SYNTHESIS OF ASPIRIN EQUATION

In this experiment you will synthesize aspirin (acetylsalicylic acid, C9H8O4), purify it, and determine the percent yield. The purity of the product will be confirmed. The synthesis reaction of aspirin is shown below: Since acetic acid is very soluble in . Now set the y-intercept to 0 and check the display equation box. To add.

SYNTHESIS OF ASPIRIN MECHANISM

periment was to synthesize aspirin by reacting salicylic acid The actual yield of aspirin synthesized was .. Figure 2: Synthesis of Aspirin Mechanism. Synthesis of aspirin from salicylic acid occurs by acetylation process in acidic Mechanism: Molecular weight of acetyl salicylic acid (aspirin) = g/mole.

RECRYSTALLIZATION OF ASPIRIN PDF

Aspirin. A curriculum resource for post chemistry and science courses .. On the next page is a list of the stages in recrystallisation, but not necessarily in the. Acetylsalicylic acid was recrystallized from ethanol in a crystallizer which recrystallization techniques and solvents were used to produce acetyl- salicylic acid.

RECRYSTALLIZATION OF ASPIRIN

In this experiment you will prepare and purify aspirin and test the product. To purify by recrystallization, place your crude aspirin in a 50 mL Erlenmeyer flask. Trace amounts of salicylic remaining are removed by recrystallization from an If your aspirin tests positive for salicylic acid, recrystallize the impure aspirin.
