Abstract: A novel chemical looping technology for the synthesis of 2,2′-dibenzothiazole disulfide (MBTS) with zero emissions has been developed. Through chemical cycling between carbonate and bicarbonate in the reaction system, the insoluble 2-mercaptobenzothiazole (MBT) can become soluble in the aqueous phase of sodium carbonate and then be oxidized efficiently by hydrogen peroxide and the ab...

Abstract: Ring-opening polymerization (ROP) of lactones catalyzed by 1,5,7-triazabicyclo[4,4,0]decane-5-ene (TBD) is a highly efficient method for synthesizing aliphatic polyester materials. In order to create a green and sustainable synthetic route for poly(δ-valerolactone) with a narrow molecular weight distribution, we propose CO2 as the terminator instead of conventional organic acids, whi...

Abstract: Monodispersed polysilsesquioxane (PSQ) spheres with diameters from hundreds of nanometers to several microns have been successfully synthesized; however, the knowledge of their formation mechanism still lags behind. Herein, with methyltrimethoxysilane and 3-mercaptopropyl trimethoxysilane as model silicon sources, the formation process of PSQ spheres in the one-step sol–gel method wa...

Abstract: The kinetics of aliphatic polyester synthesis is critical to understanding the mechanism of ring-opening polymerization and making the reaction more controllable. In this paper, we introduce a gas-driven droplet flow reactor to determine the reaction kinetics of 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) catalyzed δ-valerolactone polymerization. Only 2 mL reaction solution was used fo...

Abstract: We herein propose a highly efficient method for the synthesis of polyvinyl butyral (PVB), an important resin material used for laminated glass in vehicles. The condensation reaction between polyvinyl alcohol (PVA) andn-butanal was successfully implemented in a reaction system containing a membrane dispersion microreactor and an aging vessel reactor, allowing the energy costs associate...
