Glycol cyclic

Polyethers are also products of commercial importance. Ethers can be formed by thermal dehydration, as shown for the formation of dipropylene glycol from propylene glycol. Cyclic ethers can form by elimination of water from di- or tripropylene glycol. [Pg.366]

Corresponding vinyl ethers are formed only to a minor extent. Their formation can, however, be favored by diluting the reaction mixture with an inert solvent [2]. With glycols, cyclic acetals are obtained, e. g., dioxolanes from 1,2-glycols and 1,3-dioxanes from 1,3-glycols [97]. This reaction has been claimed as an alternative to the Wacker route producing acetaldehyde when it is carried out in the presence of suitable oxidants. [Pg.1333]
