TL;DR: In this article, a light hydrocarbon is blended with a polycyclic and a monocyclic aromatic hydrocarbons and reacting in the presence of a zeolite-containing catalyst.
Abstract: PURPOSE: To efficiently obtain a hydrocarbon rich in benzene, toluene and xylene by blending a light hydrocarbon with a hydrocarbon containing a polycyclic and a monocyclic hydrocarbons and reacting in the presence of a zeolite- containing catalyst. CONSTITUTION: (A) 2-8C light hydrocarbon is blended with (B) 1-50wt.% (1-30wt.%) based on the total amounts of hydrocarbons of ≥9C hydrocarbon containing 140wt.% aromatic hydrocarbon and ≥3wt.% polycyclic aromatic hydrocarbon. Then the hydrocarbons are reacted in the presence of a catalyst containing a zeolite having ≥1 CI value to give the aimed hydrocarbon. A catalyst containing a metal such as Cu, Ag, Zn, Cd, Ga, Cr, W, Se, Te, Re, Co, Ni, Pd, Ir and Pt may be cited as the catalyst. COPYRIGHT: (C)1991,JPO&Japio

TL;DR: In this paper, a compound represented by the following general formula (1) is converted into (A) R-COOH (wherein R is an aromatic hydrocarbon group having 6 to 20 carbon atoms having no halogen atom or a carbon number having no non-halogen atom).
Abstract: Provided is a method for producing an epoxy compound from an olefin which is simple, has a high reaction rate, is excellent in production efficiency, and has a high yield. A compound represented by the following general formula (1) is converted into (A) R-COOH (wherein R is an aromatic hydrocarbon group having 6 to 20 carbon atoms having no halogen atom or a carbon number having no halogen atom). 1 to 20 represents an aliphatic hydrocarbon group), (B) hydrogen peroxide, and (C) an acid selected from the following (c1) to (c5): (C1) an acid containing phosphorus, (c2) an organic carboxylic acid having 1 to 20 carbon atoms containing halogen, (c3) R—SO 3 H (wherein R is a hydrogen atom or A hydrocarbon group having 1 to 20 carbon atoms which may be substituted with a halogen atom.), (C4) an inorganic acid containing tungsten, and (c5) an inorganic acid containing molybdenum.

TL;DR: Novel polyoxadiazoles soluble in m-cresol are disclosed in this paper, and fibers, films, coatings and molded objects made therefrom are made from 5-t-butylisophthalic acid and N,N'-aliphatic or aromatic hydrocarbon radicals (4-carboxyphthalimide).
Abstract: Novel polyoxadiazoles soluble in m-cresol are disclosed. Also fibers, films, coatings and molded objects made therefrom. The copolyoxadiazoles are prepared from 5-t-butylisophthalic acid and N,N'-aliphatic or aromatic hydrocarbon radicals (4-carboxyphthalimide), when coreacted with either terephthalic acid or isophthalic acid or a mixture of terephthalic acid and isophthalic acid.

TL;DR: In this paper, a host compound for light-emitting layers which have high excited triplet energy levels and can completely confine phosphor triplet excitons was proposed.
Abstract: The invention aims at providing host compounds for light-emitting layers which have high excited triplet energy levels and can completely confine phosphor triplet excitons. The invention relates to m-carbazolylphenyl compounds represented by the general formula (1): [Chemical formula 1] (1) wherein A is nitrogen, amino to which a substituted or unsubstituted aromatic hydrocarbon group is bonded, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted fused polycyclic aromatic group; n is an integer of 2 to 4; R1 and R2 may be the same or different and are each an arbitrary substituent; and m and o are each an integer of 0 to 4.
