Quaranta E. Chemical upcycling of poly(bisphenol A carbonate) via sequential diamino-/methanolysis: A phosgeneless one-pot route to dimethyl dicarbamate esters. JOURNAL OF HAZARDOUS MATERIALS 2025; 484:136700. [PMID: 39637778 DOI: 10.1016/j.jhazmat.2024.136700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2024] [Revised: 11/14/2024] [Accepted: 11/26/2024] [Indexed: 12/07/2024]
Abstract
Waste poly(bisphenol A carbonate) (PC) is a potential source of harmful bisphenol A (BPA). In this study a new approach aiming to chemically valorize hazardous PC wastes is described. A one-pot process has been developed that allows to recover BPA from PC used as "phosgene equivalent" for the synthesis of dimethyl dicarbamates MeO2CNH-R-NHCO2Me. Dicarbamate esters are industrially relevant precursors of non-isocyanate polyurethanes and polyureas. The devised process is conducted stepwisely. PC is first depolymerized by reaction with basic diamines H2NRNH2 (1,6-diaminohexane (3a); 4,7,10-trioxa-1,13-tridecanediamine (4a); meta-xylylenediamine (5a); para-xylylenediamine (6a)) into BPA and oligourethanes H[-OArO(O)CNHRNHC(O)-]nOArOH (Ar = 4,4'-C6H4C(Me)2C6H4-) that, in a subsequent step, are one-pot converted into MeO2CNH-R-NHCO2Me and more BPA by transurethanization with methanol. Both the steps proceed under mild conditions and do not require any auxiliary catalyst. The process allows to recover BPA in high yield and, as an additional outstanding advantage, offers a new solution to the synthesis of MeO2CNH-R-NHCO2Me dicarbamates without using poisonous phosgene, traditionally used to this purpose. Aromatic diamines are much less reactive than aliphatic ones. Under conditions comparable with those used for 3a-6a, 4,4'-diaminodiphenylmethane reacted with PC under the assistance of a base catalyst (DBU; NaOH) to give polyurea [-NHRNHCO-]n as major product.

Abstract
The production and degradation of polyesters are two crucial processes in polyester materials' life cycle. In this work, multi-functional organocatalysts based on fluorides for both processes are described. Organofluorides were developed as catalysts for ring-opening polymerization of lactide (lactone). Compared with a series of organohalides, organofluoride performed the best catalytic reactivity because of the hydrogen bond interaction between F- and alcohol initiator. The Mn values of polyester products could be up to 72 kg mol-1 . With organofluoride catalysts, the ring-opening copolymerization between various anhydrides and epoxides could be established. Furthermore, terpolymerization of anhydride, epoxide, and lactide could be constructed by the self-switchable organofluoride catalyst to yield a block polymer with a strictly controlled polymerization sequence. Organofluorides were also efficient catalysts for upcycling polyester plastic wastes via alcoholysis. Mixed polyester materials could also be hierarchically recycled.

Abstract
Polymers (plastics) have transformed our lives by providing access to inexpensive and versatile materials with a variety of useful properties. While polymers have improved our lives in many ways, their longevity has created some unintended consequences. The extreme stability and durability of most commercial polymers, combined with the lack of equivalent degradable alternatives and ineffective collection and recycling policies, have led to an accumulation of polymers in landfills and oceans. This problem is reaching a critical threat to the environment, creating a demand for immediate action. Chemical recycling and upcycling involve the conversion of polymer materials into their original monomers, fuels or chemical precursors for value-added products. These approaches are the most promising for value-recovery of post-consumer polymer products; however, they are often cost-prohibitive in comparison to current recycling and disposal methods. Catalysts can be used to accelerate and improve product selectivity for chemical recycling and upcycling of polymers. This review aims to not only highlight and describe the tremendous efforts towards the development of improved catalysts for well-known chemical recycling processes, but also identify new promising methods for catalytic recycling or upcycling of the most abundant commercial polymers.

JOURNAL OF HAZARDOUS MATERIALS 2021; 403:123957.

Abstract
The present study describes an unprecedented approach to valorize potentially hazardous poly-(bisphenol A carbonate) (PC) wastes. In THF, under non-severe conditions (120 °C), the reaction of PC with long-chain diamines H2NRNH2 (2 equivalents) provided a tool to regenerate the monomer bisphenol A (BPA; 83-95%, isolated) and repurpose waste PC into [-NHRNHCO-]n polyureas (PUs; 78-99%, isolated) through a non-isocyanate route. Basic diamines (1,6-diaminohexane, 4,7,10-trioxa-1,13-tridecanediamine, meta-xylylenediamine, para-xylylenediamine) reacted with PC without any auxiliary catalyst; less reactive aromatic diamines (4,4'-diaminodiphenylmethane, 2,4-diaminotoluene) required the assistance of a base catalyst (1,8-diazabicyclo[5.4.0]undec-7-ene, NaOH). The formation of [-NHRNHCO-]n goes through a carbamation step affording BPA and carbamate intermediates H[-OArOC(O)NHRNHC(O)-]nOArOH (Ar=4,4'-C6H4C(Me)2C6H4-) that, in a subsequent step, convert into [-NHRNHCO-]n and more BPA. All the PUs were characterized in the solid state by CP/MAS 13C NMR (δ(CO) = 152-161 ppm) and IR spectroscopy. The positions of ν(N-H) and ν(CO) absorptions are typical of "hydrogen-bonded ordered" bands suggesting the presence of H-bonded groups in network structures characterized by some degree of order or regularity. DSC and TGA analyses showed that the PUs are thermally stable (Td,5%: 212-270 °C) and suitable for being processed since their degradation begins at temperatures about 100 °C higher than their Tg or Tm.

Abstract
The present study describes the first example of utilization of a natural clay mineral as catalyst in a process addressed to chemical valorization of poly-[bisphenol A carbonate] (PC; (1)) wastes. A natural clinochlore was investigated for the first time as the catalyst of the hydrolysis reaction of 1, a potential route to chemical recycling of wastes of this polymeric material. At 473 K, in tetrahydrofuran (THF) as the solvent, the mineral promoted effectively the depolymerization (up to 99%, after 6 h) of 1 by H2O and the selective (~99%) regeneration of the monomer bisphenol A (BPA, (2)). Temperature, catalyst loading, reaction time, H2O/PC weight ratio affected markedly the productivity of the process. The role of the catalyst was also focused: the experimental data showed that the exposed brucite-like sheets of clinochlore are involved in the hydrolysis reaction and take active part in promoting the depolymerization process.

Abstract
The valorization of waste to valuable chemicals can contribute to a more resource-efficient and circular chemistry. In this regard, the selective degradation of end-of-life polymers/plastics to produce useful chemical building blocks can be a promising target. We have investigated the hydrogenative depolymerization of end-of-life poly(bisphenol A carbonate). Applying catalytic amounts of the commercial available Ruthenium-MACHO-BH complex the end-of-life polycarbonate was converted to bisphenol A and methanol. Importantly, bisphenol A can be reprocessed for the manufacture of new poly-(bisphenol A carbonate) and methanol can be utilized as energy storage material.
