        Influence of time, distillation with H₂, CH₄, or N₂, 2-stage treatment for liquid products, and partial combustion with O₂ have been studied at high and low pressures for C₂H₄.  Quantitative pure thermal dehydrogenation to C₂H₂ depends upon high temperature, a controlled brief time, low pressure, and distillation with H₂.  The dehydrogenation of C₂H₆ proceeds by stages, and yields of either 86% C₂H₂ or 72% C₂H₄ are obtainable by the control of similar factors as with C₂H₄.  Includes brief review and bibliography.
