Latest Patents

Baek’s listed patents describe two approaches to preparing heterogeneous linear carbonates.

- Method of Preparing Heterogeneous Linear Carbonate Using Catalyst Having Excellent Solubility. This method performs a transesterification reaction of dimethyl carbonate and ethanol using a catalyst selected from lithium methoxide, lithium ethoxide, sodium methoxide, sodium hydroxide, or a mixture of these substances. The catalyst is introduced dissolved in a sulfoxide-based solvent.

- Method of Preparing Heterogeneous Linear Carbonate Using Amine-Based Compound Catalyst. This method uses an amine-based catalyst with a boiling point of at least 150°C during the transesterification of dimethyl carbonate and ethanol.
