@@vibzzlab It would be difficult to do in the lab in the manner that it is done industrially, which is to pass air and steam through molten benzoic acid (plus ~2% catalyst) at ~250C. Apparently steam is not absolutely necessary, just to pass air through the substance, but yield is much less. I presume it could be done by melting the acid in a flask (at greater heat than the 181°C boiling point of phenol) along with a small quantity of copper oxide catalyst and bubbling air through it, while simultaneously distilling off the phenol. A short-path distillation would likely be necessary to resist clogs. If you try it, you must promise you won't curse me as you labor to clean your glassware afterwards. ;-) patents.google.com/patent/US3308167A/en

Very nice :D
another suggestion for purification, dissolve PhCOOH in NaOH and filter if you don't have other impurities and add HCl onto that
Information Dene ke liye thanks 👍
The Na2CO3 is reacting with the KMnO4 forming the precipitate so the KMnO4 isn’t able to react with the aldehyde fully, try changing Na2CO3 for K2CO3
i think a beaker would be a better alternative when cracking out the acid so that it is easier to wash and less acid stays on the sides of the flask
vibzz lab lmao then just use like 10 disposable glasses
The potassium permanganate is NOT a catalyst... it's consumed by the reaction. Terminology is important.
Good job!
Yes it's an oxidising agent
How can we add KMNO4 through reflux condenser??
Res Sir We are using benzaldihyde in process but some unreached in reaction how can remove its.
What pH are you getting when adding the Na2CO3?
Very nice! What an interesting substance. Perhaps now you could make phenol.

Tq sir
Thank you sir nice explanation 👍
Why sodium carbonate is adding to belzaldehyde???
🔥🔥good video
What are the references?
👍
