Get safe, efficient fracture stimulation of your low-pressure, underpressured, and water-sensitive formations with VaporFrac™ services from Baker Hughes. VaporFrac services use an ultra-lightweight LiteProp™ proppant slurry. The LiteProp slurry combines an ultralightweight proppant with an enviro...
(21.4 mg, 0.031 mmol, 5%) was added, and then frozen and vacuumed three times, oxygen was removed. The reaction mixture was heated to 80 °C and stirred for 24 h under argon. After removal of the solvent under reduced pressure, the residue was extracted with CH2Cl2and H2O...
below 0.1% of the saturation vapor pressure of an organic solvent21. Thus, development of new types of optical organic vapor sensor with alternative mechanism to replace traditional solvatochromic shift type represents an important and highly demanded issue to improve the sensitivity of optical sensor....
Tetrahydrofuran (THF) is frequently used as a thermodynamic promoter in the development of hydrate-based technique, which can reduce the hydrate formation pressure, especially when methane or hydrogen exists. However, it is a hard work to describe accurately the phase behavior of THF-water system ...
The early growth stage of vapor bubble in degassed water shows a completely wetted bubble base with the microlayer, and the bubble does not depart from the surface due to reduced liquid pressure in the microlayer. Using experimental data and numerical simulations, we obtain permissible range of ...
Parameters: P /Pa Pressure Variables: x 1 /- Mole fraction of component 1 in liquid phase, T /K Temperature, y 1 /- Mole fraction of component 1 in vapor phase Method: Direct measurement of T and y 1 at variable x 1 and constant P Chemical substances in this chapter: Element System...
Moisture vapor permeable backing materials having a moisture vapor permeable pressure sensitive adhesive are disclosed by Hodgson in U.S. Pat. No. 3,645,835. The backing materials disclosed therein are synthetic polymers which are continuous and nonpermeable to liquid water. The adhesive materials ar...
which may be distilled over a temperature range of about 183-186° C. at a pressure of 40 millibars. Because the volatilities and reactivities of these three alkylaluminum alkoxides are similar, the mixed reaction product may be used as a reactant in CVD processes without further separation ...
