A green synthesis approach toward large-scale production of benzalacetone via Claisen-Schmidt condensation. [PDF]

RSC Adv, 2022
A stirring-induced emulsion system enables 99% selectivity to the mono-condensation product of a Claisen–Schmidt reaction. The system showed good cyclic performance and can be easily scaled up to kilogram-level for the production of benzalacetone.
