Dioxygen difluoride (O 2 F 2 ) was produced directly in the liquid phase at temperatures above −154°C. An O 2 /F 2 gas mixture was heated to 700°C and was then rapidly cooled on the outer surface of stainless steel tubes. The tubes were refrigera

Sulfur isotopes were separated in 1.07 and 1.50-m experimental packed distillation columns at cryogenic temperatures under total reflux. The 32S/34S ratio at column top was as much as 19% different from the bottom ratio. The 32S/33S separations were

Silicon isotopes were separated by distilling silicon tetrafluoride in a 150-cm packed column at temperatures of 189–206 K. The data show a reverse isotope effect with heavy isotopes more volatile in this temperature range. At total reflux, the max

A process has been developed to provide isotopic feed to a nitric oxide isotope distillation plant. Central to the process is the isotopic chemical exchange of NO and nitric acid in countercurrent flows in a 3-in. diameter packed column. An isotopica

The feasibility of separating carbon isotopes by absorptive distillation has been studied for CO absorption by cryogenic solvents. Phase equilibrium, isotopic separation, and mass transfer data were taken between 77.4 and 114.3 K for the following so

The deuterated methanes, 13CD4 and 12CD4, are useful as tracers for long-range (>500 km) atmospheric transport. They are easily synthesized and released. Sampling is accomplished by collecting about 330 l of air and chromatographically separating the

Five circuit functions required in a television (TV) receiver - namely, the sync separator vertical take off, horizontal oscillator, automatic frequency control (AFC), automatic phase control (APC), and a noise blanking circuit - have been successful
