Acid-base extraction

In experiment 2, we used liquid-liquid extraction to separate a mixture using two immiscible solvents. We made use of extraction, back extraction, neutralization, and melting point technique to figure out the identity of the acid, base and neutral from the combined unknown mixture. There were a couple things that we had to pay close attention to. For example, identifying the organic and aqueous layer as liquid-liquid extraction is usually used to separate organic product from the mixing with the

Physical Properties and Structures of the Reactants and Products in the Experiment Dichloromethane Dichloromethane has a

lab was to learn how to perform liquid-liquid extraction in order to isolate benzocaine and benzoic acid from a mixture. The initial mass of the impure mixture of benzoic acid and benzocaine was 2.143 g. At the end of the experiment, 0.244 g of benzocaine was obtained, and 0.411 g of the benzoic acid was obtained. The melting point range for the benzocaine was 88.6 degrees Celsius to 90.4 degrees Celsius. The melting point range for the benzoic acid was 122.3 degrees Celsius to 125.6 degrees Celsius

Introduction Determining the identity of unknown compounds in a given solution is an important skill to have. This can be done through a series of steps including extraction, purification, and spectroscopic methods.1 Chemically active extraction uses the properties of the acid or base to remove it from the solution. The extraction process involves taking the solution, unknown compounds dissolved in organic solvent, and adding basic/acidic solutions to separate the unknown compounds.2 If adding

Hussain SCC 251 Organic Chemistry II Experiment 1: Separation of a Carboxylic acid, phenol and a neutral compound by Extraction Abstract: Extraction involves dissolving one or more compounds from a solid to a solvent or from a solution into another solvent. Extraction can be used to isolate an organic compound from a mixture or solution. The most common solvent used is 1-mthoxy-2-metylpropane and water. Extraction requires you to mix the solvent in a substance that is more soluble than the solvent

CONCLUSION The goal of the experiment was to use extraction to separate and identify the components of a mixture of acid, base, and neutral. This was completed, identifying the components to be benzoic acid (36.4% yield), meta-nitroaniline (52.7% yield), and naphthalene (52.7% yield). These identities were confirmed after separation and isolation using melting point analysis. The melting point observed for the benzoic acid was 121.2-122.5ºC, the meta-nitroaniline’s was 111.5-112.8ºC, and the neutral

Materials:Benzoic acid,p-dichlorobenzene,ether,10% NaOH,conc.HCl,distilled water, anhydrous CaCl2. Introduction: Organic compounds in an aqueous mixture can be separated

For this experiment, an organometallic reagent was used for the synthesis and isolation of benzoic acid. The Grignard reaction is the addition reaction of an organometallic reagent, which in this case was an organomagnesium reagent. An organometallic reagent is a carbon bonded to a metal. This reagent was combined with an electrophile, a carbonyl compound such as a ketone or aldehyde. Carbons are electrophilic when bound to a nonmetal thus the atoms are more electronegative than the carbon and metals

The chief strategy for most algal biodiesel makers is to isolate the algal species that have a high oil content, that will also grow rapidly to make biodiesel, biocrude and drop-in fuels. Algae with high oil content such as Botryococcus braunii (Bb) grow gradually and can be harvested only limited times throughout a week, whereas algae with lesser oil content such as Dunaliella or Nannochloropsis (about 30% range) will develop more rapidly and can be harvested daily or even a few times a day. For
