Student number: 658184 Due Date: 19th Sept 2012 Paracetamol: Preparation‚ Purification and Analysis 1.1 Introduction Paracetamol (N- (4- hydroxyphenyl) ethanamide) or acetaminophen is a widely used analgesic (pain reliever) and antipyretic (fever reducer). It is a relatively safe drug though toxicity has been observed with very high doses.1 according to the British Pharmacopeia (BP) 111 paracetamol should contain between 95.0%- 105.0% of the stated product.2 It can be synthesised by reacting 4-aminophenol

Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

Introduction Paracetamol is a medication used to relieve fever‚ its chemical name is acetaminophen. Its molecular formula is CH3CONHC6H4OH and its molecular weight is 151.2 g/mol. The melting point of pure compound is in the range of 169-172 ℃. During lab Paracetamol medication was dissolved in water‚ purified and recrystallized again. The purpose of the experiment was to learn basic recrystallization techniques that include hot and cold filtration. During experimental procedure sample was purified

2.3 Determine the Value of Your PMO Value‚ like beauty‚ is in the eye of the beholder. Nevertheless‚ value can be determined by what one does‚ how well one does it‚ and often by how much it costs. Typically‚ organisations use business cases to prioritise limited resources for those elements or opportunities that provide the greatest ROI. Some of the challenges that put your PMO at risk of being under-valued include: Lack of a current‚ published operational plan Limited‚ or no‚ user involvement

Task 2 The extraction and purification of paracetamol from tablets In this experiment‚ I am trying to achieve an extraction of paracetamol from a commercial branded product. To test the purity I will find the melting point of the paracetamol. I will also be comparing my yield of paracetamol to the commercial tablets content of paracetamol as said on the packaging.
