Determination of melting point
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.
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:
m-- sample, g
m0-- dish, g
m1-- After drying the quality of the sample and the dish, g
