ANALYSIS OF ASPIRIN: SPECTROPHOTOMETRY The purpose of this experiment is to evaluate the percent aspirin on a commercial aspirin tablet using an instrumental method‚ spectrophotometry. In a spectrophotometer‚ light from a strong lamp passes through a monochromator‚ which breaks the light into its component colors using a grating‚ then uses mirrors and slits to direct a light beam of the desired wavelength through the sample compartment‚ where you place a tube (cuvette) of solution. A detector

Diola; ladyjewellyndiola@yahoo.com Abstract Synthesis of 3‚4-dihydro-3-(p-methylphenyl)-1‚2-(2h)-benzoxazine involves the nucleophillic addition of the 1 °amine group upon the carbonyly group of the salicylaldehyde‚ the reduction of imine to amine and the addition of paraformaldehyde to proceed ring closure. The experiment prepared the product through Mannich reaction‚ a multicomponent condensation synthesis between ketone‚ aldehydes‚ enols and amines. Biosynthesis of benzoaxazines

Introduction Organic synthesis is the process where a desired organic compound is constructed or prepared from commercially available materials. The objective of organic synthesis is to design the simplest synthetic routes to a molecule. Aspirin‚ also known as acetylsalicylic acid is as salicylate drug often used as analgesic

The crude product (aspirin) was purified in the last lab‚ using recrystallization‚ in which we dissolved the crude product with hot ethanol. We then added 25 mL of water until the product reformed (the solution became cloudy white) and redissolved the solid with hot ethanol. The solution was allowed to cool for a week‚ and crystals of purified solid were formed. In order to analyze this purified product‚ we determined the melting point by placing a small sample of the aspirin in a capillary tube

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We
