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 residue on ignition
First the Griddle was burning 30 minutes at 600 ± 50 ℃, cooled and
then weighed on a silica gel drier.Taking 1g sample was placed in a
crucible and weighed, with 2ml sulfuric acid (5.5ml98% sulfuric
acid diluted to 100ml) wetting the sample which was slowly heated
until the sample completely low zoom.Cooling,using 2ml sulfuric
acid (5.5ml98% sulfuric acid diluted to 100ml) to wet the sample,
which was slowly heated until no white smoke, and then placed at
600 ±50℃ calcined to obtain the residue, to ensure that the entire
process does not produce white smoke.Cooling Griddle silica gel
dryer and then weighed to calculate the mass of the residue.
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
