Abstract: The invention relates to a vertical cylinder reactor (1) for carrying out gas-liquid, liquid-liquid or gas-liquid-solid chemical reactions. Said reactor comprises a nozzle (2) which is arranged in the upper portion of the reactor and which is directed downwards and by way of which the educts and the reaction mixture are supplied. The reactor further comprises a discharge (3), preferably in the lower portion of the reactor, through which the reaction mixture can be re-fed to the nozzle (2) via an exterior circuit by way of a pump (P). A concentric guide tube is arranged in the reactor which substantially extends across the entire length of the reactor (1) except the reactor ends. Said guide tube has a cross-sectional area in the range of a tenth to half of the cross-sectional area of the reactor (1). The nozzle is arranged above the upper end of the guide tube (4), preferably in a distance of an eighth to a full cross-sectional area of the guide tube or it dips into the guide tube (4) in a depth of up to several cross-sectional areas of the guide tube. A heat exchanger is integrated into the annulus, especially a heat exchanger with heat exchanger tubes (6) welded between bottoms (6). Said tubes are preferably arranged parallel to the guide tube.

Abstract: Production of alkylaromatic compounds (I), by reacting 3-30C olefins (II) (or alcohols forming (II) under the reaction conditions) with aromatic hydrocarbons (III) in presence of an alkylation catalyst (IV), is carried out in a cascade of at least two reactors each containing (IV), where at least 80 % of (III) is supplied to the first reactor of the cascade and at least 40 % of (II) is supplied after the first reactor. An independent claim is included for the preparation of alkylarylsulfonates (A), by: (1) converting a 4C olefin mixture over a metathesis catalyst to give an olefin mixture containing 2-pentene and/or 2-hexene; (2) catalytically dimerizing the 2-pentene and/or 2-hexene (optionally after isolation) to give a mixture containing 10-12C olefins, optionally separating the 10-12C olefins and separating 5-30 wt. % (based on the 10-12C olefins) of low-boiling components of the 10-12C olefins; (3) reacting the obtained 10-12C olefin mixture with (III) in presence of (IV) to give alkylaromatic compounds (I'), optionally with addition of 0-60 wt. % (based on the 10-12C olefin mixture) of linear olefins before the reaction; (4) sulfonating (I') and neutralizing to give (A), optionally with addition of 0-60 wt. % (based on (I')) of linear alkylbenzenes (provided that no mixing has been carried out in the previous step); and (5) optionally mixing the obtained (A) with optionally with addition of 0-60 wt. % (based on (A)) of linear aralkylsulfonates (provided that no mixing has been carried out either of the previous two steps); The novel feature being that the reaction in the alkylation stage (3) is carried out as for the present procedure for preparing (I).

Abstract: The disclosure involves a process for the preparation of butadiene and 1-butene. The process includes at least a first catalytic dehydrogenation of n-butane to obtain a gas stream which is followed by at least a second oxidative dehydrogenation to form a second gas stream. The second gas stream is then subjected to distillation and isomeration steps to obtain butadiene and 1-butene.

Abstract: The disclosure relates to a process for preparing butadiene. The process involves nonoxidatively catalytically dehydrogenating butane to obtain a product gas stream containing butane, 1-butene, 2-butene, butadiene, hydrogen and secondary constituents. The 1-butene and 2-butene of the product gas stream is then oxidatively dehydrogenated to give a second gas stream containing butane,2-butene, butadiene, hydrogen, steam and secondary constituents. Next, the butane,2-butene and butadiene are separated from the second gas stream and the butane and 2-butene are then separated from the butadiene product. The butane and 2-butene are then recycled into the nonoxidative catalytic dehydrogenating zone.

Abstract: In a process for preparing alkylaryl compounds by reacting a C10-14-monoolefin mixture with an aromatic hydrocarbon in the presence of an alkylation catalyst to form alkyl aromatic compounds and if appropriate subsequently sulfonating and neutralizing the resulting alkylaryl compounds, in the C10-14-monoolefins, on average, more than 0% and up to 100% of methyl branches are present in the longest carbon chain and fewer than 50% of the methyl branches are in the 2-, 3- and 4-position, calculated starting from the chain ends of the longest carbon chain.
