In a process for the preparation of alkylaromatic compounds by reacting C-olefins, or alcohols from which C-olefins are formed under the reaction conditions, with an aromatic hydrocarbon in the presence of an alkylation catalyst, the reaction is carried out in a reactor cascade of at least two reactors, where each of the reactors comprises the alkylation catalyst, at least 80% of the aromatic hydrocarbon are fed into the first reactor of the reactor cascade, and at least 40% of the olefins are intermediately fed in after the first reactor.

Method for producing alkyl aromatic compounds

A surfactant composition includes a first surfactant, a second surfactant, and a polyalkylene glycol. The first surfactant is of the general formula R&#x2014;O&#x2014;(A)H, wherein Ris an aliphatic hydrocarbon having 10 carbon atoms, A is an alkyleneoxy group having from 2 to 5 carbon atoms, and m is a positive number. The second surfactant is of the general formula R&#x2014;O&#x2014;(B)H, wherein Ris an aliphatic hydrocarbon having from 12 to 14 carbon atoms, B is an alkyleneoxy group having from 2 to 5 carbon atoms, and n is a positive number. The polyalkylene glycol is present in the surfactant composition in an amount of from 3 to 20 parts by weight per 100 parts by weight of the surfactant composition.
