Example 1 The phenol resin (I) 194.4 synthesized in Reference Example 1
Parts, epichlorohydrin 462.5 parts, and diethylene glycol dimethyl ether 92.5 parts were placed in a glass separable flask and heated to 60 ° C. with stirring to dissolve. Next, under a reduced pressure of 110 mmHg, the temperature is adjusted to 58-
While maintaining the temperature at 62 ° C., 80 parts of a 49 wt% sodium hydroxide aqueous solution was added dropwise over 4 hours. During this period, epichlorohydrin and water that azeotropically distilled off were statically separated, water was sequentially removed from the system, and epichlorohydrin was sequentially returned to the system. After the reaction was completed, epichlorohydrin was recovered under reduced pressure at 180 ° C., and methyl isobutyl ketone 560 was collected.
2 parts, and allowed to react for 2 hours at a temperature of 80 to 90 ° C.
30 parts of water was added to dissolve the by-produced sodium chloride, and the liquid was separated and removed. After neutralization with a phosphoric acid aqueous solution, washing with water was repeated several times and filtration was performed. Methyl isobutyl ketone was evaporated and removed under reduced pressure at 180 ° C. to obtain 243 parts of an objective co-condensation type phenol resin epoxy resin. The resin was a reddish brown, brittle solid. Table 2 shows the softening point, epoxy equivalent, melt viscosity, and hydrolyzable chlorine of this resin. The resin obtained in this example was designated as epoxy resin (I).
