| titleOfInvention | Novolak resin manufacturing method |
| abstract | (57) [Problem] To provide a method for industrially advantageously producing a phenolic novolak resin having an ortho ratio of 30% or more with a high yield. A method for producing a phenol novolak resin having an ortho ratio of 30% or more is characterized in that a crude phenol novolak resin having an ortho ratio of less than 30% is heated at 110 to 180 ° C under a strong acidic catalyst. . |
