    摘要: To achieve the object of providing a new method of manufacturing 4,4"-dihydroxy-m-terphenyl, the present invention provides a method of manufacturing 4,4"-dihydroxy-m-terphenyl expressed by General Formula (4) below, characterized in that such method uses a 2-cyclohexene-1-one expressed by General Formula (1) below or 3-hydroxycyclohexane-1-one expressed by General Formula (2) below, and phenol expressed by General Formula (3) below as materials and implements Step (A), Step (B), and Step (C) below, in this order, or Step (D) and Step (C) below, in this order:

    (In the formulas, each R 2 independently represents an alkyl group, alkoxy group, aromatic hydrocarbon group, or halogen atom, while m independently indicates 0 or an integer of 1 to 4, where R 2 substitution does not occur in the third position when m is 1 or greater, and when m is 2 or greater, R 2 's may be identical or different, and R 2 substitution does not occur in two positions of the same carbon atom. In addition, R 2 and m in General Formula (1) may be identical to or different from R 2 and m in General Formula (2), respectively.)

    (In the formula, each R 1 independently represents an alkyl group, alkoxy group, aromatic hydrocarbon group, halogen atom, or hydroxyl group, while n indicates 0 or an integer of 1 to 4, where R 1 's may be identical or different when n is 2 or greater.)
    Step (A): Step to obtain a 1,1,3-trisphenol by causing the 2-cyclohexene-1-one or 3-hydroxycyclohexane-1-one and phenol to react with each other in the presence of a catalyst.
    Step (B): Step to obtain a bis(4-hydroxyphenyl)cyclohexene by causing the 1,1,3-trisphenol to undergo breakdown reaction.
    Step (C): Step to obtain a 4,4"-dihydroxy-m-terphenyl by dehydrogenating the bis(4-hydroxyphenyl)cyclohexene.
    Step (D): Step to obtain a bis(4-hydroxyphenyl)cyclohexene by causing the 2-cyclohexene-1-one or 3-hydroxycyclohexane-1-one and phenol to react with each other in the presence of a catalyst.


    (In the formula, each R 1 and n is independently the same as the corresponding items in General Formula (3), respectively, while R 2 and m are the same as the corresponding items in General Formula (1) or General Formula (2), respectively.)
