aldol condensation reaction.5 This product was obtained using extraction (reflux)‚ recrystallization and vacuum filtration to separate the product from the waste. Experiment Scheme: Figure 1: Experiment Reaction5 Figure 2: Step wise reaction mechanism including aldol condensation reaction5 Procedure: About 1.55-g of benzil‚ 1.51-g of dibenzylketone and 12-mL of ethanol were placed in a 50-mL round bottom flask. A magnetic stir bar was also placed in the flask. A condenser was attached to the

Reactions of Carbonyls-Aldehyde/Ketone Analysis: Introduction: The carbonyl group is a rich source of many important reactions in organic chemistry‚ with two fundamental properties that are primarily responsible for its diverse chemistry. The first is the polarization of the. Carbon-oxygen pi bond‚ owing to the relatively high electro negativity. The second property of a carbonyl function is to increase the acidity of the alpha-hydrogen atoms‚ which are the hydrogen’s

dichromate and 1 drop of concentrated sulfuric acid were added to 1-pentanol‚ the color of 1-pentaol turned into dark green. In second experiment‚ precipitation was found when 6 drops of 2‚4-dinitrophenylhydrazine were added to both 5 drops of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments is to find if one substance has alcohols‚ aldehydes or ketones. If one

gently into the solution. 3. Transfer the beaker from the ice bath onto the hot plate and measure the temperature of this solution to make sure it was still at or under 25 °C. 4. After letting the mixture stir for some time‚ prepare 5mL of benzaldehyde with 1.85mL of acetone into a 50mL Erlenmeyer Flask. 5. Transfer about half of the mixture into the stirring solution of NaOH‚ water and ethanol. After 2 -3 minutes‚ yellow cloudiness formed. After 10 minutes add the remainder of the solution

22-2-96 CONDUCTING POLYMERS By Colin Pratt INTRODUCTION Until about 30 years ago all carbon based polymers were rigidly regarded as insulators. The idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed‚ plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer known

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

It has been reported that TMA‚ benzaldehyde and 4 to 7 carbon chain acids are the most important contributors to the aroma of fish sauce. 3-Methylbutanal and 2-methylbutanal were also present at concentrations greater than their thresholds of 0.2 and 3 ppb‚ respectively [14‚15]‚ in addition 2-methyl and 3-methylbutanal‚ dimethyldisulfide and benzaldehyde were major aroma-active compounds. Thai fish sauce also has been

Rules for aromaticity 1. A cyclic planer structure and each atom must have a P orbital so that the electron cloud is not intterupted 2. It must contain an odd number of electron pairs ▪ i.e. the number of electrons must be 4n+2 where n=0‚1‚2‚3‚4……… ▪ so the number of electrons is 2‚6‚10‚14‚18……. ▪ this rule is called the Hückel’s Rule • monocyclic hydrocarbons with alternating single and double bonds are called annulenes • annulenes are named as [n]-annulene
