Synthesis of and Fabric Test for Methyl Orange, and an Investigation of Acid-Base Properties of Textile Dyes By: Nick Fastuca Abstract: The azo-dye methyl orange was synthesized in two steps from sulfanilic acid and n,n-dimethylaniline with 52% yield. The reaction product was purified by recrystallization with water as the solvent. The synthesized methyl orange was tested to see how well it dyed 13 different kinds of fabric using a piece of Multifiber #43 cloth. The dye bound most strongly to wool […]
ANALYTICAL TECHNIQUES FOR THE COMPOSITION OF PETROLEUM ETHER FRACTIONS By: Mohammad Ali Salik AIM: The aim of this case study is to choose a suitable instrumental analytical method to investigate the composition of the different petroleum ether fractions. When choosing the analytical technique, a lot of factors need to be looked at such as cost, sensitivity (level of detection), resolution and availability of instrumentation. INTRODUCTION: Petroleum ethers are laboratory solvents which basically contain a mixture of alkanes – both branched and […]
The Wittig Reaction – Formal Report By: Alexander Davies Introduction Alkenes are important initial building blocks in many organic synthesis routes, as shown by Scheme 1.1 It is paramount, therefore, that we have the ability to synthesize alkenes from other readily available, cheap material. Scheme 1: Examples of one-step reactions from an alkene starting material. This illustrates the huge diversity of olefin products; and as such the need to be stereoselective in how one can synthesise said functionality within a molecule. […]
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 grams and then […]
The Dehydration of Alcohols By: Julia Trimble Introduction: Alcohols are organic compounds that derive from hydrocarbons that have replaced hydrogen with a hydroxyl group; the presence of a hydroxyl group is the primary signifier of this functional group.2 Given their structure, alcohols are capable of reacting with acids to create a more stable compound by cleaving the –OH group to make water.3 If a simple alcohol such as cyclohexanol were mixed with a strong acid like H2SO4 , the free H+ […]
Organometallic Chemistry and IR Spectroscopy – Synthesis of Molybdenum Carbonyl Complexes in a Microwave oven and Isomeric Phosphine Complexes By: Ansar Kapyatov Abstract [Mo(CO)4(NHC5H10)2] complex was prepared using a microwave synthesis method. Then Cis and Trans isomers of [Mo(CO)4(PPh3)2] were prepared and identified using IR spectroscopy and group theory analysis. Introduction This experiment is concerned with the study of some organometallic complexes, their thermodynamic stabilities and identification of their isomers. The actual preparation of our organometallic complexes deserves little attention seeing […]
