Formaldehyde → Bis(2-hydroxyphenyl)methane

Participants

Reaction Steps

Stoichiometrically excess phenol and formaldehyde are introduced into a preparation step 1 (from a reaction step to a phenol-removal step). More specifically, to a reactor equipped with, for instance, a stirring machine, a temperature control device, a reflux condenser, a complete condenser and a vacuum device, there are charged phenol, formaldehyde and an acid catalyst and these ingredients are reacted at a determined temperature for a desired period with stirring. Then the acid catalyst, the water formed during the reaction and the unreacted phenol are removed from the reaction product to give crude bisphenol F 2.
