In our experiment, we were able to synthesize isopentyl acetate by heating a reaction mixture of isopentyl alcohol with excess acetic acid. We were then able to purify the isopentyl alcohol by using the methods of extraction, drying, and distillation. Our synthesis and purification of isopentyl acetate was fairly successful in allowing us to obtain and analyze banana oil. Questions 1. In addition to using excess acetic acid to form the ester, the reaction can also be influenced by removing water from the reaction mixture.
Distillation Distillation is used to remove impurities from a mixture – one component of which must be a liquid. Boiling points are utilized in determining the identity of the unknowns. Types of distillation include
Isopropanol is available in the market and is produced by the indirect hydration of propylene in a multistage process that offers very high product purity and consistent quality. The primary advantage of this process is that the acetone produced is free from trace aromatic compounds, particularly benzene as in the cumene route. Benzene forms explosive mixtures with air and is acutely toxic as well as brings harms to health. Cumene route to synthesis acetone produce ethanol as coproduct, the ethanol produced is a waste as the main product required is acetone. Besides, CHP produced from the oxidation of cumene is explosive and dangerous.
Aim The purpose of this experiment was to use fractional distillation technique to separate cyclohexane and toluene. Background Information Distillation is a technique which is used for separating two or more volatile products based on differences in their boiling points. Distillation can be used to separate a volatile solvent from a non-volatile product and separate a volatile product from non-volatile impurities. Simple distillation consists of a round-bottom flask, a distilling head, a condenser, an adapter and a receiver which are used to separate compounds where one is considerably more volatile than the other compound. This distillation is performed in one step.
Introduction The purpose of this experiment was to purify acetanilide that was contaminated with relatively small amounts of impurities using recrystallization. The success of recrystallization was dependent on a suitable solvent being chosen and proper recrystallization technique being carried out. The solvent chosen had to have a different polarity than that of the molecule of interest. The technique used was dependent on the solubility of the solvent at higher temperature and the solubility of the impurities at all temperatures. To analyze the acetanilide product of the reaction, 1H NMR and IR were used.
Experiment 4: Formal Report Preparation and Recrystallisation of Aspirin Aim of the experiment: In this experiment, a pure sample of aspirin is to be obtained through esterification to synthesise the sample, then purify the sample by recrystallisation. Lastly, determine the melting point of the sample to characterise the aspirin. Introduction: Background Aspirin (acetylsalicylic acid) is an aromatic compound that contains an ester- functional group and a carboxylic acid- functional group. Aspirin is commonly used as a pain reliever (analgesic), an anti-inflammatory, an anti-coagulant (prevent platelet aggregation) and an antipyretic (to reduce fever) pill. It helps to prevent strokes, heart attacks and blood clot formation.
Aspirin is synthesized through three different steps, the synthesis of the aspirin, the isolation and the purification and finally the purity estimation of the final product. It involves the reaction of acetic anhydride and salicylic acid in the presence of phosphoric acid = H3PO4. After the aspirin is synthesised it then mist be isolated form the reaction solution and purified. This procedure is a possible experiment to execute at a
Fractional distillation is a separation technique used to separate two liquids with different boiling points and keep the liquid. To do this, we set it up just like the distillation lab with the 10-15mL in the test tube over the fire and the tube leading the the test tube in the beaker. The first time you go through, the same test tube is left in the whole time but you must record the temperature around every 10-15 seconds using your labquest. You then find two places where the temperature is consistent for a few seconds, this is your plateau. The second time you go through, change out the test tubes as soon as you get to your first plateau, this liquid is liquid one.
REVIEW ON CONVERSION OF CO2 INTO NEW VALUABLE FORM R.W. GAIKWAD1- R. M. GHUGE2, Y. N. TANGADPALLE3 1 Prof., Department of chemical engineering, Pravara Rural Engineering College, Maharashtra, India 2Student, Department of chemical engineering, Pravara Rural Engineering College, Maharashtra, India 3 Student, Department of chemical engineering, Pravara Rural Engineering College, Maharashtra, India ABSTRACT Nature utilizes CO2 to produce countless substances that are consumed by humans as well as animals. Many industrial procedures aim to accelerate the utilization of CO2. There are mainly three pathways for using CO2 and namely they are conversion of CO2 to fuel, utilization of CO2 as a feedstock for chemicals and non-conversion use of CO2.  The technologies to moderate CO2 emissions are essential for the chemical industry to become “greener”.
