Methods of synthesizing and purifying ethers are described. The synthesis and purification are achieved using an etherification technique followed by one or two fractional distillations. The etherification utilizes an element having low work function properties. Examples of low work function elements include, but are not limited to, metals or their hydrides, such as sodium, lithium or potassium or some combination thereof. This technique yields ethers of greater than 90% purity.

Method for the synthesis and purification of ethers

Pyrolysis of machined osseous tissue results in a monolith of carbon interwoven within the HA scaffold native to the original tissue. This HA framework prevents the collapse of the carbon to dense forms during pyrolysis. Upon removal of the HA scaffold after pyrolysis, a monolith that preserves the macroscopic form of the carbon remains. The monolith is placed in a solution of catalyst, noble metal ions for example, which is then reduced to facilitate the precipitation of nanoparticles of the catalyst. The novelty of this invention is that a high number of particles are contained within a relatively small, extremely high surface area solid support. The current invention demonstrates that the pyrolysis of intact bovine cortical bone produces high-carbon-surface-area monoliths, which can be used as a scaffold for reusable catalysts.
