AMT MethaneSulfonate??

When I remember right, methansulfonate is the anion formed from dimethylsulfate with an amine (like AMT), a very strong alkylating agent. (Very carcinogenic)
I can hardly imagine that this alkylating agent does not form a quat salt with AMT.
In this case it surely is not active at all.
 
You are exacly right!
It´s the simple salt with methane sulfonic acid. The thing I mentioned would be called a methylsulfate salt.
BTW. I don´t think it stinks much, sulfur with ox. -2 e.g. in sulfides or mercaptanes is stinky, but sulfuric acid or DMSO (when fresh) is without much flavor.

Eh? Sulphuric acid tastes incredibly sour even when very dilute (that's a characteristic of all acids to some extent) and even very fresh DMSO produces a bitter taste in your mouth if you get some on your skin. I don't wish to be picky, but I think you meant smell, not flavour.
 
Interesting, I was under the impression that DMSO had a garlic-like smell, and at least I cannot put my nose anywhere near sulphuric acid, at any cocentration :S.
 
Fastandbulbous, you are right! I meant smell.
I´m sorry, about my English, It´s not too good, I know. It is simply not my mother language, and I am continuously looking in dictionaries but I´ll do my best to become better. Please be indulgent.
 
^ Yeah, i've heard all those stories about DMSO and it's stinking and whatever... every time I crack open the DMSO I give it a big wiff, and it never stinks.... are you sure fresh DMSO still stinks (cause I know it breaks down in light)

i have never noticed any smell with sulfuric acid. are you sure that you mean sulfuric acid (H2SO4) and not hydrogen sulfide (H2S). the latter does smell quite foul if you're not used to it ;)
 
I'm pretty sure I had sulphuric acid. It smelled like a combination of HCL and rotten eggs. I am not too good with chemistry, but does Sulphuric acid emit hydrogen sulfide as it ages or gets in contact with the air/water?

Same could be the case with DMSO, I might have been smelling degraded matter.
 
I am working with sulfuric acid regularly and I never noticed any smell at any bach of any concentration. The oxidation number +6 is the most stabile for sulfur. Maybe some certain bacteria could degrade it, but surely not sunlight or air.
The advantage of conced. H2SO4 versus conced. HCl is exactly that there is no pungent smell due to the high bp and low volatility. HCl is a gas that is dissolved in water and is so be released easily again, causing the pungent smell.

In the case of DMSO I admit to BilZOr. Only really fresh, DMSO is nearly without smell. After contact with air and/or water and/or light it becomes very fast degradated and stinks terrible. So the smell is a simple way to test the quality of DMSO.

A hydroscope is an optical instrument used to view objects far beneath the surface of water.

I think hygroscopic is the word you are looking for =D
