Phthalic acid from naphthalene?
Hello everyone.
I've decided to synthesize luminol and luminol based dye derivatives, however, I am currently stuck at the production of phthalic acid.
I've been UTFSE but I don't see much info on an amateur way to synthesize phthalic acid. The method that really interests me is the use of KMnO4 to
oxidize naphthalene to phthalic acid and producing CO2 as a byproduct.
That's pretty much all I know about the procedure, so does anyone know any more specific information about the reaction, such as environmental
conditions, aqueous or non-polar solvents, temperature etc?
I apologize if this question was answered in some other thread on the site I could not find such threads.
Thank You ......

Alternate routes to phthalic acid production are explored in the following YouTube links. The starting points are either o-xylene or pvc gloves.
Hope its useful to you.

Permanganate oxidation of naphthalene
I know those videos they are a good source of information when I'm doing research.
Thanks triplepoint, but I was specifically asking for information pertaining to the oxidation of naphthalene, by permanganate ions, to yield phthalic
acid, such as the environmental conditions at which the reaction take place, the solvents used if any, the temperature of the reaction vessel and
purification methods of the products etc. So far I can only find vague references to the process and no truly meaningful information except for the
fact that the process produces phthalic acid and that it is possible for over oxidation of the products.
I am trying to find more specific information leading along the lines of the information above if anyone else would like to help as well.
Thank You ......

Then just find the reference for a preparative reaction and follow the procedure.
By UTFSE you would get lots of previous discussions on this topic:

Please open threads with no references only in the Beginnings section - after all, that's why we have this section (see the forum guidelines).
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

Thank You
Thank you very much Nicodem.
I saw one or two of these threads before but one is very new to me. I never saw it while using the search engine. Sorry I'm still kinda getting used
to the forum rules.
Thank You ......
