Sterically hindered cyclic diamines: BASFRecent Research Landscape

Competitive gas separation is limited by poor selectivity and high energy requirements for solvent regeneration. These innovations utilize specific molecular architectures to preferentially capture hydrogen sulfide while minimizing co-absorption of carbon dioxide.

What technical problems is BASF addressing in Sterically hindered cyclic diamines?

Industrial fluid chemical contamination

(19)evidences

Unwanted byproduct formation and mechanical degradation of adsorbents reduce process yield. Minimizing these losses increases operational uptime and chemical purity.

Inadequate hydrogen sulfide selectivity

(9)evidences

Current absorption agents lack the necessary specificity to differentiate between hydrogen sulfide and other acid gas components. Improving selectivity prevents wasteful processing of non-target gases and increases overall capture capacity.
