Why is sulphuric acid used in preparation of aspirin? - Quora

This report will explain the chemical properties of Aspirin as well as what the uses are, the history of the chemical, and the discovery of the molecule.

Aug 31, 2008 · Why is sulfuric acid used in the synthesis of aspirin

, also known as acetylsalicylic acid (abbreviated ), is a salicylate drug, often used as an to relieve minor aches and pains, as an to reduce fever, and as an medication. Aspirin also has an effect by inhibiting the production of thromboxane, which under normal circumstances binds platelet molecules together to create a patch over damaged walls of blood vessels.
It is the salicylate ester of acetic acid; in fact, its synthesis is classified as an esterification reaction:


Why is sulphuric acid used in preparation of aspirin

I will give a brief description of what Aspirin is, chemically speaking and where aspirin originates from....

(II) Discussion Back titration rather than direct titration was used because there was no suitable indicator for acetylsalicyclic acid and sodium hydroxide solution.


Step 1 - Find molar mass of aspirin and salicylic acid From the ..

This page looks in detail at the mechanism for the formation of esters from carboxylic acids and alcohols in the presence of concentrated sulphuric acid acting as the catalyst. It uses the formation of ethyl ethanoate from ethanoic acid and ethanol as a typical example.

Answer to Acetylsalicylic acid, commonly called aspirin, ..

History Innovated by the fact that ancient people use willow bark to ease pain, aspirin was first obtained from willow bark by a German chemist called Felix Hoffmann, in 1897....

Synthesising And Testing The Purity Of Acetylsalicylic Acid ..

Aspirin belongs to rhe group of s, but differs from most other s in the mechanism of action.
Aspirin's ability to suppress the production of prostaglandins and thromboxanes is due to its irreversible inactivation of the cyclooxygenase (PTGS) enzyme required for prostaglandin and thromboxane synthesis. Aspirin acts as an acetylating agent where an acetyl group is covalently attached to a serine residue in the active site of the enzyme, preventing arachidonate binding. This makes aspirin different from other s (such as and ), which are reversible inhibitors.

When making Aspirin, I know that sulfuric acid is used …

An overview of their role in brain physiology and a discussion on the potential of using DHA signaling in the development of treatments in patients suffering from stroke have been released by ().

One neuroprotectin and several resolvins have been shown to be biosynthesized by isolated trout brain cells providing the first evidence for the conservation of these structures from fish to humans as chemical signals in diverse biological systems (.
