FIELD: organic chemistry. SUBSTANCE: product: mixture of 2,4-dimethyl-6-sec. -alkylphenols of the formula (I)
and (II)
where R1 means CmHm+1 and R2-Cm-1H2m-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
