Abstract

PURPOSE: To prepare the titled compound useful as a rubber stabilizer, etc., economically, by reacting a polyalkylbenzene with a 2,6-dialkylphenol and formaldehyde or its oligomer in the presence of an acidic catalyst.
CONSTITUTION: A polynuclear polyphenol of formula III (R1 is lower alkyl; R2 and R3 are 1W8C alkyl; n is 3 or 4) useful as a stabilizer of rubber, gasoline, lubricating oil, polyolefin, etc., or a color developing agent of heat-sensitive copying paper, is prepared from a polyalkylbenzene of formula I, in one step, economically in high yield, by reacting (A) a compound of formula I, esp. 1,3,5-trimethylbenzene, (B) a 2,6-dialkylphenol of formula II, esp. 2,6-di-tert-butylphenol, and (C) formaldehyde or its oligomer, in the presence of an acidic catalyst, esp. sulfuric acid and peferably a lower aliphatic monohydric alcohol.
