On a large scale ethanol and ethanoic acid is added to get the product ethyl ethanoate and water.

Reaction 2 - 1.Used a Beral- type pipet, added about 2mL (40 Drops) of 1M hydrochloric acid solution to a small test tube.

When the tip of the rod touched the pH paper, the color of the pH paper became blue.

Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction, solubility, crystallization and vacuum filtration. The experiment was carried out two times, both of which were successful.

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

As the first written assignment (due January 22, 2016) for the Junior Chemical Engineering Lab (CHE 352) taught by Professor Burrows, I will be endeavoring to provide a superior reflection of my personal standards and assignment quality. Although this assignment will be submitted to Professor Burrows, the individual that this assignment will benefit the most is me. This work will allow me to focus on data research, data analysis, professional writing skills, and advance my knowledge concerning the technical requirements of this course; thus, directing me towards a higher level of professional document writing and presentation. Through completion of this assignment, the guidelines of Professor Burrows will prepare me intellectually for the challenges of future written projects in this course, thus making my material easier to read and evaluate.

A strong desire to achieve my aspiration coupled with my interest in science field enabled me to secure admission in undergraduate program in science (Chemistry) from Mithibai College in Mumbai University, which is one of the top ten colleges in Mumbai, India. My genuine interest in chemistry brought me an award in "Srujan" project (Neutron Activation Analysis) associated with Nehru Science Center. The project edified my mind with practical knowledge and expertise in TLC, Crystallization, NMR, Spectroscopy (UV, Visible and IR), Chromatography (HPLC and Gas) and stereochemistry.

Subsequently, 10mL of 3.5% H2O2 were added dropwise to the reaction mixture and was stirred for 20 minutes before heating to boiling at 80°C for 5 minutes. The reaction mixture was then taken off heat and allowed to cool undisturbed in an ice-bath for 30 minutes. Suction filtration was performed after to collect the crystals from the chilled solution The product was then washed with chilled 95% ethanol (2 x 15mL) and followed by diethyl ether (2 x 10mL). The crude product was then left to dry before recording the yield. 20mg of the crude product is then accurately weighed out and dissolved in deionized water in a 25mL volumetric flask. Deionized water was added to the volumetric flask to the mark and the UV-vis absorption spectrum of the crude product was recorded.
