A low-melting solid is used as organic solvent for liquid-liquid extraction at elevated temperatures followed by solidification and decantation of the aqueous phase.

The presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. Moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. The aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coeff...

In the present survey some important trends in the high pressure thermodynamics of fluid mixtures of non-electrolytes are reviewed. First the pressure dependence of excess functions such as the excess Gibbs energy GE, the excess enthalpy HE, the excess entropy SE and the excess heat capacity CE is discussed. It can be obtained from the knowledge of the excess volume yE as a function of pressure...

Isoprenol (3-methyl-3-buten-1-ol) is an important intermediate in the chemical industry and used, for example, production of various scent flavor chemicals. produced from aqueous formaldehyde isobutene separated by distillation mixtures containing formaldehyde, water, process. As forms oligomers with both water isoprenol, these are complex reacting systems, which not easy to separate. Hence, un...
