Benzene is about 2% soluble in HF under ordinary conditions but about 20% soluble at 50°. Oxygen, nitrogen, and sulfur containing organic compounds are in general very soluble in liquid hydrogen fluoride. 

Colorless hexagonal crystals density 1.846 g/cm at 20°C decomposes on heating to produce sodium and nitrogen also decomposes in vacuum soluble in water partially converting to hydrazoic acid, solubdity in water, 41.7 g/lOOmL slightly soluble in alcohol, 0.316g/100mL at 16°C soluble in liquid ammonia. 

Butadiene reacts readily with oxygen to form polymeric peroxides, which are not very soluble in liquid butadiene and tend to settle at the bottom of the container because of their higher density. The peroxides are shock sensitive therefore it is imperative to exclude any source of oxygen from butadiene. Addition of antioxidants like /-butylcatechol (TBC) or butylated hydroxy toluene (BHT) removes free radicals that can cause rapid exothermic polymerizations. Butadiene shipments now routinely contain about 100 ppm TBC. Before use, the inhibitor can easily be removed (247,248). Inert gas, such as nitrogen, can also be used to blanket contained butadiene (249). 

Potassium benzenetellurolate is stable for months under an atmosphere of nitrogen, but decomposes readily in contact with oxygen or moisture. The tellurolate is soluble in liquid ammonia, in acetone, and in tetrahydrofuran. The color of the solution in ammonia is orange1. 

Water is slightly soluble in liquid nitrogen. At -196°C (the boiling point of liquid nitrogen), the mole fraction of water in a saturated solution is 1.00 X 10 . Compute the mass of water that can dissolve in 1.00 kg of boiling liquid nitrogen. 

Properties Very soft, silvery metal. D 0.534 (20C), mp 179C, bp 1317C, Mohs hardness 0.6, viscosity of liquid lithium less than water, heat capacity about the same as water. Reacts exothermally with nitrogen in moist air at high temperatures high electrical conductivity soluble in liquid ammonia. 

At high temperature, sodium and its fused halides are mutually soluble (14). The consolute temperatures and corresponding Na mol fractions are given in Table 3. Nitrogen is soluble in liquid sodium to a limited extent, but sodium has been reported as a nitrogen-transfer medium in fast-breeder reactors (5) (see Nuclear reactors). 

Several methods of helium purification from nitrogen are used. The washing the concentrate with liquid hydrocarbons, particularly with propane, is based on abnormal helium solubility in liquid propane. There are also continued intensive studies and implementation works on helium purification using membranes [19,20]. The purification by washing does not, however give a product of a sufficient purity and efficiency of the diffusive separation on membranes is still too low. For these reasons, the basic process of helium denitrification is adsorption on solid adsorbents, mainly on active carbon. 

Ammonium Sulfate. Although an excellent nitrogen-sulfur fertilizer with good physical properties, ammonium sulfate is now outranked economically by ammonium nitrate and urea. Only about 4 percent of U.S. fertilizer nitrogen is furnished as ammonium sulfate. The chief reasons for the unpopularity of ammonium sulfate are its relatively low nitrogen content (21%) and its relatively low solubility in liquid fertilizers. At most U.S. locations, it is uneconomical to produce ammonium sulfate... 

Phosphine is a colourless gas at room temperature, boiling point 183K. with an unpleasant odour it is extremely poisonous. Like ammonia, phosphine has an essentially tetrahedral structure with one position occupied by a lone pair of electrons. Phosphorus, however, is a larger atom than nitrogen and the lone pair of electrons on the phosphorus are much less concentrated in space. Thus phosphine has a very much smaller dipole moment than ammonia. Hence phosphine is not associated (like ammonia) in the liquid state (see data in Table 9.2) and it is only sparingly soluble in water. 

Argon is two and one half times as soluble in water as nitrogen, having about the same solubility as oxygen. Argon is colorless and odorless, both as a gas and liquid. Argon is considered to be a very inert gas and is not known to form true chemical compounds, as do krypton, xenon, and radon. 

It would clearly be of interest to discover how far the nonane method can be used with adsorbates other than nitrogen. A study along these lines has been carried out by Tayyab, but a discussion of his rather unexpected results is best deferred until the role of fine constrictions has been considered (p. 228). Meanwhile it may be noted that the applicability of the technique seems to be limited to adsorptives such as nitrogen or argon which have negligible solubility in solid or supercooled liquid n-nonane. 

It follows that the applicability of the nonane pre-adsorption method for the evaluation of microporosity is restricted to adsorptives such as nitrogen which are used at temperatures far below ambient and which have negligible solubility in soUd or liquid nonane.
