Diphenolic acid is emerging as a promising "green" alternative to bisphenol A for the production of epoxy resins and polycarbonate plastics. The DPA synthesis involves a condensation reaction between phenol and levulinic acid, catalyzed by Brønsted acid catalysts, in particular mineral ones, which lead to significant corrosion issues and difficult catalyst recycling. Therefore, it is paramount to move towards heterogeneous systems, especially those derived from renewable resources. In this specific domain, the PRIN 2020 LEVANTE project focuses on synthesizing a fully renewable p,p’-DPA. At the same time, LCA (Life Cycle Assessment) evaluation is in progress to compare environmental impacts associated to the newly developed preparation of DPA with those of the consolidated process which involves mineral acids as catalysts.

Abstract
Diphenolic acid is emerging as a promising "green" alternative to bisphenol A for the production of epoxy resins and polycarbonate plastics. The DPA synthesis involves a condensation reaction between phenol and levulinic acid, catalyzed by Brønsted acid catalysts, in particular mineral ones, which lead to significant corrosion issues and difficult catalyst recycling. Therefore, it is paramount to move towards heterogeneous systems, especially those derived from renewable resources. In this specific domain, the PRIN 2020 LEVANTE project focuses on synthesizing a fully renewable p,p’-DPA. At the same time, LCA (Life Cycle Assessment) evaluation is in progress to compare environmental impacts associated to the newly developed preparation of DPA with those of the consolidated process which involves mineral acids as catalysts.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
