Tablets such as panadol usually contain mg of paracetamol acetaminophen. Procedure to determine the paracetamol acetaminophen content in commercially available tablets: Separation of paracetamol acetaminophen from commercially available tablets: Place 2 tablets in 20 mL of propanone acetone in a small conical flask suspended in a beaker of warm water.

When the tablets have broken up, filter the mixture to remove the undissolved material which will include the binding agents and fillers in the tablets.

Leave the filtrate overnight in a fume cupboard to evaporate off the propanone acetone. The remaining solid is impure paracetamol acetaminophen. Purification of the Paracetamol acetaminophen Step 1: Add 10 mL water to the impure paracetamol acetaminophen and heat gently to dissolve it.

Filter off any insoluble substances using a hot glass filter funnel using a cold funnel will cause the paracetamol to crystallize out in the funnel, reducing the yield Step 3: Cool the filtrate to crystallize the paracetamol acetaminophen.

Filter the mixture to separate the insoluble paracetamol acetaminophen from the filtrate solution. Dry the pure paracetamol acetaminophen in a warm oven. Weigh the dry pure paracetamol. Safety Concerns Propanone acetone is volatile and highly flammable. Keep away from flames.

Work in a well-ventilated area or fume cupboard Wear eye protection safety glasses or goggles. DO NOT taste the paracetamol! It is possible to buy fizzy paracetamol tablets.

Paracetamol - Wikipedia

In these tablets the paracetamol has been mixed with citric acid 2-hydroxypropane-1,2,3-tricarboxylic acid and sodium hydrogencarbonate sodium bicarbonate. When placed in water, the citric acid and sodium hydrogencarbonate in the tablet react to produce bubbles of carbon dioxide.

The bubbles of carbon dioxide gas help break the tablet up into smaller pieces that are easier to swallow.


Do you understand this?The acetaminophen sample should be labeled with your name, the mass of the acetaminophen, the percent yield, and its melting point. NOTE: Don't use your acetaminophen for a headache! Will Jeffries 11/12/11 Period Two Organic Chemistry Extraction and Evaporation.

Identify the product by its melting point and determine the yield (next week). -OH, NH HNC=O. Recrystallization of Solids. 1. Dissolve the solid in a minimum amount of hot solvent. 2. If necessary, filter the hot solution if everything doesn’t.

The synthesis of Acetaminophen is based on the amine group of p-aminophenol being acetylated by acetic anhydride to form an amide functional group. Acetaminophen is isolated as a crude solid which is then recrystallized to purify the product.
