Product distributions for the near thermal translational energy (less than or equal to 0.1 eV) reactions of CH/sub 3//sup +/ and CD/sub 3//sup +/ with propionaldehyde, propylene oxide, trimethylene oxide, and allyl alcohol are reported and compared to previous results for acetone. With the exception of allyl alcohol, each of the C/sub 3/H/sub 6/O isomers exhibits a reaction pathway with CD/sub 3//sup +/ leading to formation of a CD/sub 3/OCH/sub 2//sup +/ ionic product. Other ionic reaction products include C/sub 2/H/sub 5//sup +/, CH/sub 3/O/sup +/, C/sub 3/H/sub 5//sup +/, C/sub 3/H/sub 7//sup +/, CH/sub 3/CO/sup +/, C/sub 3/H/sub 5/O/sup +/, and C/sub 3/H/sub 6/O/sup +/. The results are generally consistent with CH/sub 3//sup +/ attack at the oxygen atom and formation of a short-lived intermediate adduct in approximately 80% of the reactive collisions; less important reaction channels include charge exchange, hydride transfer, and attack at sites other than oxygen.
