Synthèse de la 1-Phényl-2-propanone (P2P) à partir du malonate de diéthyle (phénylacétyl)

[G.Patton]

Avez-vous compris votre question ? Voulez-vous parler de distillation simple plutôt que de distillation sous vide ? Vous pouvez, 216 degrés C est le point d'ébullition dans des conditions normales.

Can this synthesis be up scaled please

 

[G.Patton]

Hello, yes, sure

 

[Pinkbay]

Is there any other way to isolate the phenylacetic acid besides putting it in the refrigerator? Will not separating affect my future work?

 

[William D.]

You can crystallize this in a cool place and filter after. In another case, you can distill the fractions. For the following steps, you cannot leave PPA.

 

[Pinkbay]

Sir, how long does the PAA crystallization process take?

 

[greatwhiteshark]

I would like to know if this synthesis is also working with phosphoric acid ( h3pO4) I appreciate your work and time

 

[greatwhiteshark]

And what would be the amount ( phosphoric acid 85%)
