Synthesis of Acetaminophen Lab Report Bijal Patel, 20467049 Partner: Poojan Parikh T.A.’s: Long Pu CHEM 123L, Section: 006, Rm: ESC 149 Tuesday February 4, 2013, 2:30pm-5:20pm Experiment Done: Tuesday January 22, 2013 Introduction Acetaminophen was first introduced in 1955 (Richman, 2004). It is an over-the-counter drug that relieves pain and reduced fevers. Acetaminophen is considered an alternate to aspirin since it does not irritate the stomach (Richman, 2004). It also has very
tubes and a MelTemp device was used to measure the new melting point. A sample of crystals was run through the IR spectrometer to obtain the infrared spectra for the purified benzocaine product. The data and calculations sheets are attached to the report. Results and Discussion Ethyl p-aminobenzoate, or benzocaine, was synthesized via the esterification reaction mechanism of ¬¬p-aminobenzoic acid and ethanol in the presence of sulfuric acid. The mass of the crude benzocaine product was determined
University of Singapore CM1501 Organic Chemistry for Engineers Lab Report Experiment 2: Separation and Identification of Two Organic Compounds 10th October 2013 Abstract This experiment involves the separation and identification of 2 organic compounds (1 Neutral Compound and 1 Acidic Compound) in a mixture. Separation techniques used in this experiment include solvent extraction, simple distillation and recrystallization using a suitable solvent determined through a solubility test. The
CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances, it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive, or independent
Learning Activity 1 Preparation of Acetanilide Abstract Recrystallization is a common method of purifying organic substances through the difference in solubility at different temperature. In this experiment, acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution, molecules of other compounds

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion, which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product, and the melting point of the possible results were 59 °C for 1-nitronaphthalene, and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated
Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds, one solid and one liquid, from an ethereal solution using the techniques of chemically active extraction, vacuum filtration, simple distillation, and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges, and analyzing IR and proton/carbon NMR spectrums It was determined
