    摘要: Highly selective oxidative coupling of aromatic methyl groups, such as coupling toluene to DPE, is effected under mild, liquid phase conditions with a peroxodisulfate without expensive metal ion catalysts, in presence of substantial amounts, preferably equimolar, of methyl, ethyl or benzyl substituted quaternary ammonium salts. A continuous process is possible by electrolytic regeneration of the spent oxidant.

    摘要: A hydrocarbon phase separated from a hydrocarbon conversion process is solvent extracted with anhydrous liquid HF to separate metal pentafluoride which is carried over into the hydrocarbon phase. The extract of HF and metal fluoride is then combined with the catalyst phase (HF and metal pentafluoride) and stripped with hydrogen to reduce the molar ratio of HF to metal pentafluoride to the level that HF + metal pentafluoride catalyst is utilized in the hydrocarbon conversion process. The metal pentafluoride is TaF.sub.5 and/or NbF.sub.5 and the hydrocarbon conversion may involve isomerization, alkylation with olefins and reactions of a paraffin with another paraffin.

    摘要: A unitary reactor system for the alkylation of benzene with olefins. The hydrocarbon reactants are sprayed horizontally from a plurality of openings in a number of vertical conduits which extend upward into a lower portion of the vessel. The conduits are surrounded by a vertical reaction tube having a circular catalyst inlet at its bottom end and which contains a mixing means located above the conduits. A hydrocarbon phase is retained in the upper portion of the vessel and an acid phase surrounds the reaction tube, with the interface of the two liquid phases being maintained above the open upper end of the reaction tube.

    摘要: OLEFINS AND ISOPARAFFINS ARE ALKYLATED IN THE PRESENCE OF AN HF CATALYST. THE REACTOR EFFLUENT IS PASSED TO A SETTLING ZONE. THE HYDROCARBON PHASE IS FRACTIONATED TO RECOVER AN ALKYLATE PRODUCT. THE ACID PHASE IS RECYCLED TO THE REACTOR. A PORTION OF THE RECYCLED ACID IS PASSED TO A PURIFICATION COLUMN FOR REMOVAL OF ACID SOLUBLE OIL. STRIPPING VAPOR IS INTRODUCED INTO THE PURIFICATION COLUMN BOTH ABOVE AND BELOW THE SURFACE OF SAID SOLUBLE OIL ACCUMULATED THEREIN.

    摘要: An apparatus for the catalytic conversion of a hydrocarbon stream with a mineral acid catalyst comprising a vessel divided into an upper and lower chamber by an imperforate plate. The imperforate plate has a plurality of standpipe means connected thereto whereby hydrocarbon can pass into the upper chamber from hydrocarbon inlet means located in the lower chamber. A perforated plate is located in the upper chamber above the imperforate plate having flow guide conduits axially aligned above each of the standpipe means. A catalyst inlet means is located intermediate the imperforate and perforate plates and an emulsion outlet is located in the upper chamber. The flow guide conduits serve to promote eduction of acid-catalyst into the flow guide conduits by a high velocity hydrocarbon stream emitted from openings in said standpipe means, and to contain and confine the hydrocarbon stream and prevent contact of a resulting acidhydrocarbon emulsion with previously formed emulsion until the hydrocarbons and acid are thoroughly mixed and the hydrocarbons at least partially reacted.
