Procedure

In Example 5, hydrogenation reaction was conducted under the same condition as Example 1 for THF diluted solution concentration of the substance to be reduced, its flow rate, and hydrogen 9 flow rate, using 1,2-diphenylacetylene as the substance to be reduced. The reaction time was within five minutes. The analytical result of the reaction product by 1H-NMR showed almost complete hydrogenation of 1,2-diphenylacetylene, and 1,2-diphenylethane was obtained at about 100% yield (See FIG. 6.).
