A synthetic pathway for the stated reaction, showing all the
curly arrows from beginning to end
(Mechanism)
In detail, 6.0 g ß-CD, beta-Cyclodextrin (previously dried at
100.0°C for 12 h) was dissolved in a mixture of 40.0 mL of dried
N,N-dimethylformamide (DMF) and 14.0 mL of dried triethylamine
(TEA) while magnetically stirred for more than 20 min. Then, 5.0 mL
of acryloyl chloride was slowly dropped into the mixture at 0°C
while in an atmosphere of nitrogen. The resulting mixture was
stirred for another 30 min at room temperature and then
vacuum-filtrated. Then, acetone was added to the filtrate drop by
drop to obtain a precipitation product. The solvent was removed,
and the precipitate was washed with acetone at least three times to
further purify the product. Finally, the precipitate was collected
and dried at room temperature under a vacuum.
Thank you
beta CD means; beta-Cyclodextrin

Step 1. Preparation and Recrystallization of a Diastereomeric Salt - Synthesis of (R,R)-1,2-Diammoniumcyclohexane mono-(+)-tartrate: In a 150 ml beaker, L-(+)-Tartaric acid (7.5 g, 0.05 mol) is dissolved in 25 mL of distilled water. The solution is stirred as 11.4 g (12.2 mL, 0.10 mol) of 1,2-diaminocyclohexane is added carefully in one portion. (The addition of the diamine is exothermic.) A slurry is formed initially but complete dissolution is observed once addition...

Room temperature method using phenolphthalein Dissolve phenolphthalein (0.005 mole, 1.59 g), solid sodium hydroxide (0.4 g) and tetraethylammonium chloride (TEA) (0.5 g) in 50 mL of deionised water in a 200 ml beaker, then add a magnetic stirrer bar. Add 35mL of dichloromethane to the beaker. Cover the top of the beaker with aluminium foil. Set up a magnetic stirrer to provide continuous stirring at an intermediate speed....
When setting up the reflux condenser, does it matter if the
water flows into the bottom or the top of the condenser? If so,
does it have to flow into the bottom or the top, and why? If not,
why does it not matter?

Extraction of solids: Experiment outlined below
Draw a “roadmap” of the experiment, containing chemical
structures and “layers” (organic and aqueous). This should contain
the individual reactions occurring in each step, and show which
layer the various components are present. Make sure you think about
whether the acetaminophen, caffeine and aspirin are neutral,
protonated or deprotonated.
