This is why my total mass recovered is only 2. Aspirin Separation Transfer to funnel and extract by using two, 25ml portions of aqueous 1M Sodium Hydroxide. The percent recovery of acetaminophen of the overall reaction was not required.

Thus, the melting point of the pure acetaminophen would be expected to be higher than that of the crude acetaminophen. We tried to reduce the temperature, but it was already too hot and the air condenser burst off and broke.

Separating the Components of Panacetin

Acetylsalicylic acid, also known as aspirin, is one of the most widely used medications to reduce fever and is also used as a pain killer. The intensity of this was enough to impart color to the crude acetaminophen.

During the unknown separation, the aspirator evaporated the the solvent. An ice bath was used to encourage crystal growth. Heating was employed so that salicylic acid would melt and react with acetic anhydride.

To determine if the label reads correctly, we need to find all of our percent recoveries. When placed in water, the citric acid and sodium hydrogencarbonate in the tablet react to produce bubbles of carbon dioxide.

Work in a well-ventilated area or fume cupboard Wear eye protection safety glasses or goggles. The theoretical melting point of acetaminophen is Phenacetin and Acetinilide being broken down into salts helps us express that, Panacetin and dichloromethane should dissolve the aspirin and our unknown substance, but leave our sucrose behind that can be extracted by filtration.

Treatment is aimed at removing the paracetamol from the body and replenishing glutathione. Everything looked to be dissolved, however my percent recovery proves to me that I was very close, just not close enough to get a within the desired sucrose range. The flask is secured to prevent tipping.

The calculations for percent yield was shown in Table 6. This, dissolves the aspirin and the unknown components, leaving us a powdery looking substance called sucrose, that will need to be filtered.

We know that Panacetin is made up of sucrose, aspirin and some other unknown substance. If I had mixed the Panacetin a little more I would have probably made the range, instead of missing it by 1.

The percent yield was Other tests that were performed were summarized in Table 7. But by cooling the substance we were able to recover the dichlormethane and then re evaporate until I only saw the solid substance remain.acetaminophen from hot (boiling) water using a hot plate.

4. 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. 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!
