lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic acid derived from

Synthesis of benzilic acid from benzoin utilizing a multi-step reaction. Names: Arian Karim TA Name: Sayantan Das Lab Day & Time: Thursday 7:30-11:40 Lab Section #: Abstract The main purpose of this experiment was to synthesize benzilic acid from benzoin. This requires a multistep synthesis with benzyl as an intermediate product. The first step required HNO3 as an oxidizing agent and the second step required KOH and HCl. The percentage yields of benzil and benzilic acid were 59.5%

purpose of this experiment is to synthesize methyl nitrobenzoate from methyl benzoate‚ concentrated HNO3‚ and concentrated H2SO4 via an electrophilic aromatic substitution reaction. Reaction Procedures/ Observations Use a 50 ml beaker to cool about 6 ml of concentrated sulfuric acid in an ice water bath. Weigh the vial containing about 3 grams of methyl benzoate and add it to the cooled sulfuric acid. Next pour about 2 ml of sulfuric acid to the nitric acid in the vial and allow for it to cool

The Grignard Synthesis of 3-methyl-3-heptanol In this experiment‚ an example of an organometallic compound which has a carbon magnesium bond will be utilized to form a tertiary alcohol. Grignard reagents have been extremely useful in the synthesis of a large number of classes of organic functional groups. Although Grignard reagents are unstable and decompose in air and moisture‚ they can be prepared and used immediately with moderate difficulty in the undergraduate organic chemistry laboratory

Experiment #5: Esterification of Methyl Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol

Synthesis and Purification of Acetylsalicylic Acid (ASA or Aspirin) Background Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions‚ creating an ester either with the hydroxyl or with the acid. In the presence of acetic anhydride‚ acetylsalicylic acid (aspirin or ASA) is formed. Correspondingly‚ an excess of methanol will form methyl salicylate‚ which is also an analgesic. In this experiment‚ we shall use
Free Aspirin Acetic acid Carboxylic acid
Acetylsalicylic acid is the active pharmaceutical ingredient in aspirin and can be synthesized by the esterification reaction of salicylic acid and acetic anhydride in the presence of an acid catalyst. An esterification reaction is when an acid is converted into an ester by combining with an alcohol and removing a water molecule. When heating the salicylic acid mixture in the warm water bath‚ the mixture should be removed from the bath within 8 minutes‚ to reduce the chance of the acetylsalicylic acid decomposing
