Alias naphtha, English name: naphtha, the main ingredients: 5 to 11 carbon atoms of alkanes, cycloalkanes or aromatics. It is a fraction of coal tar at 0 – 180 C. Its color is colorless and transparent, but it turns reddish brown in the air for a long time. Relative density is 0.78-0.97g/cm 3. Flash point is – 2 ℃, ignition temperature is 350℃, insoluble in water, soluble in most organic solvents. The content is about 0.45%-0.7% of the high temperature coal tar content.
Usage: Mainly used for extracting benzene, is the main raw material of benzene products, which is mainly used to replace crude benzene, can also be used for solvent oil, blending fuel oil.
Main ingredients: benzene, toluene, xylene. (Downstream manufacturers test triphenyl content, benzene hydrogenation industry test chlorine sulfur content, black cat triphenyl content is more than 80%, but chloride ion content is in)
