A synthesis of copper based metal-organic framework for O-acetylation of alcohols
摘要:
A novel metal-organic framework, Cu-BDC was synthesized by static hydrothermal method using innocuous solvents and characterized by several techniques such as powder XRD, ESR, TG-DTA, elemental analysis, ICP-AES, SEM, EDXS, FT-IR, BET surface area, pore volume and pore size. The catalytic performance of Cu-BDC was explored for O-acetylation of alcohols under solvent-free conditions at room temperature. The catalyst exhibited remarkable activity and reusability affording the desired products in excellent yields. (C) 2013 Elsevier B.V. All rights reserved.

The Cu- and Ti-containing composition of the present invention contains titanium oxide including rutile-crystal-type titanium oxide, and a divalent copper compound, wherein the rutile-crystal-type titanium oxide exhibits the most intense diffraction peak attributed to rutile-type titanium oxide having a full width at half maximum of 0.65° or less, in a Cu—Kα line X-ray diffraction pattern, which is obtained by plotting intensity of diffraction line with respect to diffraction angle 2θ. The composition exhibits excellent anti-viral property under light and in the dark, and excellent organic compound degradability under light.

for benzene hydroxylation was evaluated. The results showed that the Fe@Cu‐BDC catalysts had favorable catalytic activity for benzene hydroxylation. The yield of products can reach ca 37% and the selectivity of phenol can reach ca 62% over the 6% Fe@Cu‐BDC catalyst at 60°C in a reaction time of 75 min. Furthermore, the contents of Fe and solvent played a key role in benzene hydroxylation. After the
