| 1. | The preparation of the isomeric compound sporol involved a similar dioxolane formation.
|
| 2. | The co-monomer is typically dioxolane but ethylene oxide can also be used.
|
| 3. | Dioxolane is formed by reaction of ethylene glycol with aqueous formaldehyde over an acid catalyst.
|
| 4. | TADDOLs consist of a dioxolane ring substituted with two mutually transoid diarylhydroxymethyl ( Ar 2 COH ) groups.
|
| 5. | Trioxane and Dioxolane are polymerized using an acid catalyst, often boron trifluoride etherate, BF 3 OEt 2.
|
| 6. | The dioxolane is expanded to the 1, 3-dioxane system found in sporol at a later step in the synthesis.
|
| 7. | The use of the urea complex, which gave a water-free material, successfully gave the dioxolane as the major product.
|
| 8. | "' Dioxolane "'is a peroxide . 1, 3-Dioxolane is used as a solvent and as a comonomer in polyacetals.
|
| 9. | "' Dioxolane "'is a peroxide . 1, 3-Dioxolane is used as a solvent and as a comonomer in polyacetals.
|
| 10. | By replacing the 1, 3-dioxolane group with an appropriate ring structure, various other types of putians have been synthesized, e . g.
