Synthesis of aspirin synthesis purification characterization aspirin: some background acetyl salicylic acid (aspirin) organic background alcohols titrate potentiometrically the acetylsalicylic acid with a strong base and find pka o oh ho o ooho o o o-na+ + naoh + h2o. The goal of this experiment was to synthesize aspirin in this experiment aspirin, also known as acetylsalicylic acid, was synthesized from salicylic acid and acetic anhydride in the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group this method of forming acetylsalicylic acid [. Computer 22 advanced chemistry with vernier 22 - 1 the synthesis and analysis of aspirin aspirin, the ubiquitous pain reliever, goes by the chemical name acetylsalicylic acid. Felix hoffmann, a german chemist, produced a stable signifier of acetylsalicylic acid, more normally known as acetylsalicylic acid in 1897 aspirin is a derivative of salicylic acid that is a mild, nonnarcotic analgetic useful in the alleviation of concern and musculus and joint achings. Synthesis of aspirin by: jon torre purpose: to determine which of four catalysts yields the fastest reaction rate in the acetylation of salicylic acid (1) to form acetylsalicylic acid (2) reactions: procedure and results: aspirin synthesis tap water was heated on a steam bath in a 250 ml beakerthe temperature of an alcohol thermometer was equilibrated in a beaker of room temperature tap water.
Organic synthesis of aspirin chemistry formal lab essay sample abstract the purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin), and to become familiar with the optimum conditions needed for successful yields. Synthesis product contains about 99 % of o-hydroxybenzoic acid calculated for dry substance during aspirin synthesis the quality of finite product is defined first of all by salicylic acid purity. Aspirin essays analgesics are compounds used to reduce pain, antipyretics are compounds used to reduce fever one popular drug that does both is aspirin salicylic acid is reacted with acetic anhydride with the use of heat and sulfuric acid, which acts as a catalyst, to produce acetylsalicylic acid.
Synthesis of acetylsalicylic acid (aspirin) anna shahrour partner jocelyn barraza ta yong wang section 05 introduction aspirin is the common name for the compound acetylsalicylic acid, widely used as a fever reducer and as a painkiller. Within this experiment, acetylsalicylic acid, better known as aspirin, is synthesized from the reaction of acetic anhydride, salicylic acid, and sulfuric acid (used a catalyst) the procedure of the experiment itself employs vacuum filtration and recrystallization as methods of obtaining and purifying the product. Purification is needed to eliminate any salicylic acid and acetic anhydride that did not react, as well as the acetic acid product and phosphoric acid in this part, purification is not yet complete (it was continued on the recrystallization part. In this experiment, the product that was synthesized was acetylsalicylic acid, also known as aspirin water is an excellent solvent for the recrystallisation of benzoic acid at 10â°c only 21 g of benzoic acid dissolves in 1 liter of water, while at 95 â°c the solubility is 68 g/l the aspirin was prepared through the synthesis of. The experimental procedure of a recrystallization lab report for acetylsalicylic acid solvent selection is as follows: 1) take four dry, clean 10-cm test tubes and label them with the numbers 14 using plastic weighing dishes, weigh carefully and put into each test tube 0,1 g of acetylsalicylic acid.
Preparation, purification and analysis of aspirin (acetylsalicylic acid) synthesis: we will prepare aspirin by reacting salicylic acid 1 with an excess of acetic anhydride 2 to produce aspirin 3 and acetic acid 4: o oh. The kolbe synthesis for the production of salicylic acid was created by the german chemist hermann kolbe in this process, sodium phenoxide is heated with carbon dioxide under pressure (100 atm) and the mixture is then acidified to yield salicylic acid. Esterification reaction: the synthesis and purification of 2-acetoxybenzoic acid and subsequent analysis of the pure product (acetylsalicylic acid ) via thin-layer chromatography. 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.
Aspirin is a trade name for acetylsalicylic acid, a common analgesic acetylsalicylic acid is an acetic acid ester derivative of salicylic acid the earliest known uses of the drug can be traced back to the greek physician hippocrates in the fifth century bc. Theoretically, the ratio of the number of moles of the acetylsalicylic acid and the salicylic acid is 1:1 according to the equation below therefore, the weight of aspirin produced should be 315g theoretical weight of aspirin = number of moles ´ the mol wt of aspirin. Synthesis of aspirin lab report 2989 words | 12 pages abstract: the goal of this experiment was to synthesize aspirin in this experiment aspirin, also known as acetylsalicylic acid, was synthesized from salicylic acid and acetic anhydride.
Acetylsalicylic acid is used as analgesic, antipyretic, anticoagulant and anti-rheumatic it is also used as an additive in food, animal feed, drug and cosmetic low doses of aspirin may be given immediately after a heart attack to reduce the risk of another heart attack or death of cardiac tissue. This paper explores and proposes a more efficient method for the synthesis of organic compounds using a technique of process intensification - condensing synthesis and purification into one step studies were conducted regarding the production of acetylsalicylic acid (more commonly known as aspirin) and a hypothetical installation was designed. Acetylsalicylic acid lab september 15, 2005 september 23, 2005 objectives the objective of this lab experiment is to prepare aspirin (acetylsalicylic acid) by reacting salicylic acid and acetic anhydride. Microscale synthesis of acetylsalicylic acid essay synthesis of aspirin ling tecson gamido, mitchiko mariel m mizukami abstract acetylsalicylic acid, or also known as aspirin is known to be a drug that relives people of pain and is commonly used even today.
