In one of these processes ( used by BASF ) the formic acid is removed from the water by liquid-liquid extraction with an organic base.
32.
Martin and Synge initially attempted to devise a method of performing a sequential liquid-liquid extractions with serially connected glass vessels that functioned as separatory funnels.
33.
With dissimilar properties, some collisions produce no extraction because the droplets bounce ", but with similar properties, some collisions produce coalescence and liquid-liquid extraction.
34.
Pioneered in Turner Valley, natural gas liquids extraction eventually became an important Canadian industry in its own right, as the story of its development illustrates.
35.
Shortly after the sulfinol process was implemented, sulfolane was found to be highly effective in separating high purity aromatic compounds from hydrocarbon mixtures using liquid-liquid extraction.
36.
Countercurrent distribution, therefore, is a method of using a series of vessels ( separatory funnels ) to separation compounds by a sequence of liquid-liquid extraction operations.
37.
Solid-liquid extraction based ambient ionization is based on the use of a charged spray, for example electrospray to create a liquid film on the sample surface.
38.
After performing liquid liquid extraction, a quantitative measure must be taken to determine the ratio of the solution s total concentration in each phase of the extraction.
39.
A typical modular process system for liquid liquid extraction includes processing equipment such as columns, reactors, heat exchangers and pumps, mounted within a strong structural steel frame.
40.
This is because it is not able to enter the tributyl phosphate / hydrocarbon organic phase used in the first liquid-liquid extraction cycle of the PUREX process.
