Which ether is formed by dehydration of propane-1,3-diol with sulfuric acid?
You could actually get a mixture of products,depending on what the concentration of the H2S04 is ; and whether it was used in excess.
If you drip propane-1,3-diol into the acid,the starting material will always be in low concentration,and this will favor intramolecular reaction leading to the cyclic dioxane (1,2-dioxycyclohexane).
If you add acid to the propane-1,3-diol. you get a mess of products ,including a little bit of the foregoing product,but also:
bis-dihydroxpropylether
1,3(di-hydroxypropoxy)propane
and various higher polymers
In some cases the diol might be oxidized to the dialdehyde or the dicarboxylic acid.
