摘要： Provided is a process in which a cyclobutanediol compound having a high cis:trans ratio can be stably obtained. The cyclobutanediol compound having a cis:trans ratio of 1.5:1 to 5000:1 is produced by using at least one compound selected from a group consisting of a cyclobutanedione compound, a cyclobutane ketol compound, and a cyclobutanediol compound as a raw material, and performing a catalytic hydrogenation reaction and an isomerization reaction in the cyclobutanediol compound in a solid phase state in the presence of a metal catalyst without adding a solvent.

摘要： There is provided a novel ionic composite material that can be molded into various shapes using lignin sulfonic acid as one of raw materials thereof, and having flexibility and elasticity, to significantly improve the strength and toughness and impart complete biodegradability thereto. It was found that a combination of ε-polylysine (ε-PL) which is a cationic polymer that is produced by microorganisms and lignin sulfonic acid exhibits excellent strength and toughness. In addition, ε-PL used in this technology is a biodegradable polymer that is completely degraded by microorganisms and the like in the environment. Since lignin sulfonic acid is also a biodegradable polymer, it is thought that a complex in which ε-PL and lignin sulfonic acid are mixed in this technology will exhibit complete biodegradability, and more applications thereof can be expected when utilizing the strength, durability, and biodegradability thereof in addition to the improved strength and toughness.

摘要： An object is to provide an azoline ring-containing compound which achieves characteristics required for an organic EL element, such as a driving voltage, a quantum efficiency, and element lifetime in a well-balanced manner, and particularly can obtain a high quantum efficiency, for example, in a case where the azoline ring-containing compound is used for the organic EL element. The above object is achieved by an azoline ring-containing compound represented by the following general formula (1). In formula (1), φ represents an m-valent group derived from an aromatic hydrocarbon having 6 to 40 carbon atoms or the like, Y represents —O—, —S—, or >N—Ar, R1 to R5 each represent a hydrogen atom or an alkyl having 1 to 4 carbon atoms, and L represents a phenylene group or the like.
