Reactions between D/sub 2/ amd methyl radicals obtained from the reaction CH/sub 3/I + NaI = CH/sub 3/ + NaI were studied. The scheme of the installation is shown. The spectroscopic analysis revealed the content of the variously deuterized methanes but the absolute methane quantity was not determined. The experiment used electrolytically obtained D/sub 2/O purified from admixtures, refined CH/sub 3/I, and chemically pure sodium. It was revealed that the content of deuterium in the formed methanes varies considerably during the precipitation on the surface of metallic sodium vessels, and that the relation of methane content to the temperature depends on the type of sodium surface. At room temperature the content of deeply deuterized methames (CD/sub 4/ , CD/sub 3/, and CH/sub 2/D/sub 2/) in the sodium mirror coated vessels is 5 to 6 times higher than in pure quartz; with the increase of temperature the content of deuterized methane drops. In the case of sodium drops, the surface reaction is negligible, however, the methane from the radicals CH/sub 3/, formed in the volume, contain more deuterium than in the case of the sodium mirror. The maximum deuterization is at 70 to 80 deg ; at higher temperature the CH/sub 4/ and CH/sub 3/D prevail. The light methane CH/sub 4/ does not exchange with the D/ sub 2/ in the presence of the sodium mirrors nor the drops. (R.V.J.)
