The chemical compound trichloroethylene is a halo carbon commonly used as an industrial solvent. It is a clear non-flammable liquid with a sweet smell.
The bitumen used in asphalt and road construction should not have excess impurities. For this purpose, the bitumen is dissolved in the trichloroethylene material, the bitumen is dissolved in this material, but the impurity, like contains salt, carbon and minerals, will not be solved.
To determine the degree of purity of bitumen and asphaltic materials that are small or minerals we can use the standard solubility test using trichloroethylene is designated as ASTM D 2042.
Due to the extreme flammability of carbon disulfide, solubility in trichloroethylene, rather than solubility in carbon disulfide, is usually used in asphalt cement specifications.
Filter Flask, heavy-wall, with side tube, 250- or500-mL capacity
Rubber Tubing or Adapter, for holding the Gooch Crucible on the filter tube.
Oven, capable of maintaining a temperature of 110±5°C
In this method, the test substance was dissolved in tetrachlorethylene and passed through a flat glass fiber.
Gets The insoluble material is washed, dried and weighed, thus the amount of impurities is determined.
If the test substance is not lubricated, we should heat it up to the proper temperature, but the temperature should not be tested more than 111 degrees Celsius above the soft point of the material.
% Insoluble = C-A/B ×100
% Soluble = B-(C-A)/B ×100
A = mass of crucible and filter
B = mass of sample
C = mass of crucible, filter and insoluble material
