Identification of Unknown Organic Compounds by Melting Point‚ Boiling Point‚ and Infrared Spectroscopy Methods and Background The goal of this laboratory experiment was to determine the structure and identity of an unknown solid and an unknown liquid by using elemental analysis‚ index of hydrogen deficiency‚ infrared spectroscopy‚ melting point (for solid)‚ and boiling point (for liquid). In this laboratory‚ we were given unknown solid “C” and unknown liquid “D”. The empirical formula

yield of the pyrrolidine enamine. This condition was leaded good yields (73.6%) without side reactions. Acylation gave an enol form (71.7%) and a keto form (28.3%) of 2-acetylcyclohexanone mixture‚ the composition of which was determined by 1H-NMR spectroscopy. Key words : pyrrolidine‚ enamine‚ mild condition‚ NMR 1. Introduction The formation reactions of carbon-carbon bonds are important in organic synthesis [1-5]. In general‚ acylation reaction is one of the important carbon-carbon forming reactions

As for second method‚ we are using the Spartan modeling software‚ where we are able to draw out each of the functional group and have the software calculate the theoretical bond strength for us. And lastly‚ the IR spectroscopy are used is this experiment to measure the bond strength of each compound‚ and all the significant data are being collected in our lab notebook in order to further compare with theoretical bond strength. IR spectrophotometer reads off the amount

The goal of the experiment was to use UV/VIS spectroscopy to collect data to quantify acetaminophen‚ aspirin‚ and caffeine from a migraine tablet where there is heavy spectral interference using Target Factor Analysis1. The migraine tablet has other ingredients in it like FD&C blue #1‚ stearic acid‚ and saccharin. Saccharin is the ingredient thought to have the biggest interference and was used as the experimental basis2. Instruments: UV/VIS spectroscopy was used to analyze the absorption spectra

its conduction has never been reported. In this communication‚ we report a novel and facile method to hydrogenate graphene by using bulk amounts of catalyst placed upstream of the graphene flake films in the hydrogen flow as depicted in Scheme 1. Raman scattering and FTIR investigation are presented to study the hydrogenated graphene. Additionally‚ we looked into the wettability of the hydrogenated graphene surface because the C-H groups could dramatically decrease the surface energy5 and hence considerably
