Abstract

Process for obtaining 2,4-bis- (hydroxyphenyl) -butanes, of formula I ** (See formula) ** where R is H, CN, CH3 or Cl; R1 and R2, which are the same or different, signify H, Cl, CH3, (CH3) 2CH-, OH or -O-CH3; characterized in that phenols of formula II: ** (See formula) ** in which R1 and R2 have the meanings indicated above and which have at least one free o o p position with respect to the OH group, are reacted with butadiene of formula III: ** (See formula) ** in which R has the meaning indicated above, in the presence of an anhydrous acid, at temperatures between 40ºC and 250ºC.
