Can K2Cr2O7 oxidize salicylic acid? I'm studying chemistry lab and I've done the experiment and the result show that it can't but I'm not sure. The others phenolic compound that I have tested show positive result, for example , alpha-naphthol. Why can't salicylic be oxidized? Please explain. Thanks for your reply.

I can't see why salicylic acid couldn't be oxidized. It can however merely trap an O2, but I don't know if that has anything to do with being able to get oxidized. :S How many tests have you performed?

it can be oxidized...add permanganic anhydride:)

I didn't says that it can't be oxidized at all but I wonder what if I mix dichromate and salicylic acid. Can dichromate oxidize salicylic acid? (I think dichromate is not as strong oxidizer as permanganic anhydride so can it oxidize?) thank you for reply

Lol. I must say that I'd be surprised if it didn't oxidize right away with Mn2O7. That's some wacky stuff.

 

"I wonder what if I mix dichromate and salicylic acid. Can dichromate oxidize salicylic acid?"

 

I can't see why, as it is quite a powerful oxidizer. But on the other hand, if you could oxidize 1-naphthol yet you had a negative result with salicylic acid... Hmm, odd. :I

yes, yes it is wacky. dark green viscous volatile liquid that slowly decomposes to form ozone. yup, thats some wacky stuff. explodes really easy. oxidation potential is really high.

 

i would think that 2-hydroxybenzoic acid could be attacked in the 3,4,5, and 6 regions, more likely the 4 and 5 positions

Hello

 

Can anybody tell me what the products would be of salicylic acid being oxidized by either hydrogen peroxide or oxone?

 

Thank you for your help

 

 

Ozone + salicylic acid ---> ???

 

Hydrogen peroxide + salicylic acid ---> ???

saylic acid plus a phenol atom is aspirin if that helps :-S

the typical method in labs is KMnO4 and H2SO4, potassium diChromate is also good, just more expensive and less often used for that reason
