[52] and is caused by the disproportionation of the reaction chemistry of a-Si[O.sub.x]:H(i) into a more oxygen-rich suboxide.
The publication includes a detailed analysis of a process similar to CB&I Lummus OCT, where propylene is produced via metathesis (disproportionation) from ethylene and butenes, presenting key technical information such as process description, flow diagrams, heat and material balances, consumption figures, and major equipment list.
Furthermore, use of proton pump inhibitors can decrease the acid secretions in the stomach, thereby affecting the acidic disproportionation of nitrite to NO.
In addition, steric hindrance would favor termination by disproportionation as opposed to coupling which would also result in a decrease in [M.sub.n].
Therefore the rate of disproportionation of the activated complex is considered to be the slowest and hence the rate determining step.

Autotrophic methanogens utilize hydrogen as energy source for the reduction of [CO.sub.2] to methane; specialized genera of methanogens are also capable of inter- and intramolecular disproportionation of [C.sub.1] and [C.sub.2] carbon compounds (methanol, methylamines, acetate) to methane and CO2 (Boone et al., 1993).
