Abstract: An absorbent for the selective removal of hydrogen sulfide from a fluid stream comprising carbon dioxide and hydrogen sulfide, wherein the absorbent contains an aqueous solution, comprising: a) an amine or a mixture of amines of the general formula (I) wherein R1 is C1-C5-alkyl; R2 is C1-C5-alkyl; R3 is selected from hydrogen and C1-C5-alkyl; x is an integer from 2 to 10; and b) an ether or a mixture of ethers of the general formula (II): R4—[O—CH2—CH2]y—OH; wherein R4 is C1-C5-alkyl; and y is an integer from 2 to 10; wherein R1 and R4 are identical; wherein the mass ratio of b) to a) is from 0.08 to 0.5. The absorbent is suitable for the selective removal of hydrogen sulfide from a fluid stream comprising carbon dioxide and hydrogen sulfide. The absorbent has a reduced tendency for phase separation at temperatures falling within the usual range of regeneration temperatures for the aqueous amine mixtures and is easily obtainable.

Abstract: The invention relates to a process for the production of 1,6-difunctionalized hexane derivatives from 1,3-diunsaturated hydrocarbons, preferably butadiene, wherein a hydroformylation with carbon monoxide and hydrogen is performed in the presence of an at least dihydric alkanol and during the hydroformylation the temperature is increased. The reaction yields the acetals of the 1,6-hexanedial derivatives which are isolated and further reacted to obtain the desired 1,6-difunctionalized hexane derivatives, in particular 1,6-hexanediamine, 1,6-hexanediol and adipic acid.

Abstract: A process for selectively separating H2S from a gas mixture which also comprises CO2 is disclosed. A stream of the gas mixture is contacted with an absorbent solution comprising one or more amines, alkanolamines, hindered alkanolamines, capped alkanolamines, or mixtures thereof. The H2S/CO2 selectivity of the absorbent solution is preferably greater than about 4.0 for an acid gas loading [mol(CO2+H2S)/mol(amine)] between about 0.2 and about 0.6, and is achieved by reducing pH of the absorbent solution.
