ascorbic acid and sodium benzoate

Can they react?

Stuped question, but I'm confused!

Well, try some guesses in your head.  You probably don't mean mixed dry, but do you mean in aqueous solution, or do you mean one of them reacted with organic reagents, and then reacted with the other?
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

I read that thay can react and that we can get C6H6?! But for me it's sound totally like nonsense... Am I wrong?

In soft drinks?

Oh, that old benzene reaction in soft drinks, yeah, I read that on the Usenet a couple of years ago.  See here on wikipedia: http://en.wikipedia.org/wiki/Benzene_in_soft_drinks#Formation_in_soft_drinks
The chemistry quoted by most supporters of the phenomena is a little hard to believe, the mechanism a little lacking.  The concentrations produced are also likely very small.  But you can check the references in the wikipedia article for more technical information.

But then, there's a similar point of view associated with aspertame, people claim it converts to methanol, without regard for the very low amounts the mechanism would lead to.  Coupled with bad science in the reporting of the symptoms, and the flashing big fonts people use in supporting websites, the whole concept becomes a muddled mass of opinions.
