Síntesis de 4'-metilpropiofenona a partir de tolueno mediante la reacción de Friedel-Crafts (escala 1kg+)

El Sr. Seguridad al rescate....

Sí, será mejor que te asegures de llevar todo el equipo de protección. Porque si sigues este consejo y utilizas acero inoxidable, vas a tener un desastre entre manos. El acero inoxidable es atacado rápidamente por ácidos orgánicos y cloruros. Así que una vez que se calienta esta mezcla es mejor estar preparado para ejecutar .... o simplemente seguir con el vidrio

Tomorrow I'm starting the big day synthesis with a small batch.
I wanted to start with a small batch for my first try.
1.08 mol 100 Gr 95.2 mL propionyl chloride
1.12 mol 150 Gr: AlCl₃
2.81 mol 300 ml 261 Gr Toluene
I can use 50 ml more toluene. 350 ml
Toluene of 99.5% purity was dried and then distilled under vacuum. We follow the advice of the masters

Do not forget to pour it into cold water. Not water into the reaction mixture. This is very important.

Can you replace propionyl chloride with propionic anhydride for reaction?

 

[The-Hive]

try it and let us no do it on a small scale then compare it to using propionyl chloride

 

[William D.]

Do you think this reagent is more easy to buy? And cheaper? I think this is not so, but if you have it, you can go with such a route but with correction.

I finally managed to make the synthesis, I can't thank @William D. enough for helping me every step of the way, I am very grateful
Now I just need to distill the dirty 4'-methylpropiophenone under vacuum
