Abstract

A process for the preparation of a detergent product comprising an alkylaryl compound in which the aryl nucleus is monocyclic, and the alkyl radical in the aryl nucleus contains 9 to about 15 carbon atoms, and which process comprises the preparation of an olefinic derivative having from 9 to about 15 carbon atoms per molecule, the alkylation of an aromatic compound selected from the group consisting of benzene, toluene, xylene, ethylbenzene, methylethylbenzene, phenol, diethylbenzene and mononitrobenzene, with said derivative olefinic action, to form the monoalcohilate of said aromatic compound, and the conversion of said monoalcohilate into a detergent product, by introducing a hydrophilic group into the aryl nucleus of the monoalkohilate, characterized by the improvements comprising preparing said olefinic derivative by separation of a straight chain paraffin a hydrocarbon mixture containing said rectilinear chain paraffin mixed with its branched chain isomers, and converting said rectilinear chain paraffin, thus separated from its branched chain isomers, into an olefinic derivative, retaining the chain structure rectilinear, by dehydrogenation of straight-chain paraffin to straight-chain monoolefin, in contact with a non-acid dehydrogenation catalyst comprising a neutral oxide of a group vi element, or a metal, sulfur or oxide of a group viii element of the periodic table, deposited on an inert support free of acidic ions, at high temperatures and pressures, in the presence of hydrogen.
