Preparation Of Acetomynophen

set of Acetaminophen Acetaminophen is used to relieve meek to go over pain from headaches, muscle aches, menstrual periods, arctics and irritating throats, toothaches, backaches, and reactions to vaccinations (s calefactives), and to reduce fever. Preparation of acetaminophen involves treating an amine (p-aminophenol, with an acid anhydride to descriptor acetaminophen (p-acetamidophenol), the amide. routine: Preparation of Acetaminophen [pic] Procedure: 1. response Mixture-1.5 g of p-aminophenol (MW=109.1) was placed in 50 ml Erlenmeyer flask. With a graduate cylinder I added 4.5 ml of water and 1.7 ml of acetic anhydride (MW=102.1, d=1.08g/ml) too I placed magnetized stir bar in the flask and than I disturb the diverseness. 2. Isolation of scratchy Acetaminophen- I removed the flask from the hot plate to cool to style temperature. aft(prenominal) crystallization has occurred, I cool the categorization in an fruitcake bath and h ave the crystals by vacuum filtration on a vitiated Buchner funnel. I allowed the crystals to dry and I encumbrance the crude product and heedful the melting point. Latter I calculate the percentage yield. 3. Decolarization of Crude Acetaminophen 2.0 g of atomic number 11 dithionite was squirm in 15 ml of water in a 50 ml Erlenmeyer flask.

The crude acetaminophen was added to the flask. The alloy was awake and some of the acetaminophen dissolved during the process. Then the mixture was cold in an ice bath for 10 min. The purified worldly was stack away by vacuum filtration on a small Buchner funnel. After the crystals were dry the purified acetaminophen was weight an! d I ascertained the color. 4. crystallisation of Acetaminophen-the purified acetaminophen was placed in a 50 ml Erlenmeyer flask. The material from a solvent mixture was compose of 50% water and 50% methanol by volume. The solubility of acetaminophen in this solvent was:1g/5ml. After the solid dissolved the mixture was cool to room temperature and the flask was placed in ice bath. The crystals...If you want to get a full essay, instal it on our website: BestEssayCheap.com
