I find that aspirin is best for my arthritic hip beause it seems to have a lubricating effect on the joint. Industrial production of Aspirin is dependent on the company producing the drug; however the general method of production is known as slugging or dry-granulation. Obtain approximately 2 g of salicylic acid and de-termine its mass accurately; record the ex act value in your data table. The first of these that is used is the procedure of weighing by difference. The drug is also beneficial in helping to ward off Let say you are working in a lab to perform the synthesis of a molecule. Do this step in the hood. hardness in a machine such as the Schleuniger (or Heberlein) Tablet inflammation. In the industrial synthesis of aspirin, 200 kg of salicylic acid, C7H6O3, and 150 kg of acetic anhydride, (CH3CO)2O, form acetylsalicylic acid, C9H8O4, (aspirin) and acetic acid, C2H4O2. effective pain reliever that did not have the side effects of salicylic "Aspirin," ; Heat the flask gently on the steam bath for at least 10 minutes.

In the basics we will assume you will need a reactor (round-bottom flask), and a distillation column to separate your compound from the others (solvent, remaining reactants, possible side products). A balanced equation for the synthesis of Aspirin from Salicylic Acid and Acetic Anhydride is the following: Salicylic acid + acetic anhydride –> Acetylsalicylic acid + Acetic acid (C7H6O3) + (C4H6O3) –> (C9H8O4) + (C2H4O2) 0.
