Mercury hydrogen

Typical concentration-time relationship for experimental runs. Temperature, 26°C pressure, 746 mm of mercury hydrogen flow, 30.7 x 10 5 mole/sec catalyst weight, 0.975 g stirrer speed, 1100 rpm slope, 13.7 x 10 5 mole/liter/sec. 

Effect of catalyst weight on rate of reaction. Temperature, 25 °C pressure, 748 mm of mercury hydrogen flow, 31.3 x 10 5 mole/sec stirrer speed, 1000 rpm. 

These compounds, alk-l-enylmercuranes as they may be known to pedant and pedagogue, are very unstable at room temperature even in solution, decomposing to mercury, hydrogen and the corresponding butadiene in a matter of minutes. Pressurisation of sealed containers would result. 

Example 1.2 Table 1.3 lists the specific volumes of water, mercury, hydrogen at l(atm), and hydrogen at lOO(atm) for a number of temperatures on the International Practical Temperature Scale. Assume that each substance is the fluid in a thermometer, calibrated at the ice and steam points as suggested at the beginning of this section. To determine how good these thermometers are, calculate what each reads at the true temperatures for which data are given.

Methods which realize mercury-hydrogen exchange in organomercurials include homolytic decomposition in solvents capable of hydrogen atom transfer, protonolysis by protonic acids and reduction. 

The present review considers recent advances in mercury-hydrogen interchange by protonolysis and reducing agents, and especially metal hydride demercuration. 

However, the alkenylmercury acetate (10) undergoes mercury-hydrogen exchange with HCl with inversion. A mercurinium ion intermediate has been proposed, where the vicinal phenyl groups provide the driving force for isomerization (Scheme 22). ... 

Hydrogen Oxidation Kinetics. Shea et al. (22) studied the kinetics of methane fermentation by an enrichment culture of lithotrophic (autotrophic) hydrogen oxidizing methanogenic bacteria at 37 °C. Reported values of the kinetic coeflScients are as follows (1) Y = 0.043 mg volatile suspended solids per mg of hydrogen COD removed, (2) b = —0.009 day"S (3) k = 24.8 mg hydrogen COD removed per mg volatile suspended solids per day and (4) Ks = 569 mm of mercury, hydrogen pressure. 

Kwan and Izu (23) investigated the chemisorption of hydrogen on carefully reduced copper, with results strikingly different from those in the earlier work discussed above. Kahlbaum s extra fine copper and other samples of an equally high grade of purity were reduced at 450°C. with hydrogen at a pressure of several centimeters of mercury. Hydrogen...
