Title: Sunflower oil and KMnO4=?
Post by: Larus999 on April 20, 2016, 07:44:59 AM
Hello, I mixed KMnO4 and sunflower oil. Do you know, except the K2MnO4, what are the other products and why they react?
Thanks in advance!

K2MnO4 does not exist.  What do you think will happen and why?  According to forum rules, you must show an attempt to solve a problem or give your thoughts before we can help you.

From what I can google, K2MnO4 exists...

Sure it does, and it is a first product of the permanganate reduction. The reduction stops there only in alkaline solutions though.

@Burner, Good point (I had totally forgotten about this).  However, in organic chemistry potassium permanganate is typically used under acidic conditions.

@OP, Do fatty acids have any functional groups that are particularly susceptible to oxidation?
