TL;DR: In this article, the authors provide a composition for an organic electroluminescence element with which a stable and homogeneous amorphous film can be obtained by a wet filming method.
Abstract: PROBLEM TO BE SOLVED: To provide a composition for an organic electroluminescence element with which a stable and homogeneous amorphous film can be obtained by a wet filming method. SOLUTION: Disclosed is the composition for the organic electroluminescence element which contains a charge transport material for wet filming represented by formula (I) and a solvent of ≥180°C in boiling point. In the formula (I), Q is an atom of C or N, Ar 1 to Ar 3 are each an aromatic hydrocarbon group, Ar 4 is an aromatic hydrocarbon group or an aromatic heterocyclic group, and J 1 is a direct bond, an aromatic hydrocarbon group or an aromatic heterocyclic group.

TL;DR: In this paper, it was shown that heavy petroleum oils, such as vacuum resids and heavy fractions of tar sands and shale oil, are partially converted to more volatile hydrocarbons by mixing with light aromatic polymers and treatment of the mixture with a transalkylation catalyst such as aluminum chloride.
Abstract: Heavy petroleum oils, such as vacuum resids and heavy fractions of tar sands and shale oil, are partially converted to more volatile hydrocarbons by mixing with light aromatic hydrocarbons and treatment of the mixture with a transalkylation catalyst, for example a Friedel-Crafts catalyst such as aluminum chloride. It is believed that the conversion is essentially a transalkylation, i.e. the resid undergoes dealkylation with concurrent alkylation of the light aromatic hydrocarbon.

TL;DR: In this article, a chalcogen-containing aromatic compound and an organic electronic device using it were presented. But they did not specify the properties of the device and the compound.
Abstract: Provided are a novel chalcogen-containing aromatic compound and an organic electronic device using the compound. This compound is a chalcogen-containing aromatic compound represented by the formula (1). Among the organic electronic devices each using this chalcogen-containing aromatic compound are an organic EL device, an organic TFT device, a photovoltaic device, and the like. In the formula (1): X represents oxygen, sulfur, or selenium; A represents an alkyl group, a cycloalkyl group, an alkenyl group, an alkynyl group, an aromatic hydrocarbon group, an aromatic heterocyclic group, or an amino group; and n's each independently represent an integer of 0 to 2, provided that a sum of two n's is 1 to 4.

TL;DR: In this paper, a gaseous olefin and a monocyclic aromatic hydrocarbon from crude oil is directly prepared by hydrogenating the crude oil in the presence of a hydrogenation catalyst followed by thermal cracking.
Abstract: PURPOSE:To directly prepare a gaseous olefin and a monocyclic aromatic hydrocarbon from crude oil by hydrogenating the crude oil in the presence of a hydrogenation catalyst followed by thermal cracking. CONSTITUTION:Crude oil is hydrogenated in the presence of hydrogen and a hydrogenation catalyst. Then the hydrogenated crude oil is thermally cracked. Crude oil pref. used includes those of low metal and sulfur content and high paraffinic hydrocarbon content, such as Minas, Cinta, Djatibarang or Tachin oil, and those of low asphaltene and sulfur content and high light fraction content. such as Algena, Attaka, Seria or Libya oil. As the hydrogenation catalyst, it is pef. to use one contg. at least one metal selected from Group VIb metals and at least one metal selected from Group VIII metals, such as one comprising combination of metals, e.g., Ni/Mo, Co/Mo or Ni/W, supported on an inorg. carrier.

TL;DR: Ketocarbenoid was generated by the reaction of ω,ω-dibromoacetophenone with copper in aromatic hydrocarbon, and was trapped by cycloaddition to olefins.
Abstract: Ketocarbenoid was generated by the reaction of ω,ω-dibromoacetophenone with copper in aromatic hydrocarbon, and was trapped by cycloaddition to olefins. This is the first example of cyclopropanation of olefins by formally divalent carbon intermediate without use of diazoketones.
