Case 6080 STABILIZER COMPOSITIONS Abstract of the Disclosure Liquid mixtures of alkyl phenols composed of from 1 to 8 wt% of 2-tert-butylphenol; from 4 to 12 wt% of 2,6-di-tert-butyl- phenol; from 4 to 12 wt% of 2-tert-butyl-4-n-butylphenol; from 4 to 12 wt% of 2,4,6-tri-tert-butylphenol; and from 65 to 80 wt% of 2,6-di-tert-butyl-4-n-butylphenol having a balance of properties rendering them ideally suited for use as stabilizers for middle distillate fuels. Such mixtures can be readily produced by an aldehyde-catalyzed alkylation procedure using n-butanol, an appropriate mixture of tertiary butylated phenols, and a strong ;base (e.g., NaOH, KOH, etc.).
