The cuprous chloride then reoxidizes rapidly with oxygen reforming cupric ion. Thus, the oxidation can be carried out completely catalytically in palladium and copper. 

Next, the leaving group, ethoxide ion, departs as an electron pair from the negative oxygen reforms the double bond of the carbonyl group. 

The electrons on the negative oxygen reform the pi bond as ethoxide ion leaves. 

The reactions in this chapter follow the same general mechanism. First, the nucleophile bonds to the carbonyl carbon, displacing the pi electrons of the CO double bond onto the oxygen and forming the tetrahedral intermediate. In the second step the unshared electrons on the oxygen reform the pi bond as the leaving group leaves ...

In path A, the electrons on the negative oxygen reform the double bond as hydride leaves. Hydride is too basic to leave by itself, so it is transferred to the electrophilic carbonyl carbon of another aldehyde molecule in a concerted step. This step is relatively slow and occurs only when no other reaction pathways, such as an aldol condensation, are available. 

The configuration of a 7000 MTPD DME plant is based on the combination of methanol synthesis and methanol dehydration. Attractive features of this process include lesser total investment cost and lesser oxygen consumption when compared with the methanol/DME coproduction route or direct DME synthesis route. Also, carbon dioxide is not produced in the DME synthesis step of this process. As shown in Fig. 6, this process utilizes a steam reformer, TEC s TAF-X reactor, oxygen reformer, TEC s MRF-Z methanol reactor, and TEC s DME reactor. 

Partial Oxidation or Oxygen Reforming. The third.of the above processes available for producing hydrogen from hydrocarbons is that of partial oxidation. This relatively new process developed by The Texas Company is economically competitive with or superior to steam reforming because of the development in recent years of low-cost oxygen. About ten syn-... 

The oxygen-reforming process was first developed for use with natural gas as a fuel but also has been applied to light oils and heavy bunker-type fuel oils. The flexibility of the process with respect to fuels is particularly attractive since it is possible to establish plants needing hydrogen at locations where neither natural gas nor coal is economically available but to which fuel oils can be easily transported.
