Chem. recycling of plastic waste represents a greener alternative to landfill and incineration, and potentially offers a solution to the environmental consequences of increased plastic waste. Most plastics that are widely used today are designed for durability, hence currently available depolymerization methods typically require harsh conditions and when applied to blended and mixed plastic feeds generate a mixture of products. Herein, we demonstrate that the energetic differences for the glycolysis of BPA-PC and PET in the presence of a protic ionic salt TBD:MSA catalyst enables the selective and sequential depolymerization of these two commonly employed polymers. Employing the same procedure, functionalized cyclic carbonates can be obtained from both mixed plastic wastes and industrial polymer blend. This methodol. demonstrates that the concept of catalytic depolymerization offers great potential for selective polymer recycling and also presents plastic waste as a “greener” alternative feedstock for the synthesis of high added value mols. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Related Products of 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Related Products of 102-09-0
