We describe a three-step bromine-mediated process for oxidative coupling of methane using O 2 as oxidant. In the first step, a supported metal bromide solid is treated with O 2 to generate Br 2 and supported metal oxide. The Br 2 thus formed reacts with excess CH 4 , giving a mixture of CH 4 , bromomethanes, and HBr. This mixture is passed over a CaO/zeolite...
We describe a novel, integrated multi-step process for the partial oxidation of alkanes to alcohols, ethers or olefins using O 2 as oxidant. The sequential transformations are (1) alkane bromination to alkyl bromide(s) and HBr, (2) reaction of this mixture with solid metal oxide (MO) to neutralize the HBr and to generate oxygenated products or olefins plus solid metal bromide, and (3) oxidation...
In recent years, the important role of the organic matrix for the mechanical properties of bone has become increasingly apparent. It is therefore of great interest to understand the interactions between the organic and inorganic constituents of bone and learn the mechanisms by which the organic matrix contributes to the remarkable properties of this complex biomaterial. In this paper, we present a...
