Temperature saturated

Values converted and mostly rounded off from those of Goodwin, NBSIR 77-860, 1977. t = triple point c = critical point. The notation 3.O.—9 signifies 3.0 X 10 . Later tables for the same temperature range for saturation and for the superheat state from 0.1 to 1000 har, 85.5 to 600 K, were published by Younglove, B. A. and J. F. Ely, J. Fhys. Chem. Ref. Data, 16, 4 (1987) 685-721, but the lower temperature saturation tables contain some errors. 

The overhead purity is specified as X/ ) = 0.95. The reflux temperature is the bnbble-point temperature (saturated reflux), and the external-reflnx ratio is set at 71 = 4.5.

Trans-4-Octene oxide 1885 (1.2 mmol), then hexamethyldisilane 857 (1.8 mmol) in 5 mL HMPA, are added, at 65 °C under argon, to 0.2 mmol potassium methox-ide in 10 mL anhydrous HMPA. After 3 h stirring at 65 °C and cooHng to room temperature saturated aqueous NaCl solution is added to the reaction mixture, which is then extracted with pentane. The pentane extracts are combined and dried with Na2S04 and analyzed by vapor phase chromatography (VPC) to reveal the formation of 99% cis 4-octene 1887 [103] (Scheme 12.71).

The solution is cooled to room temperature, saturated with sodium chloride (about 170 g. is required), and extracted with ether in a continuous extractor (Note 2). The extraction time is 15-20 hours. The ether extract is adjusted to a volume of 1 1., dried over 4-5 g. of sodium hydroxide pellets, and filtered, and the ether is removed by distillation from a steam bath. The residue crystallizes on cooling. The yield of dark red crystals melting at 61-63° is 39-41 g. (83-89%). 

Values of the low-temperature saturation magnetic moment of ferromagnetic substances represent the maximum component of the atomic magnetic moment in the field direction for example, for spin alone the value in Bohr magnetons is 2S, whereas the magnetic moment obtained from the paramagnetic susceptibility is 2 /S(S + 1). 

To a solution of 2,3-O-isopropyIidene-D-glyceraldehyde (12.6 g, 97 mmol) in furan (20 mL), chloroacetic acid (5.7 g, 60 mmol) dissolved in furan (20 mL) was added and the mixture was refluxed for 8 h. After 12 h at room temperature saturated aqueous NaHCOj solution (50 mL) was added and the product was extracted with ether (3 x 100 mL). Combined ether extracts were dried (MgS04), concentrated to dryness, and the residue was chromatographed on a silica gel column with light petroleum-ether-methanol (6 4 0.5) to yield If ,2ft- and lS,2ft-l-C-(2-furyl)-2,3-0-isopropylidene-glycerols 1 (95 5, 7.0 g, 36.5%). 

Dolomite Equilibrium. Figure 2 is a plot of the ion product, (Ca2+) (Mg2+) (C032 )2, as a function of temperature. Saturation of lake waters with respect to dolomite is similar to the results for calcium carbonate. The same general conclusions are apparent. Dolomite tends to be saturated with respect to lake water at 14°C. 

To deposit amorphous silica at room temperature saturation concentration of about 100 to 150 ppm dissolved silica must be reached138-140. These fluctuations are due to slight pH effects on solubility (Fig. 16). 

The operation pressures depend on the temperature (saturation point) P T. During the gas handling process (e.g. liquefaction), pressures can be relatively high at very low temperatures, the storage tanks are almost atmospheric (50 to 350 mbarg). 

EuRu4Sbn is metallic and becomes ferromagnetic for temperatures below 3.3 K (Takeda and Ishikawa, 2000b). The low temperature saturation moment is about 6.2/xb, 89% of the Eu+2 value. Low temperature heat capacity measurements indicate that the magnetic entropy removed due to magnetic order is also only about 90% of its expected value (Rln8). It is likely that the lanthanide site is not completely filled in this compound although mixed valence behavior can not be ruled out with the available data. 

W = initial weight or dry weight, depending upon whether 9 the per cent initial or, the per cent dry weight were desired and the factor of 218 is the room-temperature saturation-magnetization of iron. 

Recent work reveals that SCC occurs only in hot MEA solutions when the electrochemical potential of the steel surface is more negative than -700 mV vs a silver-silver chloride electrode. The tendency for SCC increases with an increase in solution concentration and in temperature. Saturating the hot MEA solution with hydrogen sulfide makes the potential of the steel more positive (i.e., decreases the tendency for SCC). This latter result raises a question about the practice of some operators who require stress relief only for steels exposed to amine solutions containing hydrogen sulfide. 

As indicated above, at low fluences and low temperatures, essentially all non-reflected hydrogen ions incident on a carbon surface are retained [8,9]. However, once the near-surface has been saturated, very nearly 100% of the incident hydrogen is re-emitted from the surface. At 1 keV and room temperature, saturation of the implantation zone will occur at 2 x 1021H+/m2s [9,18]. At higher temperatures, saturation will occur at lower fluences, as trapping levels are reduced, see Sect. 10.2.1.
