    摘要: In a process for dealkylating a poly-alkylated aromatic compound, a feed comprising at least one poly-alkylated aromatic compound selected from polypropylbenzene, polybutylbenzene, and polycyclohexylbenzene is introduced into a reaction zone. The feed is then contacted in the reaction zone with an acid catalyst under conditions effective to dealkylate at least a portion of the poly-alkylated aromatic compound and produce a first reaction product comprising at least one mono-alkylated aromatic compound.

    摘要: Catalysts and catalytic processes for the synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, which are carried out in a diluent or in the absence of a diluent. In an aspect, ethylene and CO2 can be contacted with a Group 8-11 transition metal precursor compound or a Group 8-11 transition metal metalalactone compound in the presence of a metal-treated chemically-modified solid oxide (MT-CMSO) or a metal-treated solid oxide (MT-SO), to form a metal acrylate. As the catalytic activity wanes in either the presence or absence of a diluent, pressure cycling—that is, pressurizing the reaction system with CO2 and an olefin such as ethylene for a time period, releasing the pressure, then re-pressurizing with CO2 and ethylene—can rejuvenate the catalyst and restore its declining catalytic activity.

    摘要: In a process for producing phenol, benzene is hydroalkylated with hydrogen in the presence of a catalyst under conditions effective to produce a hydroalkylation reaction product comprising cyclohexylbenzene and cyclohexane. At least a portion of the cyclohexane from said hydroalkylation reaction product is then dehydrogenated to produce a dehydrogenation effluent comprising benzene, toluene and hydrogen. At least a portion of the dehydrogenation effluent is washed with a benzene-containing stream to transfer at least a portion of the toluene from the dehydrogenation effluent to the benzene-containing stream.

    摘要: A method for the oxidative coupling of hydrocarbons, such as the oxidative coupling of methane to toluene, includes providing an oxidative catalyst inside a reactor, and carrying out the oxidative coupling reaction under a set of reaction conditions. The oxidative catalyst includes (A) at least one element selected from the group consisting of the Lanthanoid group, Mg, Ca, and the elements of Group 4 of the periodic table (Ti, Zr, and Hf); (B) at least one element selected from the group consisting of the Group 1 elements of Li, Na, K, Rb, Cs, and the elements of Group 3 (including La and Ac) and Groups 5-15 of the periodic table; (C) at least one element selected from the group consisting of the Group 1 elements of Li, Na, K, Rb, Cs, and the elements Ca, Sr, and Ba; and (D) oxygen.
