PREPARATION OF ASPIRIN USING TECHNIQUE AND TESTING METHOD
INTODUCTION
In this unit, we will be using techniques and testing methods to
prepare and test for aspirin. It is also called acetylsalicylic. The
aim of this unit is to accurately prepare, test the purity and
describe using methods of how aspirin (the organic solid) is made
in the industry. The organic solid (aspirin) is a medicine used to
bring down fever, inflammation and reduced pain. It is normally
used as normal painkillers such as toothaches, headaches and to
cure common cold symptoms.
After the preparation of the organic solid we will test the purity and
compare it to laboratory and industrial process of their preparation of
aspirin. To prepare the organic solid (aspirin), we use salicylic acid
(acetylation with acetic anhydride).
To prepare and test the purity, we are going to have a two
parts experiments.
Apparatus for part one of the experiment we are going to
need,
10cm3 measuring cylinder
Sulfuric acid (concentrated)
Spatula
Deionized or distilled water
Thermometer
250 cm3 beaker
Filter paper
Filtration apparatus to reduce pressure
