melting Flashcards
heat capasity during meleting
infinity
what are the melting point techniques?
capillary method
dsc
hot stage method
differential scanning calorimetry
- power compensation
2. heat flux
advantage of dsc
- simple
- need small sample
- rapid
uses of melting point
- identify the compund
- identify impurities
- indicate order of solubility
- determine compatability or incompatability of drug excipient combination
how to identify compound through melting point
- mixed melting point
what is definition of melting point?
the temperature where compound change from solid to liquid
the temperature where solid state of compund equilibrium with liquid state
