| titleOfInvention | Method for producing novolak type epoxy resin |
| abstract | An object of the present invention is to provide a method for producing a novolak-type epoxy resin having a reduced content of a phenol monomer and a phenol dimer in a high yield. A first step of heterogeneously reacting phenols and aldehydes in the presence of phosphoric acids, and a second step of reacting the novolak-type phenol resin obtained in the first step with epihalohydrin A method for producing a novolak epoxy resin. [Selection diagram] None |
