Abstract

Para-octylphenol and para-tert-butylphenol are prepd. by passing a warm mixt. of phenol and diisobutylene through a fixed bed catalyst of solid cation exchange resin in the acid form carrying sulphonic gps. in the anhydrous or 10-20 wt.% hydrated form; distilling the reaction prod. without pretreatment to separate and recycle the unreacted starting materials and to selectively obt. one of the prods. Para-octylphenol is obtd. with a reaction temp. of 85-110 degrees C whilst para-tert-butylphenol is obtd. at 120-130 degrees C. When a hydrated catalyst is employed the mixt. of reactants may be hydrated to the amt. of 1-2 wt.% (based on the wt. of phenol). The cation exchange resin is pref. macroporous and in the form of 0.2-0.5 mm dia. balls. It may be sulphonated polystyrene cross-linked with divinylbenzene. A catalyst hydrated with 10-15 wt.% water is pref. used in para-octylphenol prepn. at 100-105 degrees C and an anhydrous catalyst at 125-130 degrees C is pref. used to prepare para-tert-butylphenol. The alkylphenols obtd. are starting materials for the prodn. of phenoplasts. The process is non-polluting, uses a cheap catalyst and recycling of starting materials improves yields.
