the hydroxide groups to leave. The product is then considered to be dehydrated and unsaturated. In terms of our reaction‚ cyclopentatone is deprotonated to form an enolate‚ which then attacks the two molecules of p-tolualdehyde
Premium Aldehyde Carbonyl Aldol condensation
Aldol Condensation Formal Abstract: An aldol condensation reaction was performed on acetophenone using p-anisaldehyde and sodium hydroxide as a base. This produced trans-p-anisalacetophenone in the form of a fluffy yellow crystal. The reaction was performed in a test tube and sodium hydroxide was added drop by drop followed by recrystallization and vacuum filtration. In order to verify the presence of the ketone 2‚4-dinitrophenylhydrazone was synthesized and reacted with trans-p-anisalacetophenone

5.1 MANUFACTURING PROCESSES: Acetone is produced directly or indirectly by propylene. Early processes for the manufacture of acetone were based on the thermal decomposition of calcium acetate or the carbohydrate fermentation of corn starch or molasses. The ready availability of propylene in the 1960s led to routes based on the dehydrogenation of isopropyl alcohol or cumene peroxidation. (1) By Cumene Oxidation (Hock Process). Propene is added to benzene [71-43-2] to form cumene [98-82-8]‚ which

Estimation of the Activation Energy for the Iodination of Acetone Through the Effect of Temperature on the Rate Constant Joel Costa‚ Alex Fuentes‚ Michael Chea‚ Rex Nwerem Dr. Morgan Ferguson July 9‚ 2013 ABSTRACT | It is often important to determine the rate at which a chemical reaction takes place‚ i.e.‚ how fast it yields the desired products. Temperature is one of the factors that influence the rate of reactions and it does so by providing energy to reactant particles so that a larger
