A process for continuous production of C-C-monoalkanolamines by reaction of a corresponding C-C-alkylene oxide with a molar excess of ammonia (NH), wherein aqueous ammonia is employed, in the liquid phase and in the presence of an acidic cation exchanger as catalyst which contains a crosslinked copolymer comprising acidic functional groups as the carrier matrix, wherein the cation exchanger has a total exchange capacity of not less than 1.8 eq/L.

Method for producing C-Cmono alkanol amines using an acid cation exchanger as a catalyst

The present invention relates to the polyamines N,N'-diaminopropyl-2-methyl-cyclohexane-1,3-diamine and N,N&#x2032;-diaminopropyl-4-methyl-cyclohexane-1,3-diamine and mixtures thereof, to the use thereof as curing agents for epoxy resin and to a curable composition comprising epoxy resin and these polyamines. Even at low temperatures this curing agent/the corresponding curable composition cures rapidly and is early-stage water resistant and is thus especially suitable for floor coatings. The invention further relates to the curing of this composition and the cured epoxy resin obtained by curing of this composition.

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 pKof less than 6 in such an amount that the pH of the aqueous solution measured at 120&#xb0; 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.
