摘要： The invention relates to a process for the separation cf various dialkyl multinuclear aromatic compounds from a feed stream of mixed isomers of those compounds. A shape selective adsorbent is employed resulting in a process that is more efficient than processes based upon prior separation techniques. Of special interest are combination processes involving synthesis steps followed by sorption steps using the same shape selective materials.

摘要： A process for the selective manufacture of 2,6-diisopropylnaphthalene from naphthalene advantageously combines an equilibration reactor to enhance the amount of monoisopropylnaphthalene fed to the alkylation reactor, and the use of a shape selective catalyst in the alkylation reactor, to obtain an alkylation reaction product in which the 2,6-diisopropylnaphthalene isomer comprises greater than 39 mole percent of the total diisopropylnaphthalene obtained. Further, this combination of reaction steps and conditions produces a reaction product in which the ratio of 2,6-diisopropylnaphthalene to 2,7-diisopropylnaphthalene is greater than 1.0, preferably greater than 1.2. Recycled process components are fed to the equilibration reactor where they are combined with fresh naphthalene feed to provide a monoisopropylnaphthalene enriched feed to the alkylation reactor.

摘要： A process for the oxidation of pseudocumene to trimellitic acid anhydride which comprises catalytic oxidation of pseudocumene with air in the presence of acetic acid in an oxidation zone in the liquid phase and wherein the weight ratio of acetic acid to pseudocumene is in the range of about 1.0-2.5:1.0 and the catalyst comprises one or more heavy metal oxidation catalysts comprising zirconium, cobalt and manganese to provide about 0.2 to about 0.4 weight percent total metals based on pseudocumene and a source of bromine. The addition of the bromine component is controlled to provide a total of about 0.10 to about 0.30 weight percent total bromine based on pseudocumene. The total weight ratio of bromide ions to total metals ions is about 0.7 to about 2.0. The zirconium content is about 1 to about 5% and manganese content is about 14 to about 24% each by weight of the total metals. The reaction temperature is about 100.degree. C. to about 250.degree. C. The acetic acid and water of reaction are withdrawn during the last 5 to about 20% of the reaction.

摘要： A process for the oxidation of pseudocumene to trimellitic acid anhydride is disclosed which comprises catalytic oxidation of pseudocumene with air in the presence of acetic acid in an oxidation zone in the liquid phase wherein the weight ratio of acetic acid to pseudocumene is in the range of about 0.5-4.0:1.0 and the catalyst comprises one or more heavy metal oxidation catalysts comprising zirconium, cobalt, and manganese to provide about 0.1 to about 0.4 weight percent total metals based on pseudocumene and a source of bromine. The addition of the bromine component is controlled to provide a total of about 0.10 to about 0.30 weight percent total bromine based on pseudocumene. The total weight ratio of bromine ions to total metals ions is about 0.5 to about 2.0. The zirconium content is about 1 to about 5% and the manganese content is about 14 to about 60% each by weight of the total metals. The reaction temperature is about 100.degree. C. to about 250.degree. C. The acetic acid and water of reaction are withdrawn during the last 5 to about 20% of the reaction.
