A method for producing adamantane includes the steps of preparing a catalytic composition including an acidic ionic liquid and a co-catalyst and subjecting a tetrahydrodicyclopentadiene-containing component to isomerization in the presence of the catalytic composition to form adamantane. The acidic ionic liquid includes aluminum chloride and a quaternary onium compound selected from the group consisting of a quaternary ammonium halide, a quaternary phosphonium halide, and a combination thereof. The co-catalyst is an oxygen-containing reagent.

The present disclosure relates to preparation of liquid salt including but not limiting to ionic liquid and applications thereof. More particularly, the present disclosure provides a process for preparing ionic liquid which comprises reacting at least one electron-pair acceptor and at least one electron-pair donor to form an adduct, and reacting the adduct with at least one electron-pair acceptor to prepare said salt. The present disclosure also provides for applications of the ionic liquid prepared in the present disclosure.

The present invention relates to the synthesis of polycyclic aromatic compounds. Compounds such as terrylene or quaterrylene may now be prepared in relatively high yield by reaction of naphthalene or perylene via Scholl-type coupling in the presence of a superacid and an oxidant in an inert solvent.

Provided is a Group 9 novel metal catalyst complex further comprising a ketone-containing cocatalyst. The metal catalyst complex is useful in generating olefins from alkanes with great efficiency. In one embodiment, provided is an iridium catalyst complex useful in the dehydrogenation of alkanes comprising a ketone-containing cocatalyst and iridium complexed with a tridentate ligand.

A process for selectively producing oligomers may comprise bringing at least one antifouling agent into contact with a first amount of at least one aluminum alkyl compound to form at least one antifouling compound comprising the structure:

##STR00001##

or its dimeric form; and feeding the at least one antifouling compound, an additional amount of the at least one aluminum alkyl compound, at least one titanate compound, and ethylene into a jet loop reactor and oligomerizing ethylene to produce one or more of 1-butene, 1-hexene, or 1-octene. One or more of the chemical groups R1, R2, and R3 may be the antifouling agent comprising the structure O((CH.sub.2).sub.nO).sub.mR4. n may be an integer of from 1 to 20. m may be an integer of from 1 to 100. R4 may be a hydrocarbyl group. In embodiments, the chemical groups R1, R2, or R3 that do not comprise the antifouling agent, if any, may be hydrocarbyl groups. The at least one titanate compound may be fed as a stream separate from the streams of the at least one antifouling compound and the additional amount of the at least one aluminum alkyl compound. The of the sum of the first amount and the additional amount of the at least one aluminum alkyl compound to the at least one titanate compound may be equal to or higher than 1.5 and equal to or lower than 3.0.

A radio access network (RAN) configured to support real-time communications over a Long-Term Evolution (LTE) connection is described herein. When a request for a data transmission is received and a real-time communication session over the LTE connection is established, the RAN utilizes the LTE connection, not a New Radio (NR) connection, for the data transmission. When a request for a further real-time communication is received and there is an active data transmission session over the NR connection, the RAN performs at least one of ceasing to allocate traffic to the NR connection for downlink or reconfiguring the data transmission session to send data over the LTE connection.

A method of controlling a hydrocarbon conversion process is described. The method involves introducing a reactant into a reaction zone containing an ionic liquid catalyst.
