Melting Point In subject area: Physics and Astronomy Melting point refers to the temperature at which a solid substance changes into a liquid state. In the context of organic compounds, the melting point is used as an important criterion to evaluate structural changes. It can vary significantly ...
For a mixture, the initial melting point is close to the melting point of the lightest compound in the mixture, while the initial freezing point is close to the freezing point (or melting point) of the heaviest compound in the mixture. Since the melting point increases with molecular weight,...
Batchelor and Foster 1 found, by examination of the vapour pressure – temperature curves, that dioxan adsorbed on a ferric oxide gel of pore radius 100 A. melts sharply about 6° C. below the normal melting point of the bulk liquid. During a recent investigation of the sorption of amines...
(Solid + liquid) phase equilibria for N,N-dimethylacetamide + tetrachloromethane) have been obtained from time-against-temperature warming curves. Standard enthalpies of melting of three pure components and standard molar enthalpies of formation of 14 solid intermolecular compounds have been calculated ...

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...
specific goal that you should be able to predict relative physical and chemical properties by the end of the course. For example, you should be able to tell which of a pair of related compounds has the higher boiling point. The following information should begin to help you meet this goal....
The present invention relates to compositions comprising water-soluble alkoxylated polyamines with a low melting point. More specifically, the present invention relates to compositi
