must be discovered. Panacetin tablets are known to contain aspirin‚ acetaminophen‚ and sucrose; therefore‚ the tablets tested‚ containing aspirin and sucrose‚ are thought to contain an unknown of something similar to that of acetaminophen such as acetanilide or phenacetin. Another problem trying to be sought out in the experiments is whether or not the composition of Panacetin as stated on the label is accurate. The experiment involved the separation of the unknown from the Panacetin by first isolating

molecular formula would be C8H11N with a HDI of 4. Looking at the IR spectroscopy‚ there is a sharp peak at around 3000 cm-1‚ which indicates C-H bonds. At around 1600 cm-1‚ we see a peak which tells us there are C=C that might corresponds to an aromatic benzene ring‚ which I proved using the NMR. The Nitrogen is also present on the IR spectroscopy leaving its mark with a peak at around 3200 – 3500 cm-1. Lastly‚ I finalized my structure using the NMR spectroscopy. With the information I have collected

Organic Chemistry Laboratory ABSTRACT In this experiment‚ acetanilide was used as the pure organic compound. Acetylation of aniline and acetic anhydride yields the crude product or crude acetanilide. The crude acetanilide was purified by dissolving it in hot water and then the solution was cooled slowly by placing in an ice bath. The yielded crystals were pure acetanilide since molecules of other compounds present in the crude acetanilide were excluded from the growing crystal lattice. Lattice is

Scent-Infused Textiles consumer acceptance of fragrance-embedded textiles. Consumer willingness of finished products. The Sensory Perception Technologies (SPT) allows textile producers to weave particles of moisturisers‚ deodorants‚ fragrances and even anti-tobacco agents into fabrics. "Early trials have proved SPT a success with many global clothing companies interested‚" ICI‚ whose fragrances unit Quest developed the technology. ICI said the technology allows fabric makers to incorporate tiny

How It Is Synthesized Methamphetamine was first synthesized from ephedrine in Japan in 1893 by chemist Nagai Nagayoshi. In 1919‚ crystallized methamphetamine was synthesized by Akira Ogata via reduction of ephedrine using red phosphorus and iodine. Synthesis is relatively simple‚ but entails risk with flammable and corrosive chemicals‚ particularly the solvents used in extraction and purification; therefore‚ illicit production is often discovered by fires and explosions caused by the improper
