Application of the Emend Process (Tebbe Reaction followed by hydrogenation)... 

A considerable effort has been emended in the past few years by many researchers in attempts to better understand the mechanism by which coal is liquefied. From this work has emerged the concept of short residence time coal liquefaction which promises potential process advantages, small reactor, minimum hydrogen flow, and the efficient utilization of hydrogen for a particular product slate. 

In order to process the emended data in as unprejudiced a manner as possible, we adopted as our fundamental variable for correlating structure with affinity the intramolecular distance of an alkyl fragment of a bound ligand from its ammonium ion. The rationale for this approach is that the binding site for the... 

Eq. (4) gives k (co) for a relaxation process, with a relaxation time and with zero-frequency and high-frequency limits for k (w) of Kg and k, respectively. Two complicating features render the Debye equation, Eq. (4), approximate, and require emendation (a) a given relaxation process may be associated with a...
