Abstract
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.
Claims7
A method for producing a polynuclear poly(formylphenol) expressed by General Formula (2), characterized in that a polynuclear polyphenol expressed by General Formula (1) is caused to react with hexamethylene tetramine in the presence of an acid, and then the obtained reaction product is hydrolyzed:
- wherein all Rs may be the same or different and respectively represent a hydrogen atom or aromatic hydrocarbon group, hydroxyl group, or aliphatic hydrocarbon group that may have an ether group;
- R1, R2 and R3 may be the same or different and respectively represent a hydrocarbon group, hydrocarbon group containing oxygen atom, hydroxyl group, halogen group or halogenated hydrocarbon group;
- a and c respectively indicate an integer of 0 or 1 to 3, while b indicates an integer of 0, 1 or 2;
- l and n respectively indicate an integer of 1 to 3;
- m indicates an integer of 0, 1 or 2;
- X indicates a bond group or single bond;
- and Y indicates a bivalent alkylene group;
- wherein R1, R2, R3, a, b, c, l, m, n, X and Y indicate the same things represented by the corresponding symbols in General Formula (1), wherein the CH2OR's in General Formula (1) are converted into the CHO's in General Formula (2).
