    摘要: Provided are a methane-production inhibitor capable of inhibiting methane production for a long period of time, and a method for inhibiting methane production using the composition. A methane-production inhibitor composition contains one or more compounds selected from compounds represented by formula [I] as an effective ingredient, and a method for inhibiting methane production uses the composition.




    (In formula [I], X represents an —OR1 group, a hydroxyl group, or a halogen atom, Y represents an —OR2 group or an —SO2R3 group, R1 represents a benzoyl group, R2 represents a methylsulfonyl group or a chloromethylsulfonyl group, and R3 represents a chloromethyl group or a hydroxymethyl group.)

    摘要: The present invention addresses the problem of providing a novel alkoxymethyl-substituted bisphenol compound having exceptional storage stability and exceptional solvent solubility, heat resistance, and optical properties when used as a resin raw material. This problem can be solved by using an alkoxymethyl-substituted bisphenol compound represented by General Formula (1): (wherein each R independently represents an alkyl group having 1 to 4 carbon atoms).
