I have to STRONGLY disagree with you on this one AWK
Sulfuric ether as symonym of diethyl ether is commonly used in chemical technology, pharmacy
and so on
If there was, then sulfuric acid would not possibly be a catalyst in the dehydration reaction because it would be consumed
Catalyst can be consumed in one step of multistep rraction, then restored before the end of reaction as in the ether synthesis.
C2H5OH + H2SO4 = C2H5OSO3H
C2H5OSO3H +C2H5OH = H2SO4(l) + C2H5OC2H5(g) + H2O(g)
Yes, but that's when the ether contains the sulfur atom. In the case of diethyl ether, there is absolutely no sulfur atom in it. In the intermediate, yes, it does exist, but not in the final product and that is what the original poster was asking about. I think there's just some confusion on what is being asked.
The intermediate in the reaction is a sulfuric ether, but not the final product. (I also mentioned in my previous post that "A catalyst cannot be consumed in a reaction without being regenerated." In this case, the sulfuric acid is regenerated so it is indeed a catalyst in the production of diethyl ether).
EDIT: Okay, I do have to admit that I was incorrect. Apparently sulfuric ether is a commonly used synonym for diethyl ether. Either way, I think it is a horribly incorrect way to describe diethyl ether since the name would denote the presence of a sulfur atom which diethyl ether does not contain. It's an appropriate term to describe how the ether was synthesized, and I think that it can cause confusion especially if a different ether is also generated by sulfuric acid.
