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.
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.
