ChemInform Abstract: LIQUID‐LIQUID PARTITION COEFFICIENTS BY HIGH‐PRESSURE LIQUID CHROMATOGRAPHY
Chemischer Informationsdienst, 1975Lipid-water partition values can be rapidly and reliably measured by high-pressure liquid chromatography (HPLC) on bonded octadecylsialne supports. This method has been developed and applied to a family of hypotensive triaminopyrimidine 3-oxides. The measured column retention values for this class of compounds correlate well with the values calculated ...

Raman spectroscopy in liquids at high pressure
Chemical Physics Letters, 1973Abstract The pressure dependence of the reorientational correlation function for chloroform has been measured by analysis of the Raman 3019 cm − 1 A 1 CH stretching lineshape at 1, 1000, and 2000 bar and 23°C. These reorientational correlation functions were obtained using the method of spectral Fourier deconvolution introduced by Bratos.

Viscosity of liquid Fe at high pressure
Physical Review B, 2002Synchrotron x-ray radiography has been used to measure the viscosity of pure liquid Fe at high pressure and temperature in a large volume press. A probe sphere rising through liquid Fe at high pressure and temperature is imaged, in situ, allowing for the derivation of sample viscosity through a modified form of Stokes' equation.

Refractive index of liquids at high pressures
Critical Reviews in Solid State and Materials Sciences, 1983Abstract In this age of laser technology, the importance of studies on piezo– and elasto‐optic properties of liquids cannot be over-emphasized. In many applications such as acousto‐optic modulators, acoustic probes, high speed optical scanners and deflectors, etc., in the field of communications, a precise knowledge of the elasto‐optic coefficient of ...

High Pressure Vapor-Liquid Equilibrium
1993We saw in the previous Chapter, Section 13.4, that high pressure vapor-liquid equilibrium (VLE) involves systems where some, or all, components have low boiling point temperatures at atmospheric pressure, typically mixtures of hydrocarbons — alone or with some inorganic gases: N2, CO2, CO, etc.

High-pressure liquid chromatography on triacetylcellulose
Journal of Chromatography A, 1983Abstract Microcrystalline triacetylcellulose ( d p = 10–20 μm) was used for analytical liquid chromatography at pressures around 50 bar. 1,3,5-Tri- tert .-butylbenzene is proposed as a compound which is not retained on this sorbent. Thus, reliable information about porosity, linear flow-rates, u , and relative retentions become available for the ...

On shear stresses in liquids at high pressure
British Journal of Applied Physics, 1965A method has been developed by which experimental determinations may be made of the pressure and temperature limits of hydrostatic conditions in any liquid pressure transmitting media. Some experimental results for pentane, H62/56 oil and a polyphenyl ether are presented, and pressure-temperature diagrams are drawn for the last two.

High-Pressure Gas-to-Liquid Transducer
Review of Scientific Instruments, 1958A tramsduncer is described which can withstand differential overpressure of 20,000 psi in either direction, while retaining high sensitivity during balance. (A.C.)

Properties of Liquids at High Sound Pressure
The Journal of the Acoustical Society of America, 1947When sound of high amplitude is transmitted into a liquid by means of a mechanical driving device, the ultimate limitation to the power that can be transferred is cavitation or breakdown of the liquid under high internal stresses. A study of cavitation has resulted in establishing the following results.
