Organic chemistry synthesis of aspirin and explain mechanism of reaction

Translated by GoogleSee original

From 43 C$ /h

We will prepare a chemical compound, aspirin, from its primitive compounds. We will also discuss its importance and the importance of preparing aspirin. This is a fascinating chemistry experiment because it combines organic chemistry with medical applications. Aspirin (acetylsalicylic acid) is manufactured from salicylic acid and acetic acid (or acetic anhydride) in the presence of sulfuric acid or phosphoric acid as a catalyst.

Aspirin preparation (acetylsalicylic acid)

Raw materials:

Salicylic acid

Acetic anhydride

Sulfuric acid (catalyst)

distilled water

Reaction mechanism:

The reaction is esterification of the hydroxyl group of salicylic acid by acetic anhydride, resulting in the formation of an acetyl ester and the release of acetic acid as a byproduct.

1. Salicylic acid reacts with acetic anhydride.

2. Sulfuric acid breaks the bond in acetic anhydride, which helps the hydroxyl group in salicylic acid react with the acetic group.

3. Acetylsalicylic acid (aspirin) is formed with the release of acetic acid.

The importance of aspirin:

As a pain reliever and antipyretic

anti-inflammatory

It is used to prevent blood clots and heart disease.

► Online Mathematics, Physics & Chemistry Tutor from Switzerland
► GCSE, IGCSE, A-Level, IB & International School Support
I completed my Master’s degree in Business Information Systems at a Swiss University of Applied Sciences, where my main academic focus was strongly connected to Mathematics, Physics, analytical thinking and problem-solving. This technical background shaped the way I teach today: clearly, logically and with a strong focus on real understanding.
► EXTENSIVE EXPERIENCE WITH GCSE, IGCSE, A-LEVEL, IB & INTERNATIONAL SCHOOL STUDENTS
With many years of teaching experience, I have successfully supported students from prestigious schools and highly demanding academic programmes, helping them strengthen their understanding, master exam techniques and achieve excellent progress in Mathematics, Physics and Chemistry.

► Exam Preparation & Academic Support

► GCSE & IGCSE Mathematics, Physics and Chemistry
I help students build a strong foundation through clear explanations, topic-by-topic revision and carefully selected exam-style practice. My lessons focus on understanding the core ideas, improving calculation skills, avoiding common mistakes and preparing students confidently for their final exams.

► A-Level Mathematics, Further Mathematics, Physics and Chemistry
A-Level subjects require deeper thinking, strong problem-solving ability and excellent exam technique.

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.
