摘要： The invention relates to a method for producing alkyl aromatic compounds by reacting C3-30 olefins or alcohols, from which C3-30 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 consisting of at least two reactors, whereby each of the reactors contain the alkylation catalyst, at least 80 % of the aromatic hydrocarbon is fed into the first reactor of the reactor cascade, and at least 40 % of the olefins are fed in an intermediate manner after the first reactor.

摘要： Disclosed is a process for the preparation of alkanoate esters of hydroxybenzenesulfonic acids and salts thereof by the steps of (1) contacting or reacting phenol with an alkanoic acid in the presence of trifluoroacetic acid (TFA) and trifluoroacetic anhydride (TFAA) to produce an aryl alkanaoate ester and (2) contacting the reaction mixture of step (1) with a sulfonating agent to convert the aryl alkanoate ester to an alkanaoate ester of hydroxybenzenesulfonic acid. The process provides the economic advantage inherent in using the product of esterification of step (1) without isolation in the sulfonation of step (2).

摘要： Cleaning compositions, especially laundry detergents and the like comprising: (i) modified alkylarylsulfonate surfactants, e.g., modified alkylbenzenesulfonates, which are the product of particular processes and (ii) cleaning adjuncts such as enzymes and bleaches. Processes for making the cleaning products, including processes comprising vinylidene olefin production, alkylation of arenes, sulfonation and domestic cleaning product formulation. VO production is used to introduce particular limited branching into an alpha-olefinic feedstock which, converted to dimer form, has from about 10 to about 16, preferably from about 12 to about 14 carbon atoms. Preferred processes maximize the amount of vinylidene olefin useful for detergent manufacture, and minimize deep internal olefin production. Further, an alkylation step, preferably having an internal isomer selectivity of from 0 to no more than about 40 is used, in which the VO monoalkylates arenes such as benzene, in presence of an alkylation catalyst preferably comprising an at least partially crystalline, porous zeolite-containing solid, the zeolite being at least partially acidic and having intermediate pore size. Preferred alkylation catalysts include at least partially dealuminized acidic mordenites.
