parahydrogen by the mechanism below. Turkevich and Selwood (68) have
examined the conversion on the solid free radical a, é-diphenyl-B-picryl hydrazyl.

Hydrogen Aircraft Technology
If parahydrogen was used, a (|> of 1 1 or 12 would be required for air liquefaction
instead of the (t> = 8 which is represented. The heat sink capacity of subcooled
hydrogen is shown in Figure 5-9 for two levels of pressure. As shown, a major ...

The parahydrogen was obtained in liquid phase by converting normal hydrogen
using catalyst; the purity of parahydrogen was estimated to be greater than 99.9
%. The crystal was grown at a temperature of 15 K under a pressure of 30 atm.
