Zur Bisphenolherstellung werden im allgemeinen 2 bis 10 Mol, vorzugsweise 2,5 bis 6 Mol Phenol (V) pro Mol Keton (VI), verwendet. Bevorzugte Reaktionszeiten betragen 1 bis 100 Stunden. Im allgemeinen arbeitet man bei Temperaturen von -30°C bis 300°C, vorzugsweise von -15°C bis 150°C, und bei Drücken von 1 bis 20 bar, vorzugsweise von 1 bis 10 bar.For bisphenol production, generally 2 to 10 mol, preferably 2.5 to 6 moles of phenol (V) per mole of ketone (VI) used.

In manchen Fällen verläuft die Reaktion nicht ganz einheitlich, d. h. es können mehrere, unterschiedliche Produkte entstehen, so daß die gewünschte Verbindung zunächst aus einem Gemisch isoliert werden muß. Für Einzelheiten der Kondensation sei auf Schnell, Chemistry and Physics of Polycarbonates, Interscience Publishers, New York 1964, verwiesen. Manchman kann die Reaktion durch Wahl entsprechender Katalysatoren und Reaktionsbedingungen so gesteuert werden, daß die gewünschte Verbindung ausfällt oder auskristallisiert, was deren Isolierung erleichtert. In some cases, the reaction is not entirely uniform, d. H. there can be several different products arise so that the desired connection first must be isolated from a mixture. For details condensation on Schnell, Chemistry and Physics of Polycarbonates, Interscience Publishers, New York 1964. Sometimes the reaction by choosing appropriate catalysts and Reaction conditions are controlled so that the desired compound fails or crystallizes out, which facilitates their isolation.
