Cobalt-catalyzed oxidations in volumetrically expanded liquids by compressed gasesOxidations of hydrocarbons, cycloalkanes and alkenes, arylalkanes, and a variety of other organic substrates are accomplished by
However, it is also evi- dent that the lack of spreading of MAC blend cannot be attributed solely to its higher viscosity. An alternative hy- pothesis was that the MAC additive prevented spreading by increasing the surface tension of the blend; however, this possibility was discarded since ...
In general, CXL can be considered a switchable solvent technique found midway between pressurized liquids and compressed CO2 by increasing the amount of CO2 (Herrero et al., 2017). Show abstract This work reports the extraction of spent coffee grounds (SCG) oil using supercritical CO2 plus ...
The compressed gas is cooled and liquefied inside the condenser (1 → 2) and starts back the cycle again. The choice and the feasibility of this operation depend on the temperature levels at which the different tasks have to be performed: the working fluid should be chosen by consequence. ...
The compression at break of poly(VEtImBr) was 36.0 ± 8.3% and 28.6 ± 2.8% of poly(VBImBr), whereas poly(VBImCl) could only be compressed to 7.8 ± 3.6%. This trend in the compression measurements can be explained due to the length of the alkyl chain. The longer the alkyl chain ...
the size of a bellows cannot be varied in its entirely compressed positi~n. Accordingly only the bellows which for the moment is expanded will be influenced by the variations of volume of the measuring liquid, whence a greater volume of measuring liquid will flow from one bellows to the other...
24. A method as claimed in claim 23, wherein said expanded vapor is compressed prior to cooling in heat transfer relationship with said impure liquid to form a second vapor at a predetermined pressure corresponding to a predetermined temperature differential between said compressed second vapor and ...
compressed air is used to continue to hold the valve rod in its open position against the action of the spring. Now only a small amount of the liquid to be added can flow through the central outflow opening into the vessel to be filled. As soon as the correct weight has been obtained...
These foams may then be shaped into sheets. These sheets may optionally be compressed, e.g. continuously through pressure nips, into a thin state and wound into rolls. Compressible sheets can retain their relatively thin compressed state until unwound, applied as desired, and either heated above...
described concept cannot only be used underwater however. For example, cyclists or mountain climbers may also benefit from the fact that they are provided with drinkable liquid in such a simple manner. The pressure container110is configured to be externally pressure-tight for an overpressure ...
