Abstract

Hydrogenation of carbon‐^13^C dioxide over ruthenium‐on‐alumina catalyst at 300–400°C produced methane‐^13^C, which was passed with excess ammonia over platinum at 1000°C to give, after absorption of the product in sodium hydroxide solution, sodium cyanide‐^13^C in 90% overall yield. Methane‐^13^C‐d~4~ and methane‐d~4~ were prepared by reduction of carbon‐^13^C monoxide and carbon monoxide, respectively, with deuterium.

## Abstract The kinetic isotope effects in the reaction of methane (CH~4~) with Cl atoms are studied in a relative rate experiment at 298 ± 2 K and 1013 ± 10 mbar. The reaction rates of ^13^CH~4~, ^12^CH~3~D, ^12^CH~2~D~2~, ^12^CHD~3~, and ^12^CD~4~ with Cl radicals are measured relative to ^12^CH~
