Method for producing phenol resin, phenol resin, epoxy resin and epoxy resin composition |
| abstract |
The present invention provides a process for producing benzo with good yield and easy and safe process A method for producing a phenol resin of a structural epoxy resin, a phenol resin, an epoxy resin, and an epoxy resin composition containing the same. The phenol resin represented by the following formula (1) is produced by reacting dihydroxynaphthalene with a ketone under an organic acid catalyst.n n n n n n n n n n (wherein R 1 and R 2 represent a hydrogen atom or the like, and k represents an integer of 1 to 4). |
