Application

  • Depolymerization of poly (bisphenol A carbonate) under mild conditions by solvent-free alcoholysis catalyzed by 1, 8-diazabicyclo undec-7-ene as a recyclable: DBU catalyzes the depolymerization of polycarbonates under mild, solvent-free conditions, demonstrating its effectiveness and recyclability as a catalyst (E Quaranta, D Sgherza, G Tartaro, 2017).
  • Activating cellulose via its reversible reaction with CO2 in the presence of 1, 8-diazabicyclo undec-7-ene for the efficient synthesis of cellulose acetate: This research shows how DBU can activate cellulose for a reversible reaction with CO2, facilitating the synthesis of cellulose acetate (Y Yang, L Song, C Peng, E Liu, H Xie, 2015).
  • Bifunctional 1, 8-Diazabicyclo undec-7-ene for Visible Light-Induced Heck-Type Perfluoroalkylation of Alkenes: DBU acts as a bifunctional organocatalyst for visible light-induced Heck-type perfluoroalkylation of alkenes, showcasing its potential in photoredox catalysis (L Tang, G Lv, Y Fu, XP Chang, R Cheng, 2022).
  • Cooperative calcium-based catalysis with 1, 8-diazabicyclo undec-7-ene for the cycloaddition of epoxides with CO2 at atmospheric pressure: This study demonstrates the cooperative catalysis of CaBr2 and DBU in the cycloaddition of epoxides with CO2, highlighting a sustainable approach to carbonate synthesis (X Liu, S Zhang, QW Song, XF Liu, R Ma, LN He, 2016).

Questions

  1. After opening, is it necessary to preserve it with argon or other noble gases, or can it be stored directly in a 4°C refrigerator? How long will its performance remain unchanged after opening?

    1 answer

    1. Purging with inert gas is not necessary for this product. The recommended storage 2-30°C. The lot-specific Certificate of Analysis provides shelf life information, as product quality integrity is reflected by those dates.
