The Cyclohexanol Cycle and Nylon Synthesis Samantha Stuckey CHE 233L Section 302 Department of Chemistry‚ DePaul University‚ 1110 W. Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination

You are probably wondering what this table of colourful boxes is? Well you’ve come to the right place‚ I hope. What is it? Well everything in the world is made up of elements‚ well almost everything‚ light‚ heat‚ this is energy‚ another story. And elements are a single type of atom‚ the periodic table is basically a table of all know elements to man. What’s in it? To understand what’s in it we need to look at an atom and it subatomic parts. An atom is made up of an Electron(e-) this has a negative

1 CHAPTER 1 PROJECT BACKGROUND 1.0 PROJECT BACKGROUND The main objective is to design an economic Acrylonitrile chemical plant with safer ways of processes for a minimum production rate of 100‚ 000 metric tonnes/year. 1.1 INTRODUCTION Recently‚ production of acrylonitrile has been increasing every year in many countries. The rapid growth of the industry is mainly attributed to the availability of oil and gas as feedstock‚ a well-developed infrastructure‚ and a strong base

Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic acid as our acid catalyst which would be protonating the hydroxyl group of our butanol‚ to make a better leaving group‚ so that the bromine radical would be able to attack the leftover carbocation. Our group used 2-bromobutanol and we expected‚ from our mechanism‚ to achieve 2-bromobutane and when we compared our GC results to the prepared sample‚ our mechanism proved to be true. We did

In order to first perform the reaction‚ 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then‚ 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head‚ water condenser and a drying tube packed with calcium chloride to

But before going deeper on what these tests are‚ what first are the difference between their results which are the primary‚ secondary and the tertiary alcohols‚ aldehydes and ketones? Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Note however that there are different kinds of alcohols and Alcohols are categorized into different classes depending on how the -OH group is
