Sorbitan

Sorbitan is produced by the dehydration of sorbitol and is an intermediate in the conversion of sorbitol to isosorbide. The dehydration reaction usually produces sorbitan as a mixture of five- and six-membered cyclic ethers (1,4-anhydrosorbitol, 1,5-anhydrosorbitol and 1,4,3,6-dianhydrosorbitol) [3] with the five-membered 1,4-anhydrosorbitol form being the dominate product.

an introduction to acid anhydrides

Ethanoic anhydride can't be said to dissolve in water because it reacts with it to give ethanoic acid. There is no such thing as an aqueous solution of ethanoic anhydride. Boiling point. Ethanoic anhydride boils at 140C. This is because it is a fairly big polar molecule and so has both van der Waals dispersion forces and dipole-dipole attractions.
