Description

一般描述

1,3-dioxolane is a heterocyclic acetal that is commonly used as a green solvent in formulations and production processes. It is also used as a reactant in organic synthesis. Long-term storage of 1,3-dioxolane forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for peroxide formation.

应用

1,3-dioxolane can be used as a solvent:      

• For the extraction of biodegradable poly(3-hydroxybutyrate) (PHB) from biomass.     
• To produce stable dispersions of multiwalled carbon nanotubes (MWCNTs) for the synthesis of modified glassy carbon electrodes.
• To synthesize copolymers (polyoxymethylene) by cationic copolymerization of 1,3,5-trioxane in the presence of maghnite-H⁺ as a catalyst.

It is also used as a reactant to prepare quasi-solid-state poly(1,3-dioxolane) electrolyte by Sc(OTf)₃ catalyzed ring-opening polymerization reactions.
