presence of alkylsulfonates, which were identified as potential genotoxic impurities in our active pharmaceutical ingredient (API). As a result, we initiated a development effort to identify a method to remove the alkylsulfonates that would be amenable for scale-up. Herein, we report our effort toward the development of a general approach using DABCO (1,4-diazabicyclo[2.2.2]octane) to remove alkyl sulfonates

The method for producing biodiesel from microalgae using a thermo-responsive switchable solvent includes mixing a thermo-responsive switchable solvent (TSS) in a hydrophilic state with microalgae at room temperature (25° C.); maintaining the TSS-microalgae mixture in the hydrophilic state for a cell disruption time period; raising the temperature of the TSS-microalgae mixture to switch the TSS solvent to a hydrophobic state; maintaining the TSS solvent in the hydrophobic state in the presence of immobilized lipase catalyst and methanol for an extraction/reaction time period to obtain fatty acid methyl esters (FAMEs) as the oils are extracted; lowering the temperature of the TSS-microalgae mixture to switch the TSS solvent back to the hydrophilic state; and maintaining the TSS solvent in the hydrophilic state for a product separation time period. The method may further include extracting the FAMEs from the TSS-microalgae mixture with a nonpolar organic solvent to obtain the biodiesel product.
