    • A process is described for producing an alkylaromatic compound, in which a first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene are introduced into a first alkylation reaction zone comprising a first alkylation catalyst. The first alkylation reaction zone is operated under conditions effective to cause alkylation of the alkylatable aromatic compound by the alkene to produce said alkylaromatic compound, the conditions being such that the alkylatable aromatic compound is at least predominantly in the vapor phase. A first effluent comprising the alkylaromatic compound and unreacted alkylatable aromatic compound is withdrawn from the first alkylation reaction zone and at least part of the unreacted alkylatable aromatic compound is treated to remove catalyst poisons therefrom and produce a treated unreacted alkylatable aromatic stream. At least part of the unreacted alkylatable aromatic compound and a third feed comprising said alkene is introduced into a second alkylation reaction zone comprising a second alkylation catalyst. The second alkylation reaction zone is operated under conditions effective to cause alkylation of the unreacted alkylatable aromatic compound by the alkene to produce said alkylaromatic compound, the conditions being such that the alkylatable aromatic compound is at least predominantly in the liquid phase. A second effluent comprising said alkylaromatic compound is withdrawn from the second alkylation reaction zone.
    • 描述了用于生产烷基芳族化合物的方法,其中将包含可烷基化芳族化合物的第一种进料和包含烯烃的第二种进料引入到包含第一烷基化催化剂的第一烷基化反应区中。 第一烷基化反应区在有效使烷基化芳族化合物被烯烃烷基化以产生所述烷基芳族化合物的条件下运行,条件是使可烷基化芳族化合物至少主要在气相中。 包含烷基芳族化合物和未反应的可烷基化芳族化合物的第一流出物从第一烷基化反应区取出,并且处理至少部分未反应的可烷基化芳族化合物以除去其中的催化剂毒物并产生经处理的未反应的可烷基化芳族物流。 将至少部分未反应的可烷基化芳族化合物和包含所述烯烃的第三进料引入到包含第二烷基化催化剂的第二烷基化反应区中。 第二烷基化反应区在有效使得未反应的可烷基化芳族化合物被烯烃烷基化以产生所述烷基芳族化合物的条件下运行,条件是使可烷基化芳族化合物至少主要在液相中。 从第二烷基化反应区取出包含所述烷基芳族化合物的第二流出物。

    • In a method of treating a residue stream from the production of bisphenol-A, the residue stream is contacted with an aqueous solution of a base under conditions effective to hydrolyze at least part of said residue stream into acetone and phenol and produce an effluent stream. Acetone is recovered from the effluent stream to produce a phenol-containing mixed phase stream which is substantially free of acetone and which contains water and unhydrolyzed heavy organic compounds. The phenol-containing mixed phase stream is then treated with a water-immiscible organic solvent to extract phenol and unhydrolyzed heavy organic compounds into said solvent and produce an organic phase containing the solvent, phenol and unhydrolyzed heavy aromatic compounds and an aqueous phase with reduced concentrations of phenol and unhydrolyzed heavy organic compounds. At least part of the phenol and the organic solvent are subsequently recovered from the organic phase.
