The water is loosely bound to the ionic solid so it is possible to dehydrate or remove the water by heating. ...

Aldehydes can react with alcohols to form hemiacetals
... Cyclic acetals like this are more resistant to hydrolysis than acyclic ones and easier to make—they form quite readily even from ketones. Again, we have entropic factors to thank for their stability. For the formation of a cyclic acetal, two molecules go in (ketone plus diol) and two molecules come ...
