The thermo-oxidative stability and antioxidant effectiveness of bisphe
nols obtained by the condensation of 2-tert-butyl-4-methylphenol with
C-1-C-5 aldehydes of aliphatic series have been studied for the first
time. It has been established that these features of synthesized bisph
enols depend on the structure of the hydrocarbon ''bridge'' between th
e phenyl groups, and their oxidation proceeds according to the laws go
verning the process of Liquid-phase oxidation. It has been shown that
the degradation of the investigated series of bisphenols is described
by a kinetic equation with an order of the reaction of 1.25n and E-n =
74.4 kJ/mole. (C) 1997 Elsevier Science Ltd. All rights reserved.
