Biomass‐Based H 2 S Scavengers: Michael Acceptors

Michael acceptors derived from biomass resources, such as carbohydrates, have been synthesized and their H 2 S scavenging properties studied. The most promising candidates were compared with the commercial H 2 S scavenger MEA‐triazine by studying the aqueous phase scavenging reactions using in situ Raman spectroscopy and the gas–liquid reactions were evaluated in a flow setup. Based on cost and scavenging efficiency considerations, the industrially most promising candidates were submitted to ecotoxicity studies. We have found three families of Michael acceptors, which are readily available and can be tailor‐made to serve as sulfide scavengers under different conditions.
