Abstract

Process for adding hydrocarbons to the benzene ring of aromatic compounds by olefins in which said aromatic compounds are mainly benzene, phenol and substituted phenol derivatives, such as cresols and other alkyl phenols, phenol halides, phenolic ethers, amino phenols, aryl phenols, phenolic ethers and the like consisting essentially of carrying out the selective alkylation, through a tertiary carbon, of a hydrocarbon to the benzene ring of benzene, alkyl benzene, phenol, cresols or any other of the substituted compounds indicated above, such alkylation is carried out with an olefin of the same number of carbons as the alkylated hydrocarbon and of the same species as said hydrocarbon, with a double bond in said tertiary carbon, using a reactor equipped with good cooling, mixing and control and preferably equipped with a bubbling distributor located at the bottom, c by reacting the reaction with an acid, acid complex or metal complex in cocatalysis with a proton promoter which can be even residual humidity, carrying out such a reaction at temperature and pressure substantially constant, the atmospheric pressure being in most cases.
