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 PH


Weigh a certain amount of samples into test tube, add a certain amount of water, shake and dissolve, determination of the pH used have been calibrated pH meter.


The determination of UV absorbance


  A certain amount of the sample was weighed to the nearest 0.0001g, into 10ml volumetric flask, after constant volume with pure water, at a specific wavelength by 2cm cuvette was measured by UV spectrophotometer.


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


       m0-- dish, g


          m1-- After drying the quality of the sample and the dish, g
