Cis-stilbene is a liquid at room temperature (melting point: 5–6 °C (41–43 °F)), while trans-stilbene is a crystalline solid which does not melt until around 125 °C (257 °F), illustrating the two isomers have significantly different physical properties. [5] [6]
Z)-Stilbene has a melting point of 5–6 °C (41–43 °F), while (E)-stilbene melts around 125 °C (257 °F), illustrating that the two compounds are quite different. Uses [ edit ]
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.
