ABSTRACT:
A process for the production of mixtures of alkylated aromatic polyhydroxy compounds by reacting alkylated phenols with carbonyl compounds, wherein acidic organic ion exchangers are used as catalysts and commercial dialkyl phenols as the phenol and any unreacted starting phenols separated off are completely recycled into the process without intermediate purification, and the application of the thus produced polyhydroxyl compounds for making thermoplastic polycarbonates.
