MIXTURE OF 2,4-DIMETHYL-6-SEC-ALKYLPHENOLS SHOWING STABILIZING ACTION Russian patent published in 1996 - IPC

FIELD: organic chemistry. SUBSTANCE: product: mixture of 2,4-dimethyl-6-sec. -alkylphenols of the formula (I) and (II) where R₁ means C_mH_m+1 and R₂-C_m-1H_2m-1,; m - the whole number from 8 to 30 and has similar value for R₁ and R₂. Product is synthesized by 2,4-dimethylphenol alkylation with the corresponding alpha-olefin-C₈-C₃₀ at 80-250 C in the presence of acid catalyst, for example, p-toluenesulfoacid, zeolite, sulfocationite and others. Synthesized mixture of trialkylphenols is used for organic polymeric materials stabilization. ?? ?EFFECT: improved method of synthesis. 4 cl, 4 tbl
