What is the molecular formula of aspirin?
C₉H₈O₄
Aspirin/Formula
Is aspirin made from crude oil?
While early aspirin-like medicines were made from natural sources like willow bark, modern aspirin is completely chemically synthesized. Aspirin simply contains a chemical that just so happens to be a natural part of crude oil and gasoline (it’s also formed by volcanoes and forest fires).
What is the correct structural formula for aspirin?
Aspirin Chemical Formula
| Chemical Formula of Aspirin (Acetylsalicylic acid) | C9H8O4 |
|---|---|
| Extended Molecular Formula of Aspirin | CH3COOC6H4COOH |
How do you make aspirin in a lab?
To prepare aspirin, salicylic acid is reacted with an excess of acetic anhydride. A small amount of a strong acid is used as a catalyst which speeds up the reaction. In this experiment, phosphoric acid will be used as the catalyst. The excess acetic acid will be quenched with the addition of water.
How is aspirin oil made?
In fact, the starting material for the chemical synthesis of aspirin is benzene, derived from petroleum. This is then converted to phenol which in turn is converted to salicylic acid which is then converted to acetylsalicylic acid or ASA, which we know as aspirin.
What is the synthetic material of aspirin?
salicylic acid
Yet, while aspirin has been one of the most popular pharmaceutical agents of the past one hundred years, it is actually a synthetic derivative of the natural substance salicylic acid—the associated healing properties of which have been known for millennia.
How do you calculate the theoretical yield of aspirin?
question 1
- Moles of Salicylic Acid = Moles of Aspirin —> 2 moles of Salicylic Acid makes 2 moles of Asprin.
- Molar Mass of Aspirin = 180.16 g.
- Theoretical yield of Aspirin (g) = (2 moles)(molar mass of aspirin) = 2.000(180.16) = 360.3 grams.
How do you make aspirin?
How do you calculate aspirin yield?
Using the theoretical and actual you can calculate percent yield.
- Actual Yield of Aspirin in lab after filtered/dried (mock value) = 370 g.
- Mass of Theoretical Yield of Aspirin (mock value) = 360.3 g.
- Percent Yield = (Actual ÷ Theoretical) x 100 = (370 ÷ 360.3) x 100 = 103 %
How do you make aspirin a level chemistry?
SYNTHESIS OF ASPIRIN (acetylsalicylic acid)
- Place 2.0 g (0.015 mole) of salicylic acid in a 125-mL Erlenmeyer flask.
- Add 5 mL (0.05 mole) of acetic anhydride, followed by 5 drops of conc.
- Heat the flask gently on the steam bath for at least 10 minutes.
- Allow the flask to cool to room temperature.
How do you make aspirin tablets?
Method of Preparationof Aspirin tablet: An enough granulating agent (water) was added slowly to prepare wet mass. Granules were prepared by sieving method using a20# sieve. Further, granules were dried at 35-45ºC for six hours. The dried granules were stored in desiccators until compression of tablets.
Where does the oil in aspirin come from?
But the “oil” in aspirin isn’t like that. It’s not even oil at all. Aspirin simply contains a chemical that just so happens to be a natural part of crude oil and gasoline (it’s also formed by volcanoes and forest fires).
Which is the correct chemical formula for aspirin?
Aspirin is a medicine that is used worldwide as an anti-inflammatory or antipyretic agent. The chemical formula for the compound is C9H8O4 and its molecular weight is 180.159 g mol-1.
What is the chemical formula for crude oil?
Crude oil is basically a combination of various hydrocarbon molecules, which comprise of hydrogen, H and carbon, C atoms. Among the types of hydrocarbons present in crude oil, alkanes are predominant. Examples of such alkanes are ethane (C 2 H 6 ), butane (C 4 H 10) and propane (C 3 H 8 ).
How is the synthesis of aspirin a esterification reaction?
The synthesis of aspirin is classified as an esterification reaction. Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid’s hydroxyl group into an ester group (R-OH → R-OCOCH3).
