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 KF

Use MA-1 intelligent Carle Fischer moisture tester to measure water content

Detection of heavy metals

The meaning of heavy metals of this act is under the specified experimental condition, which can coloration effects with sodium sulfide or thioacetamide .The glasses of preparation or storage is not allowed to contain lead.

5.8.1 Reagents

a) Lead dinitrate:1μg/mL

b) Sodium hydroxide :10%(m/v)

c) Sodium sulfide :10%(m/v)

5.8.2 Preparation of lead standard solution

Weigh lead dinitrate 0.1599g ,relocated to 1000mL volumetric flask, plus nitric acid 5mL and water 50mL, diluted with water to the mark , shake, as the stock solution.

5.8.3 Determination of step

Before use, the exact amount of stock solution 1mL, relocated to a 100ml volumetric flask, dilute with water to the mark, shake, limit the use of the day .

Weigh sample 1g, after adding sodium hydroxide solution 5mL and 20mL of water to dissolve, set Nessler colorimetric tube, add 5 drops of sodium sulfide , shake , compared the color with 5mL lead standard solution after the same treatment, not deeper.
