from natural sources tend to have impurities. One way for us to remove these impurities and obtain our desired product is by using a technique called recrystallization. Our goal in this experiment is to prove that recrystallization is a method to purify a solid organic compound with contaminants. In Part A we will purify acetanilide by recrystallization and in Part B we will distinguish the best way to select the solvent required to recrystallize the solute. Removing the solid impurities of an organic

this experiment, the objective is to perform recrystallization properly to purify multiple organic solids. Recrystallization has become a fundamental technique in organic chemistry and the pharmaceutical industry, for separating and purifying organic compounds. Out of all the techniques used for purifying organic compounds, recrystallization is the most vital one. This is due to its effectiveness, convenience, and industrial applications. Recrystallization has to do with dissolving organic compounds

Experiment #1: INTRODUCTION 1. List the basic steps in the recrystallization of acetanilide. Include the identity of the solvent that will be used and what is added before hot filtration. a. Dissolving the Sample: Begin by using 35 mL of water as the solvent. Then dissolving 2g of crude acetanilide, bringing the solution to a boil and stirring it with a glass rod. Once dissolved, slowly add a dash of activated charcoal to the non-boiling solution. Begin to boil the solution a second time. b. Hot

The Recrystallization of Benzoic Acid through solubility and filtration. Summary: An ideal solvent of 95% Ethanol was determined from the given solvents of water, 95% ethanol and hexane. Once the ideal solvent was determined a recovery of 27% or 0.54 grams of Benzoic Acid from 2.0 grams of crude Benzoic Acid mix using the 95% ethanol. The product was a white crystalline solid that produced a melting point range of 116-120 C compared to the actual range of 121-123 C meaning that a small amount of

L Section: 006 Lab Partner: Jake Bodway TA: Benjamin Pollard Experiment 4: Recrystallization of Pure Phthalic Acid, Benzoic Acid and Naphthalene Introduction Section Recrystallization is a technique frequently used in organic chemistry to purify solid organic compounds. The goal of this technique is to allow organic compounds to form crystal lattice structures, and to remove any of the impurities that do not align within this crystal structure.1 The theory behind recrystallization revolves around

goal for recrystallizing crude cinnamic acid was to purify the acid and filter out any impurities. Recrystallization is one method used to purify a compound. Using a hot solvent, the compound is dissolved. It is then cooled to produce pure crystals. “As the crystal develops, impurities are excluded from the crystal lattice, thereby completing the purification process.”1 The key to recrystallization is the solvent used. “The solute must be relatively insoluble in the solvent at room temperature but

Experiment 4: Recrystallization of Pure Phthalic Acid, Benzoic Acid, and Naphthalene Charles Nyberg Gilbert Immanuel and Rachel Zigelsky Mussie Gide   Introduction Chemical experiments are often described, when they are finished, by the yield or recovery of the target product or solid. Also melting point can be tested to determine purity in a compound. Most times these chemicals are not completely pure so they can be recrystallized to remove the impurities. The technique of recrystallization learned and

Aneri Patel CHEM 2100 Midterm Lab Report Fall 2017 Comar Unknown Number #####  Introduction: The main purpose of these experiments was introduce various techniques such as the use of separation, purification and extraction for each organic compound that was obtained. The first experiment was done on a compound which is commonly known as a triglyceride which contains three fatty acids and a glycerol backbone. The next experiment was done one a caffeine which is a hetercylic ring. However, this heterocyclic

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
