LAST year, in a letter in Nature 1 , Foster and Hammick pointed out the similarities of the curves of the melting points against the length of the hydrocarbon chain, with a minimum in C 5 , for both the alkylanilines and alkylnaphthols. They seem not to be aware of similar comments ...
【Melting Point】 135 【Boiling Point】 444 【Vapor Pressure】 2E-8 (25 C) 【Density】 1.119 g/cm3 (151 C) 【pKa/pKb】 13.50 pKa 【Partition Coefficient】 4.24 【Heat Of Vaporization】 72.8 kJ/mol 【Heat Of Combustion】 -8263 kJ/mol ...
The present invention relates to a process for the modification of the physical properties (viscosity, melting point, etc.), of colloidal substances and more specially to a process for the modification of the physical properties of organic isocolloids. By "isocolloids" 'or "isocolloidal substances...
The use of heater DH100 for complete removal of CO2 after the first equivalence point leads to very high precision results. Depending on instrument type, manual operation and method, changes can be made using the given method as a reference. Reaction: 1) 1st EQP: H2SO4 + Na2C03 → NaHCO...
2-naphtholaromatic aldehydesacid-catalysisEquations that allow determining the melting point, change in volume, and other thermodynamic parameters of melting of polymers at high pressure are proposed based on the statistical-thermodynamic theory of melting of polymers. The good agreement of the ...
