Naphtha with high silicon content
Thread Content
Is there any known use for naphtha with up to 3000 ppm of silicon? Seeking advice from experts everywhere
Have you mixed silicone oil into the naphtha?

Therefore, it is either silicone oil or an antifoaming agent containing silicon. It certainly isn’t inorganic silicon, because based on silica, its concentration must be above 7000 ppm, almost 1%; if it cannot dissolve, it will precipitate or settle out. This naphtha is simply distilled to leave behind the last 10%, and the form of silicon is determined, either using infrared spectroscopy or chromatography-mass spectrometry. This allows one to determine the morphology and composition of silicon. It is estimated that silicon-containing organic compounds are dissolved and added to other materials as defoamers or antistatic agents, etc.
