A lanthanide metal-organic framework (MOF) Yb(BTC)(H2O)·(DMF) (BTC = 1,3,5-benzenetricarboxylate, DMF = N,N-dimethylformamide) was prepared from Yb(NO3)3·5H2O and H3BTC using the solvothermal method and characterized by Fourier transform IR spectroscopy, X-ray diffraction, thermogravimetric anal., SEM, N2 adsorption-desorption technol., and temperature-programmed desorption. The results show that Yb(BTC)(H2O)·(DMF) is a lanthanide MOF with an excellent thermal stability. The coordinated water mols. and DMF guest mols. were removed from the channels by calcination to form a porous solid Yb (BTC) with coordinatively unsaturated Yb3+ sites. The BET surface area and pore size of Yb(BTC) are 695 m2/g and 0.68 nm, resp. As a heterogeneous Lewis acid catalyst, the activity of Yb(BTC) for the synthesis of polycarbonate diol (PCDL) via transesterification between di-Ph carbonate and diol was investigated. Compared with nine reported catalysts, Yb(BTC) exhibits the highest catalytic activity for the synthesis of PCDL. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Product Details of 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Product Details of 102-09-0
