point range is less than five degrees apart‚ meaning there were not many impurities in the final product. The H’ NMR of the starting material‚ trans cinnamic acid‚ is almost the exact same as the he H’ NMR of the final product. The only difference was the extra signal around 5 ppm. The reason behind the extra signal is the addition of the Bromine to the trans-cinnamic acid. The H’ NMR matched my predictions almost exactly‚ meaning the product is what was suppose to be obtained. All of the signals

Infrared was recorded on a Perkin-Elmer 1650 FT-IR spectrophotometer‚ using a sample in KBr disks. 1H NMR and 13C NMR spectra were recorded on a Varian Gemini (300 MHZ)‚ using TMS as an internal standard and DMSO-d6 as solvent. Mass spectra were taken on Shimadzu GCMS QP-1000EX instrument by direct inlet technique‚ at beam energy 70 eV. The 3-acetylquinolinone

hindrance of its benzene rings being so close together. It causes the molecule to twist. E-Stilbene on the other hand does not have to twist due to hindrance and thus has full conjugation. The recrystallized E-Stilbene product is mostly pure as its NMR matches the literature value for E-Stilbene except for the small peak at 6.6 ppm due to a small amount of leftover Z-Stilbene2. This reaction could be improved by using Bromine instead of Iodine because Iodine is very slow and it is possible that more

Chem 51LC Experiment 6 Lab Report Aldol Reaction Purpose: The purpose of this experiment is to be able to conduct an aldol condensation reaction using an unknown aldehyde and an unknown ketone. H NMR is used to identify the unknown aldehyde and ketone. Melting point is used to identify the aldol condensation reaction. Theory: Condensation reaction is also known as a dehydration reaction. In the mechanism of condensation reaction‚ a bond is formed between two molecules and creates water as a

Structural Elucidation The synthesized compound was structurally characterized by IR‚ NMR and mass spectropho-tometer. An IR spectral study was done with Shimadzu Corporation‚ Japan. An NMR spec-tral study was done with Bruker Fourier- NMR spectrometer. Mass spectra of the samples were recorded on a Waters e 2695-Waters 3100 instruments with ESI-PMT arrangement as the mode of ionization and type of detector respectively

benzyltriethylammonium chloride has both hydrophilic and hydrophobic properties‚ it could cross the phase boundary and facilitated the transport of the hydroxide ion from the aqueous phase to the organic phase. Expected spectral changes in IR and 13C-NMR Procedure To begin‚ 0.324g of cyclohexene was mixed with 1 ml of 50% aqueous sodium hydroxide‚ 1ml of chloroform and 0.040g of the phase transfer catalyst benzyltriethylammonium chloride. The reaction was stirred and heated at 40 degrees Celsius

If we were able to vacuum filter our product more‚ the percent yield would be close to 100%. 1. Assign the peaks in your NMR spectrum of your salicylic acid. See NMR spectrum on back 2. Assign the peaks in the IR spectrum of your salicylic acid. The IR spectrum was not performed since we ran out of time due to the fire alarm. 3. What was the purpose of the hydrochloric acid?

Finally‚ hydrolysis of the ester then provides (S)-ibuprofen in a relatively high yield. all reaction were monitored by TLC at room temperature with appropriate solvent system which states in experiment section. IR‚ 1H-NMR‚ 13C-NMR‚ polarimetry and melting point range were used to define the product and its purity.
