Ibuprofen is (2RS)-2-[4-(2-methylpropyl) phenyl] propanoic acid. It is white or almost white, crystalline powder or colourless crystals. It is practically insoluble in water, freely soluble in acetone, in methanol and in methylene chloride. Ibuprofen is used as analgesic and anti-inflammatory (British Pharmacopoeia 2009). • Emu oil, EMU SPIRIT, Middleborough Road, Box Hill South, Australia. According to the manufacturer, Spirit Oil of Emu contains…

The goal of this experiment was to use the technique of thin layer chromatography (TLC) to identify the active analgesic ingredient of Advil and monitor the transesterification of methyl salicylate from acetylsalicylic acid. The synthesized methyl salicylate was then purified using acid-base chemistry and analyzed using H NMR spectroscopy. Identification of a proper mobile phase to separate common analgesics used in over-the-counter pain relievers was essential in being able to determine the…

Experiment 5: Separating Ferrocene and Acetylferrocene by Adsorption Column Chromatography AIM The primary goal of this experiment is to separate ferrocene and acetylferrocene using adsorption column chromatography. Additionally, a dry pack method with a micro scale column will be implemented, and the percent recovery for each compound will be computed. TABLE OF PHYSICAL PROPERTIES AND HAZARDS WITH STRUCTURES Ferrocene: - Physical Property: Solid Molecular Weight: 186.04 g/mole Boiling…

(in ppm): δ = 3.02 (s, 2H), 3.75 (s, 4H), 7.04 (s, 4H). Williamson Ether Synthesis 4-methoxy-phenoxy benzyl ether In a 100-mL round bottom flask 1.179 g of 4-methoxyphenol (1.0 equiv.), 2.62 g of potassium carbonate (2.0 equiv.) and ¬¬9.51 mL of acetone [1M] were combined. 1.01 mL benzyl bromide (0.9 equiv.) was then carefully added to the reaction mixture. The reaction flask was then placed into a sand filled heating mantle and attached to a reflux apparatus. Whilst refluxing, the reaction…

that is consumed. Fermentation During the fermentation process, there are many substances that are created in alcoholic beverages. These substances are called congeners. They are what gives distilled alcohol its flavor and smell. Congeners have acetone, esters and acetaldehyde in them.…

of 0.2 LNMFO + 0.8 BFO with LNMFO as ferrimagnetic and BFO as ferroelectric phase were prepared by the standard solid state reaction method. To prepare BFO stoichiometric amounts of high purity Bi2O3, and Fe2O3 were weighed and mixed thoroughly in acetone media for 5–6 h. The mixed powder of BFO was calcined at 800 °C in a closed alumina crucible for 4 h and then pre-sintered at 850°C for 4 h. High purity Li2CO3, NiO, MnCO3 and Fe2O3 were mixed in stoichiometric amounts to prepare LNMFO by the…

accurately weighed and extracted with a solvent mixture containing 40 ml acetone and 60 ml hexane and 0.1g of magnesium carbonate by using a pestle and mortar. The residue was allowed to settle and decanted slowly in a separating funnel; it was then washed twice with 25 ml portion of acetone and 25 ml hexane and then repeatedly washed with water. The upper layer was transferred to a 100 ml volumetric flask containing 9 ml acetone and volume was made up with hexane. The total carotenoid was…

Methamphetamine- History and Global Policy Amphetamine drugs are the second mostly used drugs in the world (Gunter, 2007). Amphetamine was first made in Germany in 1887 and was initially used to treat asthma and colds. In 1919, a Japanese, Nagayoshi Nagai made Methamphetamine (Meth) from ephedrine. During the first world war, to keep pilots awake in Germany, USA, Japan and Britannia, they were given methamphetamine. In the 1950s, meth was largely abused by students, athletes, and drivers as an…

A novel solid-phase synthesis methodology of N-substituted-2-aminothiazolo[4,5-b]pyrazine derivatives was developed. The key step in this synthesis strategy is tandem reaction of isothiocyanate terminated resin 2 with o-halo-2-aminopyrazine, affording cyclized 2-aminothiazolo[4,5-b]pyrazine resin 4. To increase the diversity of our library, Suzuki coupling reaction was performed at the position C6. Further functionalization of 2-aminothiazolo[4,5-b]pyrazine core skeleton with various…

Compounds 221 A slightly modified method of Wang et al. (2013) was used for extraction of free and bound 222 phenolics. For free phenolic compounds, 1 ± 0.001 g of the roasted maize flour was weighed into a 223 glass vial, 15 mL of 60% chilled aqueous acetone added and sonicated for 10 min at 20°C in the…
