3.2.1.1 Melting point Melting point is a valuable criterion of evaluation of any changes in the structure of an organic compound. The formation of prodrug is characterized by a change in melting point which is generally significantly different from that of either pure drug or lipid. The addition...
In the following pair, which has the higher melting point and why? {eq}KCl {/eq} or {eq}CaF_{2} {/eq} Melting Points of Ionic Compounds: Although ionic compounds have relatively high melting points and relatively very high boiling points, not all ionic compounds have...
At the melting point, the solid and the liquid form of the substance exist in equilibrium. Answer and Explanation: The Magnesium oxide(MgO) and Calcium sulfide(CaS) both are ionic compounds. As we go down in a group in the periodic table the size of the element......
remelting in a vacuum environment not only prevents contamination of steel, non-ferrous active metals and alloys by the outside atmosphere, but also reduces harmful gaseous and low-melting-point metallic impurities in steel, non-ferrous active metals and alloys, by improving the purity of the re...
This application gives the use of potentiometric sensor in the determination of the titer value without changing the method. 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 ...
chloride or anhydride of an aliphatic acid; and wherein the polyester has a melting point in the range of from about 140 to about 185° C. 10. The bicomponent fiber of claim 9, wherein the core portion is a polymeric material selected from the group consisting of polyethylene terephthalate...
As a furnace for the melting operation, we use, e.g., an electric resistance furnace with tamped carbon lining, and one or several graphite electrodes. The components of the silicate melt are ignited by an electric arc, and are then heated to a temperature above the melting point of silico...
The modifled melting point of the fcc CaF2 is in the range of 1650{1733K at 0GPa. All these results are well consistent with the available experimental data and other theoretical results. We also obtain that the melting temperature of high pressure phase is 990{1073K at 10GPa. Moreover,...
