Abstract This paper describes the process of determining an unknown isomer of nitroacetanilide over a two-week process. The first step was synthesizing acetanilide from aniline and acetic anhydride. The resulting acetanilide product yield was 11.01 grams, giving a percent yield of 76.99%. Once this was achieved and verified through melting point, IR, and NMR tests, with a melting point range of 112° - 115.5° C. The acetanilide underwent nitration to form nitroacetanilide. The resulting nitroacetanilide

4.2.4.1 Synthesis of iminodi(N-benzylacetamide) A solution of a mixture of diethyl iminodiacetate (3.0 g, 15.8 mmol) and benzylamine (6.8 g, 63.2 mmol) was kept at reflux for 12 h [142]，and then cooled to room temperature. The precipitated crystals were filtered off, and gave white solid of iminodi(N-benzylacetamide). Yield: 91.2 %, M.p.: 116–118°C. 1H NMR (DMSO-d6, 400 MHz): δ = 7.089 (s, 2H, O=C-NH), 3.267-3.076 (m, 4H, N-CH2), 3.061-3.030 (d, 4H, O=C-CH2), 2.339 (s, 1H, NH), 1.815-1.740 (m, 2H

Experiments 4A-C: Synthesis and Component Analysis of an Iron (III) Oxalate Complex My Name TA, Section B## Work Performed on 10/23, 10/30, & 11/4, 200# Report due Tuesday, November ##, 200# 1. Abstract This experiment initially involved the synthesis of an iron (III) oxalate complex with the general formula Kw[Fex(C2O4)y]·zH2O. The variables x, y, and z were determined through the duration of the entire experiment. From 1.2000g of Fe(NH4)2(SO4)2 were synthesized 1.1###g of K3[FeIII(C2O4)3]·3H2O

LABORATORY REPORT 4 PREPARATION OF ALUM FROM ALUMINUM METAL Huy Nguyen October 2nd, 2012 The objective of the laboratory is to synthesize alum (KAl(SO4)2.xH2O) from aluminum powder and to determine the proportion of water in the alum crystals. Alum is a product from the reaction between potassium hydroxide and sulfuric acid. The reaction include several steps, as followed: Aluminum powder reacts with potassium hydroxide to generate Al(OH)4- ions and release hydrogen. 2 Al(s) + 2 KOH(aq)

11/17/2011 The Preparation of Calcium Carbonate Purpose: To create chalk (calcium carbonate) and to find the percentage yield in order to see the amounts of anhydrous sodium carbonate and calcium chloride were used up. Also to see if there’s any alterations like mass differentials. Objectives: 1. To introduce the concept of “limiting factor” in a chemical reaction 2. To practice a. Writing a balanced equation b. Determining the number of moles of each reactant and product

Copper in Silver Nitrate Lab: Making Silver Sabrina Kate S. Carranza – Chemistry Hour 6 I. Purpose: The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors. II. Hypothesis: /3 -If the copper metal is submerged in the silver nitrate solution

Title: Alum synthesis Author Information: Alexis Luevano-Yatarola*, Francine Herreros, Chemistry 111/112, section 531 Introduction: In today’s society the amount of Aluminum consumed is not completely recognized most of society only tends to think of aluminum cans, however aluminum is in a wide range of everyday products such as car parts, jets, and in household products in which we use everyday. Due to the large amounts of aluminum used and consumed daily recycling the material is a very important

The Viability of Recycling Aluminum Seth Smith*, David Fahey, Experiment 4, CHEM 111-520 Introduction In this experiment, metathesis, redox, single displacement, and decomposition reactions were observed and recorded to follow the path of recycled aluminum. The percent yield of the aluminum was also calculated to compare the actual yield with the theoretical yield. The entire concept of aluminum recycling was also observed and successfully reproduced. Materials and Methods The experiment began

Experiment 8: Phenol Alkylation Amber Chavis CHEM 2753 - 007 November 15, 2017 Objective/Purpose: This experiment was designed by conducting a substitution reaction to construct a complex compound (2-methylphenoxyacetic acid) from two simple parts; also known as synthesis - converting simple molecules into more complex molecules. A purification technique known as crystallization was used to purify the product. Suction filtration was used to filter out the product. The experiment was completed over
