摘要:
The invention provides a diphenol represented by the general formula (I) wherein X is a divalent cyclic hydrocarbon group selected from 1-cyclohexene-1,4-ylene group, 1,4-cyclohexylene group and p-phenylene group, R is an alkyl group of 1-4 carbon atoms, n is 0 or an integer of 1-3 when X is 1-cyclohexene-1,4-ylene group and an integer of 1-3 when X is 1,4-cyclohexylene group or p-phenylene group. The invention further provides a process for the production of the same.

摘要:
Poly(ortho-methylphenol) is obtainable at high purities and yields using industrial processes by causing a secondary amine and formaldehyde to react with a polyphenol (first step), and then breaking down the aminomethyl group of the obtained poly(ortho-aminomethyl)phenol by means of hydrogenolysis in the presence of a hydrogenation catalyst (second step).
