摘要: A method of manufacture of novolac-type phenol resin, wherein phenols and aldehydes are allowed to react with each other, a water-soluble organic phosphonic acid is used as a reaction catalyst, and a tertiary phosphine compound is used as a reaction promoter. It is preferable that the aforementioned organic phosphonic acid have the structure shown in the following general formula (1): R—PO(OH)2 (1) (R is a group which contains a carbon atom, and which contains —COON and/or —PO(OH)2).

摘要: A novolak-type phenol resin with less unreacted phenol and a narrow molecular weight distribution is produced in high yield by reaction of a phenol with an aldehyde using an organophosphonic acid as a catalyst, while keeping a water concentration of reaction system at not more than 30% by weight and a reaction temperature at 110° C.-200° C.
