摘要:
Produce the target substance, or a polynuclear poly(formylphenol) expressed by General Formula (2), in an industrial setting with ease and at high purity by causing a polynuclear poly(hydroxymethylphenol) or polynuclear poly(alkoxymethylphenol) to react with hexamethylene tetramine in the presence of an acid and then hydrolyzing the obtained reaction product.
摘要:
Disclosed are tetrakis(ether-substituted formylphenyl) expressed by General Formula (1), as well as polynuclear polyphenol derived from such tetrakis(ether-substituted formylphenyl): (In the formula, R1 represents an alkyl group with 1 to 8 carbon atoms or alkoxyl group with 1 to 8 carbon atoms, or aromatic hydrocarbon group or saturated hydrocarbon group with 1 to 8 carbon atoms having an aromatic hydrocarbon group, n represents 0 or an integer of 1 to 3, R2 represents a divalent monocyclic or fused-ring aromatic hydrocarbon group with 6 to 15 carbon atoms or divalent aliphatic hydrocarbon group with 1 to 8 carbon atoms that may have a monocyclic or fused-ring aromatic hydrocarbon group with 6 to 15 carbon atoms, R3 represents a hydrogen atom or alkyl group with 1 to 6 carbon atoms, A represents a tetravalent carbon atom group or tetravalent saturated hydrocarbon group with 2 or more carbon atoms, where, if A is a tetravalent saturated hydrocarbon group with 2 or more carbon atoms, the two carbon atoms in the A group are bonded with two phenyl groups, respectively.)

摘要:
Provided is a polynuclear poly(phenol)family represented by general formula (1). In general formula (1), R1s are each independently C1-8 alkyl group, C1-8 alkoxy group, an aromatic hydrocarbon group, or a C1-8 saturated hydrocarbon group having an aromatic hydrocarbon group; n is 0 or an integer of 1 to 3; X is a hydroxyphenyl group represented by general formula (2); and A is a tetravalent carbon atom group or a tetravalent saturated hydrocarbon group having two or more carbon atoms, with the proviso that when A is a tetravalent saturated hydrocarbon group having two or more carbon atoms, two carbon atoms in the A group are each bonded to two phenyl groups.
摘要:
A bis(formylphenyl) compound expressed by general formula (1) is manufactured by, for example, using a corresponding bis(hydroxy-formylphenyl) compound as the direct material and causing it to react with a halogenated alkoxycarbonyl hydrocarbon in the presence of a base according to a known phenylether manufacturing method.
摘要:
A polynuclear polyphenol compound is constituted by, as a main skeleton, a 4,4′-methylene bis phenol structure where tris phenol skeletons of tris phenyl methane type are mutually bonded by methylene groups, wherein the reactivity of two hydroxyl groups bonded to the central skeleton of 4,4′-methylene bis phenol is significantly different from the reactivity of hydroxyl groups respectively bonded to the four phenyl groups of the two diphenyl methyl substituted groups.
