실험 절차

In the present invention, the solution comprising BPTMC and phenol can be any solution containing BPTMC and phenol and is not particularly limited, but preferably an oil phase containing BPTMC and phenol, which is obtained by reacting phenol and 3,3,5-trimethylcyclohexane in the presence of an acid catalyst, neutralizing the resulting reaction mixture after completion of the reaction and then removing a water phase; this water phase is cooled to crystallize the BPTMC-phenol adduct and the crystallized BPTMC-phenol adduct (phenol adduct crystal) is isolated, for example, by filtration to obtain the BPTMC-phenol adduct. In this case, the resulting phenol adduct crystal generally contains isomers, high boiling point byproducts such as polymers, colored byproducts and trace impurities such as sodium, besides BPTMC and phenol. Therefore, colorless high purity BPTMC could not generally be obtained without such operations as dissolution, recrystallization and filtration of this BPTMC-phenol adduct using a solvent.
