Determination of melting point

?? Instrument:

?? Micro melting point apparatus WRS-2A, Melting point tubes

? Determination of step:

Open switch, stable 20min.

First set the starting temperature than the melting point of the low 10 ℃, heating rate 2 ℃ / min.

The sample was grind as fine as possible and load in a clean, dry melting point pipe ,until the sample was compressed into about 1cm high .When the actual temperature reaches the set temperature and stabilized . Inserted into the capillary with the sample, the simultaneous determination of three.
