Salicylic acid is naturally found in the bark of willow trees, as well as in certain fruits like strawberries and raspberries. It can also be synthesized from plant-based compounds like methyl salicylate, found in wintergreen oil.
Wintergreen oil is a pale yellow or pinkish fluid liquid that is strongly aromatic with a sweet woody odor (components: methyl salicylate (approx. 98%), a-pinene, myrcene, delta-3-carene, limonene, 3,7-guaiadiene, delta-cadinene)Main component is nothing else than the main component in aspirin, 1 mL wintergreen oil is equivalent to six adult aspirin pills, so it is rather toxic.The formula of methyl salicylate (other names: methyl 2-hydroxybenzoate, salicylic acid methyl ester) is found by linking to 'Related links' below this answering page.
The methyl group is -CH3.
The molecular formula for methyl butyrate, also known as methyl butanoate, is C5H10O2.
The "methyl" and "methylene" come from their chemical structures. Something that has "methyl" in its name contains a methyl group - CH3. A common chemical like this is methyl alcohol - CH3OH. The methylene group is CH2. The blue and violet? That's what color they are.
salicylic acid (an acid) is more polar than methyl salicylate (an ester)
When salicylic acid reacts with methanol , Methyl salicylate (commonly known as Oil of Wintergreen) is formed. The chemical formula of Methyl salicylate is C6H4(OH)COOCH3 , It can also be written as C8H8O3
Methyl salicylate is produced from the reaction of salicylic acid and methyl alcohol. It is commonly known as oil of wintergreen and is often used as a flavoring agent or in topical creams for its characteristic wintergreen aroma.
why hydrogen of COOH group is removed in the preparation of methyl salicylate from salicylic acid in the presence of sulphuric acid
The products of the acid hydrolysis of methyl salicylate are salicylic acid and methanol. Acids catalyze the cleavage of the ester bond between the methyl group and the salicylate group, resulting in the formation of these two compounds. The reaction requires heat and produces acidic conditions to facilitate the hydrolysis process.
Bismuth salicylate C7H5BiO4 Ignoring inactive ingredients, the salicylate salt of bismuth is the active ingredient and also lends the wintergreenish flavor as Methyl salicylate is the main component of wintergreen and is a salt or ester of salicylic acid. The methyl ester is the chief component of oil of wintergreen. Salicylic acid is also the main component of aspirin, chemically known as acetylsalicylic acid, commonly abbreviated as ASA in drug preparations.
Salicylic acid is naturally found in the bark of willow trees, as well as in certain fruits like strawberries and raspberries. It can also be synthesized from plant-based compounds like methyl salicylate, found in wintergreen oil.
The active ingredient in aspirin is acetyl salicylic acid. It was first discovered in willow bark by an Oxford scientist in 1763.
Sulfuric acid is used in the preparation of methyl salicylate as a catalyst to promote the esterification reaction between salicylic acid and methanol. It helps to increase the reaction rate and yield of the desired product. Additionally, sulfuric acid aids in the removal of water formed during the reaction to shift the equilibrium towards the formation of methyl salicylate.
Intermolecular forces, specifically hydrogen bonding between methyl alcohol molecules, must be overcome for methyl alcohol to evaporate. The hydrogen bonds between molecules need to be disrupted in order for the liquid to transition into a gas during evaporation.
Bluestar ointment contains ingredients such as camphor, menthol, eucalyptus oil, and salicylic acid. These ingredients work together to provide relief for various skin conditions such as itching, inflammation, and fungal infections.
Methyl stearate is a saturated fatty acid methyl ester, while methyl oleate is an unsaturated fatty acid methyl ester. Methyl oleate has a higher degree of unsaturation due to a double bond in its carbon chain, making it more flexible and less rigid than methyl stearate. Additionally, methyl oleate may have different physical properties, such as a lower melting point, compared to methyl stearate.
