Preparation of recrystallization
First the ibuprofen capsule was
weighed. After weighing it was
crushed with the help of a
mortar, once crushed it was
added to an Erlenmeyer and 15
ml of ethyl acetate were added
keeping in constant agitation
until it dissolved most of the
substance, in addition it required
a little heating to accelerate the
dissolution.
After it was heated, the solution
was taken to a gravity filtering
process using a funnel and the
previously weighed filter paper
to separate the insoluble solids.
After filtration the obtained
ethanolic acetate solution was
placed in a precipitated beaker
and transferred to a separatory
funnel or funnel. Next, 10 ml of a
previously prepared 1M NaOH
solution was added, the funnel
