PREPARATION PROCESS OF 4,4'-BIPHENOL, PRECURSOR OF SAME AND PREPARATION PROCESS OF PRECURSOR

摘要

A novel compound, 4-(4-hydroxyphenyl)-3-cyclohexene-1-ol, and a novel preparation process of 4,4'-biphenol by using the novel compound as the raw material. 4-(4-Hydroxyphenyl)-3-cyclohexene-1-ol can be obtained by conducting a thermal decomposition reaction of 4,4-bis(4-hydroxyphenyl)cyclohexanol. 4,4'-Biphenol can be industrially manufactured by conducting a dehydrogenation reaction of 4-(4-hydroxyphenyl)-3-cyclohexene-1-ol.
