The determination of Loss on drying

  Weigh a sample of approximately 2g (weighing accuracy 0.0001g),Record the weight of m,The sample was placed in a Petri dish constant weight (weight recorded as m0), the tile, the thickness of not more than 5mm, into the oven (As next dish cover removed) drying at 105-110 ℃ 3 hours.When removing, make sure the dish cover,be placed in a desiccator to cool, then weighed and the weight (including surface dish) m1.

Loss on drying in accordance with the following formula:

Where: 

         m-- sample, g

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.
