Abstract: 1. A process for removing CO2 and/or H2 S from a gas containing CO2 and/or H2 S by washing the gas with an aqueous alkanolamine-containing absorption liquid and subsequently regenerating the latter, wherein the aqueous absorption liquid used contains from 3 to 60% by weight of methyldiethanolamine and from 1 to 50% by weight of monoethanolamine, processes with two absorption stages arranged in series, in which regeneration of the laden absorption liquid is carried out using two flash stages and a stripping zone, to the extent they utilize an absorption liquid containing from 0.05 to 1 mole of monoethanolamine per litre, being excluded.

Abstract: The present invention relates to a process for removing CO2 and/or H2S from CO2- and/or H2S-containing gases by scrubbing the gases with an aqueous absorption liquid containing an alkanolamine and with subsequent regeneration of the absorption liquid, in which an aqueous absorption liquid is used which contains 3 to 60% by weight of a tertiary alkanolamine and 1 to 50% by weight of a primary alkanolamine.

Abstract: The present invention relates to a process for removing CO2 and/or H2S from CO2- and/or H2S-containing gases by scrubbing the gases with an aqueous, alkanolamine-containing absorption liquid, with subsequent regeneration of the absorption liquid, in which an aqueous absorption liquid is used which contains 10 to 60% by weight of a tertiary alkanolamine and 1 to 50% by weight of a primary alkanolamine.

Abstract: A C4-hydrocarbon mixture which essentially contains n-butenes and butanes is separated by a process in which the mixture is reacted with a carboxylic acid in the presence of an acidic catalyst to form a butyl carboxylate, the reaction mixture obtained from the esterification zone is distilled to give, as the top product, a fraction containing the butanes, and, as the bottom product, a fraction containing the resulting butyl carboxylate, the butyl carboxylate is decomposed at elevated temperatures to give the carboxylic acid and n-butenes, and the mixture of n-butenes and carboxylic acid is then distilled, the n-butenes being obtained as the top product, and the carboxylic acid as the bottom product.

Abstract: In continuous gas phase oxidn. of C3H6 to acrolein (I) and/or acrylic acid (II) with heterogeneous catalyst in an oxidn. reactor, the charge gas mixt. (III) contains only inert diluent gas(es) (IIIA) in addn. to C3H6 and O2 and (pt. of) (IIIA) is sepd. from the prodn. gas mixt. and recycled to the oxidn. reactor. The novelty is that (IIIA) consists of over 85 vol. % 1-5C satd. hydrocarbon(s).

Abstract: Continuous gas phase partial oxidn. of an organic cpd. (I) with heterogeneous catalyst in an oxidn. reactor uses a charge gas mixt. contg. (I) O2 and an inert diluent gas (II), which consists partly of combustible gases (IIA). The novelty is that the (IIA) fraction of (II) in the prod. gas stream leaving the oxidn. reactor is not recycled to partial oxidn. but used in another chemical reaction.
