bis(chloromethyl)ether from hexamine hydrolysis?

derk19 - 18-5-2020 at 09:56

Hi there,
A while ago I made some methylamine.hcl through hydrolysis of hexamine into formaldehyde and ammonium chloride with 30% hcl.
More recently, I read that formaldehyde and hcl should never be in contact because highly toxic and carcinogenic bis(chloromethyl)ether can form.

Is this a real danger in this particular synthesis?
I don't have any symptoms, but I am afraid I might have been exposed to this carcinogen.

I think it shouldn't be a problem when you add the acid slowly, here is a comment about it from erowid:

"Not when I did it. NO Formaldehyde smell was ever noticed. In fact, the mixing of Hexamine with HCl, if done *slowly* is fairly docile with no real smell elicited. However when you heat the filtered mixture on the stove, it *definitely* stinks to high heaven, but the smell at first is more like an *isocyanate*. "

I wouldn't worry, as BCME is toxic due to it's reactivity, so it will react with the amine species in solution. It will, at worst, and if it forms, exist only transiently.

Okay thanks, that's reassuring.

Now I know that if I get lung cancer it will be because of the smoking.
