Polyaniline composite, method for producing same, and composition

In a reaction in which a boron trifluoride complex is used as a catalyst, the expensive and harmful boron trifluoride complex is separated from a reaction mixture containing the boron trifluoride complex by separating the boron trifluoride complex present in the reaction mixture by using a saturated hydrocarbon-based solvent.

Recovery method and recycling method for boron trifluoride complex

Lubricating oil for non-stage transmission

A process for producing xylene from toluene or benzene by the use as a catalyst of a fluorine-containing crystalline aluminosilicate or a fluorine-containing crystalline borosilicate. The specified crystalline silicate catalyst increases the conversion of toluene or benzen and the selectivity of xylene. This catalyst can keep its high catalytic activity for long periods of time during the reaction.

Process for the production of xylene

A process for the production of para-xylene is described, comprising methylating benzene or toluene in the presence of a catalyst composed mainly of (A) crystalline borosilicate and (B) a compound containing at least one element selected from the group consisting of Group IIa elements of the Periodic Table, Group IIIa elements of the Periodic Table, silicon, and phosphorus. The process of the invention enables to produce para-xylene in a high selectivity and a high yield. Since the life of the catalyst as used herein is very long, the process of the invention can be performed continuously for long periods of time while maintaining its high catalytic activity.
