Dibenzalacetone Synthesis Report

Decent Essays
Abstract: Dibenzalacetone was synthesized with 5.772 g of pure product recovered. It was equivalent to 82% total yield and 65.99% recover from the crude product. Cis-trans and trans-trans isomers of dibenzalacetone were confirmed to be in the product by Infrared spectrum and melting point analysis. Although 2 isomers were existed, trans-trans was confirmed to be the major product due to its stability.

Statement and purpose
Dibenzalacetone was synthesized by Aldol condensation method.
Introduction
Aldol condensation is the based catalyzed reaction of an aldehyde that does not have alpha carbon with ketone that does. In this experiment, Acetone, which has 2 alpha carbons, was used to react with 2 moles of benzaldehyde, which has no alpha

    The goal of experiment four was to use sodium dichromate to oxidize borneol to camphor. The camphor was purified using sublimation, then reduced to isomeric alcohol isoborneol with sodium borohydride. 1H NMR was used to determine the ratio of borneol to isoborneol in the final product. The experiment was carried out by using sodium dichromate to oxidize a borneol solution. Once the reaction was complete the mixture was separated using extraction techniques, dried, and ether was removed via the rotovap.…

    The citric acid cycle generates energy from the oxidation of various fuel molecules to acetyl coenzyme A (acetyl CoA). Acetyl CoA undergoes several redox, hydration and decarboxylation reactions to produce carbon dioxide (CO2), reduced nicotinamide adenine dinucleotide (NADH), reduced flavin adenine dinucleotide (FADH2), adenosine triphosphate (ATP) and hydrogen ions. The citric acid cycle links glycolysis which produces pyruvate from glucose and oxidative phosphorylation which generates ATP which is used as energy for metabolic processes. The citric acid cycle is catabolic and anabolic. Fuel molecules are catabolised (broken down) to generate ATP.…

    Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a couple preliminary tests, which include physical state and smell.…

    In this experiment, unknown B was a solid mixture containing two compounds of interests, 1,4-dimethoxybenzene and neutral benzoic acid. These compounds were separated by extraction and washing, and liquid-liquid extraction was specifically performed. Extraction is the process by which a compound of interest is selectively removed from impurities, and washing is the process by which unwanted products or impurities are selectively removed from the desired product. In liquid-liquid extraction, unknown B was dissolved sequentially into two immiscible liquids via a separatory funnel.…

    In this experiment, the competing enantioselective conversion (CEC) method was used to react an unknown secondary alcohol, which is either the R- or the S- enantiomer, with S-HBTM and R-HBTM separately. Thin-layer chromatography (TLC) was used to determine which reaction was faster. If the S-HBTM was faster, then the unknown secondary alcohol had the R configuration. If the R-HBTM was faster, then the unknown secondary alcohol had the S configuration. 1H NMR was used to determine the molecular structure of the unknown secondary alcohol.…

    The purpose of this experiment was to synthesize 9,10-dihydroanthracene-9,10-α,β- succinic anhydride by performing a Diels-Alder reaction of anthracene with maleic anhydride. This reaction can also be called a cycloaddition, because the diene, anthracene, is added to the an alkene, maleic anhydride, to produce a cyclic compound. Since anthracene is a cyclic diene, it also favors an endo product despite sterical hindrance. The Diels-Alder reaction is a very powerful reaction and useful in synthetic organic chemistry due to its good control over regio- and stereochemical properties.…

    This experiment encompasses the reduction of 2-methylcyclohexanon to 2-methylcyclohexanol. The borohydride reduction experiment aim to use sodium borohydride with methanol to reduce ketone into secondary alcohol. This reaction take advantage of the hydride ion in order to initiate a nucleophilic addition to the carbonyl group of the ketone. The common reactant that are used in reduction experiment in the lab are sodium borohydride and lithium aluminum. Those two reactants contain hydride anion that facilitate the nucleophilic addition.…

    This month I read the book The Compound by S.A Bodeen. This book was well written and fast paced, I like the suspense and the voice. I, however, thought that some of the plot points were a little predictable and at some points even drawn out. Overall I would rate this book an 8/10. In this book Eli and his family are forced into an underground bunker after a nuclear bomb leaves them shell-shocked and heartbroken.…

    Paracetamol is one of the world’s most beneficial and resourceful analgesic and is widely used in present day. An analgesic, can be defined, as a chemical compound that relieves pain, reduces fever and inflammation. It works by hindering the enzyme cyclooxygenase which acts a catalyst to convert fatty acids to prostaglandins. Prostaglandins cause pain and inflammation to peripheral and central points in the nervous system2. Paracetamol, or Acetaminophen is created by the synthesis and preparation of an amide.…

    Abstract: The objective of this experiment was to synthesize aspirin from salicylic acid and acetic anhydride. The general theory behind this experiment was to study the synthesis of a drug from organic materials. During the experiment, esterification had occurred between reactants salicylic acid and acetic anhydride. Then, phosphoric acid would catalyze the reaction and water would be added to decompose the remaining acetic anhydride. Through the process of filtration, aspirin crystals were collected and separate from the liquid acetic acid-water solution.…

    Benzocaine was synthesized from p-toluidine in a four step synthesis. Each intermediate product, including N-acetyl-p-toluidine, p-acetamidobenzoic acid, and p-aminobenzoic acid, was checked for yield, presence, and purity through weighing, taking IR and NMR spectrums, and determining the melting point. Thin Layer Chromatography was used to ensure the completion of the final reaction from p-aminobenzoic acid to benzocaine. The yield of the first step from p-toluidine to N-acetyl-p-toluidine was 91.9%. The yield of the second step from N-acetyl-p-toluidine to p-acetamidobenzoic acid was 49.85% The yield of the third step from p-acetamidobenzoic acid to p-aminobenzoic acid was 32.49%, which was not enough to continue so some product was borrowed…
