I really need help figuring out the theoretic yield for the acetaminophen lab in organic chemistry i haven't done this in a while and completely forgot how to do this the starting materials are 0400 g of p-aminophen molecular weight=1091, 12 ml water, and 0450 ml acetic anhydride molecular weight = 1021 please explain how do figure this out, any help is appreciated. In this investigation, the synthesis of acetaminophen was attempted using a three step experiment in lab within timeframe of experiment and because of the structural similarities to p­aminophenol upon completion of the selective acylation, acetanilide was created an ir spectroscopy was. The acetaminophen yield was 096, and a melting point was performed on the pure acetaminophen and was compared it to the literature value the melting point produced was 1678-1766, while the literature value was 169 - 1705.

Esterification reaction: the synthesis and purification of 2-acetoxybenzoic acid and subsequent analysis of the pure product (acetylsalicylic acid ) via thin-layer chromatography. A sequence suitable for the undergraduate and high school laboratory has been developed for the synthesis of the sweetener dulcin from the analgesic acetaminophen. Caproic acid synthesis essay 1648 words | 7 pages introduction in this 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. Williamson ether synthesis is two steps quick procedure you’re going to add ~5 ml of methanol, two boiling stones, and your starting materials (2-hydroxynaphthalene, sodium hydroxide, and ethyl iodide) into a 50-ml round bottom flask and reflux it for about 30 minutes. Acetaminophen and convert it into phenacetin, another pain reliever phenacetin was banned by the food and drug admininstration (fda) in 1983 due to adverse side effects including increased risk of certain cancers and kidney damage.

Qualitative analysis of aspirin and acetaminophen in a sample background [prelab assignment (40 points) due at the begining of lab] this laboratory activity is based on investigation 9 in your ap chemistry lab manual thus, it provides some relevant background for the following prelab questions and this laboratory activity. Acetaminophen lab essaysthe purpose of this lab was to use our techniques that we have learned so far in lab in order to synthesize acetaminophen from p-aminophenol and acetic anhydride this lab was also intended to teach us how to isolate and recrystallize our compound in order to get rid of as mu. The test for acetaminophen is used to measure the level of drug in the blood in order to establish a diagnosis of overdosage, to assess the risk of liver damage, and to help decide on the need for treatment. When the phase 2 pathways of acetaminophen toxicity get saturated, acetaminophen will then get metabolized via the phase 1 pathway, cyp2e1, in the liver and a small amount in the kidneys to generate the toxic metabolite napqi (n-acetyl-p-benzoquinonimine.
