I've heard them both described that way and wanted to clear it up for myself.

I followed the procedure with 441 grams of salicylic acid. I observed large temperature swings when distilling the crude phenol. I think they were
caused by further decarboxylation.
The distillation left behind salicylic acid residue. I decarboxylated the residue.
I obtained a good yield. It is not completely pure. Is phenol hard to fractionally distill?

I guess you have to be over 50 to know what Lifebuoy carbolic soap (a disinfecting soap containing phenol) smells like or how the soap factory at Port
Sunlight on the Wirral England could be detected with your nose from miles away by the smell of the soap. LOL
https://en.wikipedia.org/wiki/Lifebuoy_(soap)
Borosilicate glass:
Good temperature resistance and good thermal shock resistance but finite.
For normal, standard service typically 200-230°C, for short-term (minutes) service max 400°C
Maximum thermal shock resistance is 160°C

I redistilled my phenol through a short path condenser. I collected the fraction boiling between 179 C and 182 C. I obtained 188 grams of phenol
melting at 40 C, 62.7%. It smells like sore throat spray.
A honey-colored oil remains in the distillation flask.

This is the type of chemistry that I like. To make useful chemicals from normal everyday household items so I don't have to buy from chemical sellers

It is cheaper to order in the end as you can not compete with industrial production.
I do recommend doing this stuff as it builds skill and experience, but for practical stuff better to order in bulk, when I order stuff I do it in 500
to 1Kg quantities

I agree completely. UC's experimental approach is a model for how to learn the most from an experiment. Without the benefit of IR, NMR, etc, he
examines every possible explanation for his observations.
The single most important condition for a successful synthesis is good mixing - Nicodem

Phenol? Yeah. Phenol might not be an easy buy. Think TNT.
U.S. Agents, recently arrested a suspected terrorist, based on his purchasing Phenol.
It is a suspicious acquisition.
Why you might ask?
Because it is easily nitrated to produce Picric Acid. Salts of which, are comparable to TNT, in explosive potency.
Now, that arrest was in the U.S., where we can pretty much buy explosive precursors to our hearts content.
In Europe, governments tend to be more restrictive.
Though of course, legal penalties might be less in Europe.
In the U.S., if you do something terrible, you may be executed. Alternately, you may spend the rest of your life in prison. And, U.S. prisons, are
uniformly horrible.
Seems to me, there are patents for this process, utilizing benzoic acid as a solvent. But, perhaps I am mistaken?
