At --75 and 0 deg C on a chromium oxide gel catalyst, the addition of deuterium to ethylene forms substantially pure ethane-1,2-d/sub 2/. At --11 deg C, about 1% alkane-d/sub 3/ and -d/sub 4/ contaminates the alkane-1,2-d/sub 2/ resulting from deuterogenation of propylene and 1-butene. At 40 deg C, cyclopentene gives about 2% and 1-hexene, about 5% d/sub 3/ and d/sub 4/. 2- Pentene leads to considerably more d/sub 1/ and d/sub 3/ and d/sub 4/ than 1- hexene. Increase in temperature of deuterogenation, particularly above 85 deg C, results in wider isotopic distribution patterns and, at 150 deg C, only about half of the products from 1hexene, 2-pentene and cyclopentene is alkane-d/sub 2/. 1-Hexene in a stream of nitrogen is extensively isomerized on chromia at 200 deg C. At 125 and at 200 deg C with partiaily activated cataltsts which give incomplete deuterogenation, the unreacted olefin is both isomerized and isotopically exchanged, but, at 50 deg C and below, the unreacted olefin is negligibly isomerized or exchanged.
