The present invention relates to a method for preparing hydrocarbon double acids using a cyclic hydrocarbon oxidation catalyst, wherein adipic acid and dodecanedioic acid may be produced with high yield while solving the problem of environmental pollution, the adipic acid and the dodecanedioic acid being prepared by using an oxidation reaction of a cyclohexane-cyclohexanone mixture and an oxidation reaction of a cyclododecane-cyclododecanone mixture, respectively, in the presence of a vanadium phosphate oxide-based catalyst and/or a cobalt-manganese oxide-based catalyst.

Disclosed herein are nanostructured hierarchical zeolitic materials comprising: a plurality of zeolite nanotubes, each zeolite nanotube comprising a zeolitic wall perforated by a plurality of pores, the zeolitic wall defining a single longitudinal lumen. Also disclosed herein are bolaform structure directing agents comprising: a first hydrophilic end and a second hydrophilic end with a hydrophobic core therebetween; the hydrophobic core comprising one or more aromatic rings and one or more hydrophobic alkyl groups; the one or more aromatic rings comprising a biphenyl group; the one or more hydrophobic alkyl groups each independently comprising a C.sub.10 alkyl group; and the first hydrophilic end and the second hydrophilic end each independently comprising a quinuclidinium group. Also disclosed herein are methods of making and use of the plurality of zeolite nanotubes and the bolaform structure directing agents.

A solid acid catalyst, and preparation and use thereof are provided. The catalyst contains a metal oxide carrier and at least one modifying metal component. When the catalyst is characterized by solid nuclear magnetic resonance with trimethylphosphine as the probe molecule, it exhibits a spectral peak in the range of 5 to 20 ppm. The catalyst can be used for hydrocracking reaction of non-aromatic hydrocarbons.
