    摘要: 4-(m,m'-ditert.-butyl-p-hydroxyphenyl)-butan-2-ones are produced by reaction of a 4-hydroxybutanone-(2) with 2,6-ditert.-butylphenol in the presence of a strong acid at elevated temperature. The compounds obtainable by the process, particularly 4-(m,m'-ditert.-butyl-p-hydroxyphenyl)-butane-2-one, are starting materials for the production of dyes, pest control agents and plastics auxiliaries and particularly of stabilizers for polyolefins and polyamides.
