Usage

Description

1,3-Dioxan-2-one, also known as cyclic trimethylene carbonate (TMC), is a heterocyclic organic compound that can be polymerized to form amorphous polymers with low glass transition temperatures. It is characterized by its ability to be copolymerized with other lactone monomers, resulting in materials with tunable physical and chemical properties.

Uses

Used in Biomedical Applications:
1,3-Dioxan-2-one is used as a key component in the production of biodegradable composites for bone tissue engineering and drug delivery. The resulting PTMC-based polymers degrade in vivo through an enzymatic surface erosion mechanism without releasing acidic degradation products, making them suitable for use in biomedical applications.
Used in Polymer Industry:
1,3-Dioxan-2-one is used as a monomer for the synthesis of amorphous polymers with low glass transition temperatures. These polymers can be copolymerized with other lactone monomers to create materials with tunable properties, such as flexibility and elasticity. After cross-linking, a (co-)polymer network is obtained with properties similar to those of polydimethylsiloxane (PDMS) rubber, making it useful for various applications in the polymer industry.

Production Methods

The direct polymerization method is a continuous esterification reactionOpen-loop polymerization includes three reaction steps: oligomerization, depolymerization and ring opening, which can achieve precise control of the polymerization reaction

PROCESS FOR THE SYNTHESIS OF ISOCYANATE-FREE OMEGA-HYDROXY-URETHANES, ALPHA-OMEGA-DIURETHANES AND OLIGO (POLY)URETHANES

The synthesis of omega-hydroxyalkyl-urethanes, and of alfa-omega-diurethanes is reported which includes the reaction of diols with urea in presence of catalysts based on Ce at temperatures between 125 and 170°C over 4-8 h reaction time. A process for the production of oligomers of omega-hydroxyalkyl-urethanes is also reported based on the reaction of urea with diols in presence of Ce or Zr catalysts or Ce mixed oxides at 125-170°C over 4-20 h.

Ultrasound-assisted synthesis of a stable Co(II) coordination polymer as heterogeneous catalyst for CO2 transformation

A stable benzimidazole-containing Co(II) coordination polymer namely [Co(L)0.5(oba)]n (1) (H2oba = 4,4′-oxybis(benzoate), L = 1,6-bis(5,6-dimethylbenzimidazolyl) hexane) was successfully synthesized by ultrasonic technique under mild conditions. In especial, the effects of initial reagent concentration, irradiation time and ultrasonic power on the morphology and size of micron scale 1 were discussed in detail. Micron scale 1 appeared exceptional solvent and pH stabilities. Further, as a heterogeneous Lewis catalyst, 1 exhibited a highly activity and recyclability for CO2 transformation by cycloaddition with epoxide under room temperature.

Rational Design of Cobalt Complexes Based on the trans Effect of Hybrid Ligands and Evaluation of their Catalytic Activity in the Cycloaddition of Carbon Dioxide with Epoxide

A series of cobalt complexes are presented as effective catalysts for the synthesis of cyclic carbonates from epoxides and CO2. The catalytic potentials of the cobalt complexes, in combination with tetrabutylammonium bromide, have been demonstrated to solve some challenges in the synthesis of cyclic carbonates, including the room-temperature conversion of terminal epoxides and activation-challenging substrates such as internal epoxides and fatty acid derived epoxides. A key factor in the success of the strategy is the use of cobalt complexes that are prepared on the basis of the trans effect of hybrid ligands. The trans effect between N-heterocyclic carbenes and acetylacetone has been proved by a number of spectroscopic measurements, including UV-vis, ESI-MS, EPR, and in situ FT-IR and by DFT calculations; these support the notion that acetylacetone prefers to dissociate from the cobalt center, which will result in one coordination site for the activation of a substrate molecule at the cobalt atom and thus give rise to high reactivity.
