Synthesising and testing the purity of acetylsalicylic acid biology essay

Organic synthesis aspirin aim biology essay to synthesise acetylsalicylic acid, to find the pureness of acetylsalicylic acid utilizing chemical trial, and to find the per centum of output acetylsalicylic acid. • materials and methods: this experiment called for the synthesis of acetylsalicylic acid, or aspirin, by using salicylic acid, acetic anhydride, sulfuric acid, and vacuum filtration the salicylic acid and the acetic anhydride were mixed in a flask. An acid which has a higher concentration of h+ ions in solution is a stronger acid, and an acid that has a lower concentration of h+ ions in solution is a weaker acid stronger acids are typically used in desiccation and condensation reactions, as they are able to protonate other compounds.

synthesising and testing the purity of acetylsalicylic acid biology essay The common chemical name isa acetylsalicylic acid salicylic acid was identified and isolated from the bark of a willow tree but it could non be synthesised in research lab in 1893, felix hoffman jr , a chemist found out a practical manner for synthesising an ester derived function of salicylic acid, acetylsalicylic acid.

Iron (iii) chloride test: this test is used to detect the presence of salicylic acid, and therefore indicate an impure sample reaction with sodium bicarbonate: aspirin will dissolve in sodium bicarbonate solution to produce carbon dioxide and sodium acetylsalicylate salt.

Exercise 11 synthesis of aspirin (acetylsalicylic acid from salicylic acid) sharmaine s bungabong group 2 5l i introduction organic synthesis is an important aspect in the industry of organic chemistry this aspect of organic chemistry has contributed much to the knowledge there is regarding the. Aspirin (2-ethanoyloxybenzenecarboxylic acid) he called the new medicine aspirin (‘a’ for acetyl – the systematic name for the compound at the time was acetylsalicylic acid, ‘spir’ for spirea, the meadowsweet plant) nowadays chemists use the systematic name, ethanoyl, instead of acetyl.

1 label three test tubes place a few crystals of salicylic acid into test tube #1, a small sample of your aspirin into test tube #2, and a small sample of crushed commercial aspirin into #3 add 5 ml of deionized water to each test tube and swirl to dissolve the crystals 2 add 10 drops of 1% ferric chloride to each test tube 3. The purity of the product as a pharmaceutical is crucial, and synthesis of aspirin from salicylic acid salicylic acid acetic anhydride sodium acetate acetylsalicylic acid acetic acid molecular mass 13812 g mol-1 10209 g mol-1 8203 g mol-1 18016 g mol-1 6005 g mol-1.
