| titleOfInvention | Manufacturing method for phenolic novolac resin and resin-coated sand |
| abstract | A process for producing a phenol novolac resin obtained by reacting a phenol and formaldehyde in the presence of a metal compound as a catalyst for the reaction and further adding a chelating agent to the catalyst in order to inactivate the catalytic action of the metal compound, A process for producing a resin, and a resin-coded sand using the phenolic novolac resin. A method of producing a phenol novolak resin having an excellent yield (70% or more) and an ortho ratio of 30 to 60%, preferably an ortho ratio of 40 to 55%, and a method using a phenol novolak resin, You can provide a sand. |
