Reaction of Co with Synthesis Gas

483 K after 1215 min. The apparatus was cooled to room temperature, and the headspace gases and liquid phase analyzed by GC, giving the results shown in Table 15.1. Gas-phase products were identified by comparison of their retention time with authentic samples. Liquid-phase products were identified by retention time comparison and GC-MS. The recovered liquid phase was pale blue-green with most of the metal collected in a sticky mass. 

A 15 ml sample of the slurry described in Method 1 was treated with 1060psi of synthesis gas (2.4 1H2—CO) at 296 K. The pressure decreased to 985 psi within 0.5 h and remained constant over the succeeding 0.5 h. The reactor was heated to about 470K and kept at that temperature for 427 min. A sample of gas for GC and GC-MS analyses was removed at this time, giving the results listed in Table 15.1. GC-MS indicated that small amounts of formaldehyde, acetaldehyde, propanal, and acetic acid were also formed.
