반응 단계
One gram of the catalyst used in Run No. 3 of Example 4 was mixed with 11.1 g. of quartz, and the mixture was charged to a tubular quartz reactor unit, as in Example 2. Following generally the procedure of Example 3, m-diacetylbenzene was passed through the tubular reactor at 650° C., 10.0 Torr total pressure, 9.1 Torr partial pressure of the diacetylbenzene and a contact time of 0.0041 second for 10 minutes on stream. The selectivity for the formation of m-diethynylbenzene and the total fractional conversion were 0.66 and 0.16, respectively. The other products in the reaction mixture besides diethynylbenzene and water were m-ethynylacetophenone, acetophenone, methylacetophenone, m-isopropenylacetophenone and m-vinylacetophenone. Based on additional runs, it was found that product distribution depended considerably on the contact time. Comparable results were obtained in the conversion of p-diacetylbenzene to p-diethynylbenzene following the procedure of this example.
