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

Structural Effects on Stability and Reactivity. Organic Chemstry Laboratory Structural Effects on Stability and Reactivity Introduction The concepts of stability and reactivity are fundamental to understanding chemistry. In this chapter we consider first the thermodynamic definition of chemical stability. We then consider chemical kinetics (Section 3.2) and how it can provide information about reactivity. We also explore how structure influences stability and reactivity. We want to learn how

Physics 4052 Spring 2004 Y. Kubota K. Wick Project Proposal for Physics 4052 Introduction You must begin to think about a possible experimental project to carry out next semester (Physics 4052). The reason for this is two-fold: first‚ it will introduce you to the process of proposal writing‚ which is an unavoidable and very important part of modern experimentation‚ and second‚ it will enable us to make any necessary plans for procuring equipment. To start you thinking about this process‚

chemical analysis of volatile oil and oleoresins were undertaken by gas chromatography-mass spectrometry (GC-MS) technique. GC-MS analysis of cinnamomum leaf volatile oil showed the presence 81 components representing 94.1%of the total amount‚ and eugenol was the major component in the essential oils of C. tamala leaves. In the antioxidant activity‚ anti-oxidant potentials of Cinnamomum oil and oleoresins for mustard oil have been evaluated by different methods such as peroxide‚ p-anisidine‚ thiobarbituric

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

What distinguishes the atoms of one element form the atoms of another? Elements are different because they contain different numbers of protons. 27. How do the isotopes of a given element differ from one another? Isotopes of an element

the inner mitochondrial membrane leaky to H+. Explain how this could cause weight loss. In chemiosmosis‚ NADH are passed along the electron transport chain‚ with energy used to pump protons across the inner mitochondrial membrane. As the protons are transferred across‚ a proton gradient is created. These protons can come back across the membrane with the help of the enzyme ATP synthase‚ thereby producing energy (ATP). If the membrane becomes leaky because of DNP‚ hydrogen ions would not be routed
