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

of 86.9%). The percent yield after recrystallization‚ was 80.9%. INTRODUCTION The goal of this experiment was the synthesis of 3-nitrochalcone from 3-nitrobenzaldehyde and acetophenone as shown in Figure 1: Figure 1: Synthesis of 3-Nitrochalcone from 3-Nitrobenzaldehyde and Acetophenone Source: cnx.org The mechanism for the synthesis of 3-nitrochalcone is presented in Figure 2. The alpha carbon on the acetophenone is deprotonated‚ followed by the attack of the alpha carbon anion on the carbonyl

Scuba diving is a form of underwater diving in which a diver uses a scuba set to breathe underwater. According to the Professional Association of Diving Instructor (PADI)‚ a “DEEP DIVE” is considered to be anything from 18 meters (60 ft) to 30 meters (100 ft). A scuba diver moves around underwater by using swim-fins attached to the feet‚ however external propulsion can be provided by a diver propulsion vehicle. Scuba diving may be performed for a number of reasons; either for recreational purposes

Polymer Chemistry Classification of Polymers – Notes prepared by The most common way of classifying polymers is to separate them into three groups - thermoplastics‚ thermosets‚ and elastomers5. The thermoplastics can be divided into two types - those that are crystalline and those that are amorphous. You may click on the words in the diagram below to learn more about these classifications. Thermoplastics Molecules in a thermoplastic are held together by relatively weak intermolecular

Yield Data The reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting

Explanatory Synthesis A countless number of children in the United States were taught to believe that you could accomplish anything if you worked hard. This American dream has now become an American nightmare. According to the information in the Hart Research Associations titled “Raising the Bar‚” “ How the Rich are getting Richer and Poor are getting Poorer‚” and the Workforce Commission powerpoint‚ Americans are faced with many obstacles to learn how to survive in the economy.

Chemistry 12 Unit 1 - Reaction Kinetics Chemistry 12 Worksheet 1-3 - Reaction Mechanisms 1. It is known that compounds called chlorofluorocarbons (C.F.C.s) (eg. CFCl3) will break up in the presence of ultraviolet radiation‚ such as found in the upper atmosphere‚ forming single chlorine atoms: CFCl3 CFCl2 + Cl The Cl atoms then react with Ozone (O3) as outlined in the following mechanism. Step 1: Step 2: Cl + O3 ClO + O2 ClO + O Cl + O2 (single "O" atoms occur naturally in the atmosphere
