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.

 

Determination of iron content

  Preparation of standard iron solution

  Weigh ammonium iron(III) sulfate [FeNH4(SO4)2·12H2O] 0.863g .Placed in 1000mL volumetric flask,

 add water to dissolveand add sulfuric acid 2.5mL.Diluted with water to the mark, shake, as the stock 

solution.

   Before use, exact amount of stock solution 1mL, placed in 100mL flask, diluted with water to the 

mark and shake.

  Weigh 1g sample, placed in a crucible.Adding sodium carbonate 2g and mixed.Burning at 740 ℃,

the residue is dissolved in dilute hydrochloric acid 15ml , displacing 50mL Nessler colorimetric tube ,

 add dilute hydrochloric acid 4mL and ammonium persulfate 50mg , Diluted with water to make into 35mL, add 30% ammonium thiocyanate solution 3mL, plus the amount of water diluted into 50mL, shaked.

 If the color, take 1mL standard iron solution into 50mL Nessler colorimetric tube, add water to 25mL,4mL dilute hydrochloric acid and 50mg ammonium persulfate , diluted with water to 35mL, then plus 30%

 ammonium thiocyanate solution 3mL, plus the amount of water diluted into 50mL, shake comparisons.

 

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:

Guanidine hydrochloride    CAS NO 50-01-1   99%

Where:

         m-- sample, g

       m0-- dish, g

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

 

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 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 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 insolubles

 Principle:

   Sample was dissolved in water and the insoluble matter was filtered off, the filter residue was washed 

with water, so that the sample body is completely separated, dried and Referred to the mass of the

 insolubles.

Procedure:

   A predetermined amount of the sample, dissolved in a predetermined volume of boiling water, 

cooled to room temperature, and filtered with the glass filter crucibleat of 105±2℃ constant weight , 

washed with hot water to the residue adsorbed on the filter cake is completely washed off , in an 

electric oven at 105±2℃ dried to constant weight.

Results:

  Quality of water insolubles percentage is calculated as follows:

Guanidine hydrochloride    CAS NO 50-01-1   99%

 Where:

     X --mass percentage of insoluble matter,%

     M2 -- quality of residue and glass filter crucible, g

     M1 -- quality of the glass filter crucible,g

     M -- quality of the sample,g
