Method for determining the solubility of organic compounds in supercritical carbon dioxidePROBLEM TO BE SOLVED: To obtain a solubility close to an experimental value based on only the melting point and the structural formula of an organic compound without the necessity to conduct a measurement or an...
Summarize the physical properties of ionic compounds, nonpolar covalent compounds, polar covalent compounds, and covalent solids. Which is more important in determining a compounds melting point, its polarity or its formula weight? Does the bonding chara...
The term "petroleum" as used herein includes crude oils, residual oils, hydrocarbons, heteroatom compounds normally found as constituents in crude oils and the fractions derived from any of the above. Thus, there is provided a method for determining the tendency of oil containing asphaltenes to ...
22,23,24], and within the past two decades estimating environmental concentrations using specifically silicone is becoming more common [25,26,27,28,29,30]. Using established rate constant-based equations derived from Fick’s first law of diffusion for compounds in any phase of uptake...
Faba bean (Vicia faba L.) is an important protein-rich fodder crop, which is widely cultivated in temperate areas. However, antinutritional compounds such as condensed tannins, limit the use of this protein source in monogastric feed formulations. Previo
Methods requiring significant amounts of human skill and/or trial and error merely to select effective initial compounds are expensive to run in house and are not easily provided as a service to outside institutions. Thus, there remains a continuing need for novel methods and/or systems for ...
The measured values of below 0.2 W/m °C indicate very low thermal conductivity of the amorphous compounds, within the range of organic liquids and low conducting polymers. Keywords: thermal conductivity; amorphous; glass; indomethacin; celecoxib; DSC; small molecule Graphical Abstract...
Fourier Transform Infra-Red (FTIR) spectroscopy analysis was also used to determine how the composition of the organic compounds (in term of the functional groups) present in the CTP changed during the transition from the liquid to the solid paste at the baking isotherm temperature. 2. Materials...
During heating Ti-Cu intermetallic compounds form at the solid/liquid interface which impede diffusion of copper into the base metal but quickly consume to pure Cu foil. Temperatures above the melting point of the Ti2Cu-TiCu eutectic (960 °C) are needed before significant liquid phase forms ...
Considering other factors that determine the formation of solid solution phase, it has been identified that: (i) high melting point of the metal has a superior influence on the formation of topologically closed packed phases (TCP) solid solution phase and (ii) elements with large electronegativity...
