Green Oxidation of Menthol Enantiomers and Analysis by Circular Dichroism Spectroscopy by: Rita L. Wheeler A green oxidation of (-)-menthol to (-)-menthone was achieved through use of calcium hypochlorite. While many oxidation reagents are detrimental to the environment or expensive to acquire, calcium hypochlorite is cheap, produces little waste and facilitates a good yield of product. IR, CD, and NMR spectroscopic methods were used to confirm the identity and purity of the product. The final percent yield for the reaction […]
Purpose: Recrystallization To obtain a pure unknown sample by the means of recrystallization To calculate percent recovery through recrystallization Melting Point To identify an unknown by mixed melting point with at least two known compounds To identify at least two students having the same unknown Table of Reagents: Procedure: Exp 1A Recrystallization Pre-heat a large volume of water to 85-90°C Obtain solid unknown from TA. Record code number. Weigh ~2.00g, retain a very small portion for use as […]
A Qualitative Analysis of Two Organic Unknowns: Structural Elucidation and Subsequent Compound Derivation via the Direct Observation of Chemical, Physical, and Spectroscopic Molecular Properties Introduction The characterization and classification of an unknown organic compound (or multiple compounds) is a frequently implemented lab testing the cumulative skills of undergraduate students or lab novices at various Universities and related institutions. Moreover, necessitating students to apply various techniques learned throughout the lab course exhibiting individually varying degrees of retention in us of […]
Investigating Substitution Reactions of Various Alcohol-Containing Compounds Kristen Powell, Morgan Sanders, Robert Walker Department of Chemistry and Chemical Biology, IUPUI, 402 N. Blackford St., Indianapolis, IN 46202 This is a Laboratory Journal of Organic Chemistry Note for synthesis reaction data obtained in the Organic Chemistry Laboratory—All information was experimentally conducted. This article should be used as a reference when conducting your own synthesis reactions. Three reactions containing alcohol groups, on primary and secondary carbons reacting with halide groups have been […]
By: Omish Samaroo Introduction The purpose of this lab is as follows: 1) to learn about coordination compounds through the synthesis and analysis of a potassium ferrioxalate hydrate salt and 2) to use the techniques developed in previous labs to determine the empirical formula of the ferrioxalate salt. The ferrioxalate salt has the empirical formula Kx[Fey(C2O4)z]•nH2O. The values of x, y, z, and n are ascertained through determining the percentages of K, Fe, C2O42-, and H2O; converting these percentages to […]
By: Ciaran Forde and Catherine Garbutt ABSTRACT: All projects must be accompanied by an abstract. The abstract should briefly state the problem or purpose of the research, indicate the theoretical or experimental plan used, summarize the principal findings, and point out the major conclusions. Abstract length is one paragraph. INTRODUCTION: RESULTS & DISCUSSION: After analysis of the chromatograms obtained in the separation of solutions AP and PC we decided that the 70% pH 3.5 buffer with 30% methanol gave the […]
