ABSTRACT:

The work on the project during the last quarter has focused on the continuation of in-situ trapping reactions, ethyliodide being the trapping agent this time, and on the preliminary experiments using the model organometallic complexes. Both of these thrusts added to our understanding of the system and led to the decisions of extending the experimental work, for the future studies, to the use of (1) labelled compounds and GC-MS analysis for the in-situ reaction work, and (2) supported organometallic complexes for the model complex trapping reactions. CO hydrogenation reaction was carried out on RuKy catalyst. The experimental system, catalyst preparation and pretreatment conditions, and the reaction conditions were the same as those used for the CH sub 3 I trapping experiments reported in a previous quarterly report, for the same catalyst. During the C sub 2 H sub 5 I trapping experiments the CO stream was diverted through a saturator containing C sub 2 H sub 5 I which was kept in a Dewar flask. The temperature of the C sub 2 H sub 5 I was adjusted to maintain a 1% by volume of C sub 2 H sub 5 I concentration in the gas phase. Effluent gas analysis was carried out on-line using a Perkin-Elmer Sigma 300 GC, fitted with TC and F1 detectors and a 12 m.  SP-1700 column maintained at 343 K, as before. As with CH sub 3 I, C sub 2 H sub 5 I also produced significant changes in the product distribution of the F-T reaction. The most striking observations made during the C sub 2 H sub 5 I trapping experiments are summarized briefly. (ERA citation 12:035317)
