Among them were dehydration‚ isolation‚ drying‚ and distillation. We used all of these techniques to get the product we were looking for. In addition to these experimental techniques we also verified our product via spectroscopy which is a new technique. Using IR spectroscopy we were able to specifically analyze the functional groups on our product. Results and Discussions: Reaction Equation: Theoretical Yields: Based on limiting moles of product -Based on C7H14O 24 mL C7H14O

Identification of Unknown Organic Compound by Melting Point (M.P)‚ Boiling Point (B.P) and Infrared Spectroscopy Methods and Background The main objective of this lab is to identify the given unknown organic compounds with various methods. Identification of an unknown compound is important to perform through the process of melting point (M.P)‚ boiling point (B.P) and Infrared spectroscopy (I.R).

concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water‚ then dried with anhydrous sodium sulfate. The product was then distilled using a Hickman still and characterized using infrared spectroscopy. The percent yield of isopentyl acetate was 61.52%. This may have been low due to not all of the condensed product being removed from the Hickman still‚ some product being lost during transfer of the product from the reaction tube into the Hickman

Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted

Alkene Synthesis from Alcohol: Preparation of Cyclohexene From Cyclohexanol 5/29/14 Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized

Nolan 14832679 Introduction 4-hydroxy-3-methoxybenzaldehyde or as it is better known‚ vanillin is most commonly used to create imitation vanilla essence (Southam‚ 2013). Figure 1: vanillin structure Vanillin was first synthesised from eugenol from 1874 – 2001‚ from where it was later made from lignin- containing sulphite liquor which is a by-product of wood pulp processing in paper pulp manufacturing‚ most recently it is more common to find vanillin made from guaiacol and glyoxlic acid

First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment began‚ or was it found based on a similarly known variable so the epsilon value could be known for Beer’s law. Additionally‚
