A mechanistic model for the kinetics of gas hydrate formation was proposed by Englezos et al. (1987). The model contains one adjustable parameter for each gas hydrate forming substance. The parameters for methane and ethane were determined from experimental data in a semi-batch agitated gas-liquid vessel. During a typical experiment in such a vessel one monitors the rate of methane or ethane gas consumption, the temperature and the pressure. Gas hydrate formation is a crystallization process but the fact that it occurs from a gas-liquid system under pressure makes it difficult to measure and monitor in situ the particle size and particle size distribution as well as the concentration of the methane or ethane in the water phase. 

After the period, the reaction was quenched by adding a solution of 1 M HC1 with vigorous stirring at 0 °C until no more ethane gas was generated. The white inorganic material was removed by filtration over a glass filter.

The first step of the chain extension reaction mechanism has been shown to b e etiolate formation, the by-product of which Is ethane gas. The nitrogen line should be attached to a large adapter to provide adequate venting of the gas. 

Note that the viscosity of the saturated liquid is equal to the viscosity of the saturated vapor at the critical point. The isobars above the saturation line give the viscosity of liquid ethane, and the isobars below the saturation line give the viscosity of ethane gas.

The solid line is a weighted average of the annihilation rates between 120 and 180 amagat. The broken line is the prediction for free ortho-positronium. The data are due to Sharma, Kafle and Hart (1984).

The heat of combustion of ethane gas, CtH. is 1561 kJ/mol. Assuming that 60% of the heat is useful, how many liters of ethane (S.T.P.) must be burned to supply enough heat to convert 50kg of water at 10°C to steam at 100°C ... 

Under an argon atmosphere, a solution of diethylzinc (1.0 m in hexane, 0.2 mL, 0.2 mmol) was added to the solution of the amino alcohol ligand prepared as above (64mg, 0.1 mmol) in THF (1 mL) at room temperature. After stirring for 30 min at the same temperature with evolution of ethane gas the resulting solution was used as a ca 0.09 m solution of 3.

In a sample of ethane gas at room temperature, the ethane molecules rotate millions of times per second, and their conformations are constantly changing. These conformations are not all equally favored, however. The lowest-energy conformation is the staggered conformation, with the electron clouds in the C—H bonds separated as much as possible. The interactions of the electrons in the bonds make the eclipsed conformation about 12.6 kJ/mol (3.0 kcal/mol) higher in energy than the staggered conformation. 

Ethane gas, C2H6, is present in small amounts in natural gas. 

Vigorous gas evolution (highly flammable ethane gas) and boiling take place during the addition.
