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 hyaluronic acid (HA) with glycidyl methacrylate (GM) is a strategy for producing photocross-linkable macromers to generate biodegradable hydrogels by in-situ injection and light-induced polymerization. Facile synthesis and characterization by 1H NMR spectroscopy of a series of photopolymerizable macromers based on HA-glycidyl methacrylate (HAGM) conjugates with various degrees of methacrylation (DM) ranging from 14% to 90% are described. Aqueous solutions of HAGM were photopolymerized to yield

group activities among students to build a natural setting for collaborative learning and reciprocal teaching. Mentoring high school and undergraduate students for interdisciplinary research projects ranging from bionanotechnology to applications of NMR in biophysics impressed upon me the value of cultivating independent thinking and the significance of designing a focused route to apply students’ skills and expand their knowledge. Most of my students‚ whom I mentored‚ are women and/or members of

Formulating Problem Statements: Using Audience Awareness to Contextualize Your Research Goals A persuasive problem statement consists of three parts: 1) the ideal‚ 2) the reality‚ and 3) the consequences for the reader of the feasibility report. Well constructed problem statements will convince your audience that the problem is real and worth having you investigate. Your strategy is one of contrast: by situating the the ideal scenario next to the situation as it exists‚ you can not only

Experiment C. Aim: To protect one of two carbonyl groups (C1) in order to allow the other to react twice with a Grignard followed by removal of the protecting group by acid hydrolysis to give final product (C2). Method: Ethyl acetoacetate (30.03g)‚ ethylene glycol (15.01g) and toluene-p-sulphonic acid (0.13g) were added to a 250 cm3 round bottomed flask‚ containing a stirrer bar and toluene (100 cm3)‚ fitted with a condenser and dean-stark head.

Synthesis and Isolation of Expectorant Guaifenesin By: Ben DuBose Dr. Cossey 3361L Abstract The purpose of this experiment was to isolate and synthesize Guaifenesin. Isolation was performed with the use of two Guai-Aid Tablets‚ each of which contained 400mg of pure Guaifenesin. Reflux‚ a technique used to heat a mixture without evaporating the solution‚ was used to synthesize Guaifenesin through a Williamson Ether Synthesis reaction with an SN2 mechanism. Introduction
