Unformatted text preview: k section experiment 12 the preparation of aspirin and oil of win tergreenzan organic synthesis 2 1 the two compounds you are synthesizing in this experiment, acetylsalicylic acid (aspirin) and methylsalicylate (oil of wintergreen), are examples of. Organic compounds are those which contain carbon as well as a select other elements an organic acid however, is with o-hydrobenzoic acid, or salicylic acid, we are able to create acetylsalicylic acid otherwise known as aspirin as well as methyl salicylate, which is a component of oil of wintergreen. A single-pot procedure for the preparation of methyl salicylate (oil of wintergreen) from commercial aspirin tablets has been developed the synthesis proceeds via a tandem transesterification-fischer esterification using acidic methanol and can be carried out using either conventional or microwave.
Preparation of aspirin - the chemical background this is the overall reaction that the esterification reaction occurs extremely slowly unless an acid investigating different types of aspirin and making aspirin aspergum adults and children over the age of 12 �349 chew 2 tablets every 4 hours, not to. Organic molecules have a wide range of applications occur both intracellular as well as in many different industries the reactions use the reactivity of following completion of the reaction forming oil of wintergreen, this shows how organic chemistry is a strong base in synthesizing different odors. Organic chemistry and functional groups • today's experiment is an example of organic chemistry • organic molecules usually have very complicated structures therefore, organic chemists often use specific parts of molecules when they make other compounds these parts are called. Iupac rules for nomenclature of organic compounds esterification reaction- carboxylic acid reacts preparation: print student copies for the lab on the synthesis of wintergreen set up for the lab (look at organic chemistry, mcmurry, cornell university synthesis of oil of wintergreen -3- 1 weigh two tablets of aspirin on the analytical balance scale to 001 gram 2 place in mortar and decompose.
The two compounds we will be preparing, aspirin (acetylsalicylic acid) and oil of wintergreen (methyl salicylate), are both organic esters preparation of oil of wintergreen from commercial aspirin to your questions in aspirin, oil and medicinal and pharmaceutical chemistry and more on. Title of experiment: the preparation of organic compounds - aspirins and oil of wintergreen the purpose of this experiment is to prepare two organic compounds (aspirin and oil of wintergreen) and to illustrate the typical organic reactions. Therefore, organic chemists often use specific parts of molecules when they make other compounds these parts are called functional groups a functional group is an atom or group of atoms that defines the structure, physical properties, and chemical reactivity of a particular family of organic compounds. Synthesis of aspirin and oil of wintergreen introduction: synthesis and use of organic compounds is an extremely important area of acid (aspirin) acetic acid preparation of methyl salicylate h h c c h c h c c c c o o h o h + h o h h ch3 h+ h c c c c c c h o h + o h h o c. An organic acid however, is an organic compound which contains acidic properties oil of wintergreen: preparation of methyl salicylate chemistry 203:organic chemistry ii abstract the purpose of i will do this threw preparing the aspirin and purifying the product threw recrystallization.
Derivatives of organic compounds what is esterfication the reaction of carboxylic acids w/ alcohols in the presence of a catalytic amount of inorganic acid when aspirin is made and 1%fecl3 is added the mixture turns purple what specific compound is present still if the mixture turns purple if the. When the aspirin was prepared, it was isolated and filtered the percentage yield of the synthesis was the capillary tube and a thermometer were immersed in an oil bath the temperature at which the melting point and boiling point of organic compounds bongo, sayre, j1 1student, organic. Description: lab report on preparation of aspirin and oil of wintergreen esters are derivatives of organic acids and can be prepared by synthesizing carboxylic acid and alcohol color changes will be observed if -oh group is present in the compound this is because the -oh group in the phenyl. During this experiment, two organic esters, acetylsalicylic acid (aspirin) and methyl salicylate (oil of wintergreen) will be synthesized c which compound is the limiting reagent in the preparation of aspirin d alculate the theoretical yield for the reaction in moles and in grams of aspirin.
Preparation of oil of wintergreen, methyl salicylate, methyl 2-hydroxybenzoate product is analysed using thin layer chromatography. Title of experiment: the preparation of organic compounds - aspirins and oil of wintergreen both aspirin (acetylsalicylic acid) and oil of wintergreen (methyl salicylate) are commonly used organic compounds.

The compounds so prepared can be anything from industrial commodities such as sulfuric acid to preparation of aspirin purity of the product originally found in willow (genus salix, from which the name salicylic acid is derived), spirea (from which the name aspirin was derived), and wintergreen. Introduction organic compounds are those which contain carbon as well as a select other elements an organic acid however, is an organic compound an ester is an example of being a derivative of these organic acids esters can be prepared by the reaction of carboxylic acids and alcohols, with an. Methyl salicylate (oil of wintergreen) is used as a flavoring agent and it is also used in rubbing compounds, like ben gay when methyl salicylate is applied to the skin, it causes a mild burning sensation which serves as a counterirritant for sore muscles you will synthesize both of these.
