This study investigates the feasibility of using biobased fumaric acid for the synthesis of FAEs and identifies the optimal conditions for DMF synthesis. The use of biobased fumaric acid as a renewable resource can have a positive impact on the sustainable synthesis of FAEs.
Fumaric acid esters (FAEs) such as monomethyl fumarate (MMF) and dimethyl fumarate (DMF) are active pharmaceutical ingredients (API) used in the treatment of psoriasis and multiple sclerosis. The present work investigates the use of biobased fumaric acid obtained via submerged fermentation under fixed conditions for the production of FAEs. The effect of time, temperature, and sulphuric acid as a catalyzer on the conversion of fumaric acid to FAEs was elucidated. The optimal conditions for DMF synthesis were identified, using response surface methodology, to be 111 min incubation using 9.7% (v/v) sulphuric acid concentration at 98 degrees C. The use of biobased fumaric acid allows the use of renewable resources as the primary feedstock for the synthesis of FAEs in place of depleting petroleum resources. This value addition can have a positive impact on the techno-economic feasibility of a process towards bioproduction of fumaric acid, as well as contribute to rendering the synthesis of an API sustainable.
