Abstract: An absorbent for selective removal of hydrogen sulfide from a fluid stream comprises an aqueous solution comprising a) a tertiary amine; b) an aminic pH promoter selected from the compounds mentioned in the description; where the molar ratio of b) to a) is in the range from 0.05 to 1.0; and c) an acid having a pKA of less than 6 in such an amount that the pH of the aqueous solution measured at 120° C. is 7.9 to less than 8.8. Also described is a process for removing acidic gases from a fluid stream, in which the fluid stream is contacted with the absorbent. The absorbent is notable for a low regeneration energy.

Abstract: This disclosure relates to a composition comprising (a) 4,4′-methylene diphenyl diisocyanate (4,4′-MDI), and (b) at least one heterocyclic compound comprising as ring moiety at least one structure of formula (I) as defined in the description. The heterocyclic compound can suppress the formation of 4,4′-MDI dimer and thus prevent the formation of insoluble solids and extend the shelf life of 4,4′-MDI.
