Applying a distillation tower, more than 99% phenol is recycled by azeotropic batch fraction. The reflux ratio is optimized to 3 when a fraction column with ten theoretical perfect plates is used. Comparatively, the simple distillation gives dissatisfactory remo...
difluoroethane or trifluoroethylene, to a process for removing water from solutions by azeotropic distillation by means of these compositions and to a process for producing a hydrofluoroalkane in which water is removed from the mixture of reaction products by azeotropic distillation by means of these...
Determination of the Water Content of Wood and other Substances by means of Ternary Azeotropic MixturesIT is peculiarly difficult to dry certain substances and to determine the water in them because (a) if liquids they may form inconvenient mixtures of constant boiling point (azeotropic) with water...
tical chemicals, vitamin, and other branches of the industry of fine organic synthesis it makes sense to perform this process batchwise. At the present time, for example, a batch process of the dehydration of isopropanol with the elimination of the water in the form of the heteroazeotrope with...
Novel Methods to Separate Azeotropic Butanol-Water Mixtures without the Need for Extractive Distillation or Pervaporative Membrane SeparationKareemuddin Shaik
10. The process according to claim 5, wherein said mixture comprises at least 70 wt/% of tri, tetra and/or higher polyalkoxy functional group-containing compounds and the amount of water is in the range of 1 to 50 times by mole of the total alkoxy groups in the mixture, whereby said...
Lorlatinib (PF-06463922) is a next-generation small-molecule inhibitor of the orphan receptor tyrosine kinase c-ros oncogene 1 (ROS1), which has a kinase domain that is physiologically related to anaplastic lymphoma kinase (ALK), and is undergoing Phase
of the removal mechanism of alcohol-enhanced organic compounds is that alcohols can reduce the surface tension of the contaminated water, resulting in Marangoni convection, thereby enhancing mass and heat transfer. The addition of alcohol may also reduce the azeotropic temperature of the system and ...
The heat transfer coefficient (HTC) and pressure drop were obtained at a mass flow rate of 0.04–0.2 kg/s and a water inlet temperature of 310–330 K. The results show that the HTC and the drop in the pressure of the corrugated tubes both obviously increased compared with a smooth tube...
It is often possible to separate and analyze water quantitatively by azeotropic distillation of the water with benzene, toluene, or other liquid in the form of an azeotropic mixture; after the separation of the mixture upon cooling, the volume of sepa-rated water is measured. Use in industry....
