Abstract
NEW MATERIAL:1,1,3-Trimethyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)-6-t-butylinedane-5-ol of formula I (R is t-butyl).
USE: A stabilizer for vinyl chloride resins, polyethylene, polypropylene, polyurethane, polystyrene and rubbers.
PREPARATION: p-Isopropenylphenol or its oligomers are converted to the linear dimers of formula II and III by conventional method and the resulting dimers are cyclized in the presence of an acid catalyst e.g., Lewis acid such as aluminum trichloride, protonic acid such as sulfuric acid or solid acid such as silica-alumina to prepare 1,1,3-trimethyl-3-(4-hydroxy-phenyl) indane-5-o1. Then a butylation reagent is made to act on the product to produce the objective compound of formula I.
