Zusammenfassung:Ru-MACHO®-BH is an effective catalyst for controlled depolymerization of polybutylene succinate. Under low pressure hydrogen the catalyst produces gamma -butyrolactone via a novel transfer hydrogenation wherein dehydrogenation and hydrogenation deconstruct the polymer chain. Simply increasing the hydrogen pressure selectively generates 1,4-butanediol. Ru-MACHO®-BH catalyzes a novel transfer hydrogenation depolymerization of polybutylene succinate to gamma -butyrolactone at low pressures. High pressure hydrogen converts the system to a hydrogenative depolymerization.
