Dichloromethane is an organic substance with the molecular formula CH2Cl2, a colorless transparent liquid with an irritating odor similar to that of ether. Slightly soluble in water and soluble in ethanol and ether, it is a non-combustible low boiling solvent under usual conditions of use, and its vapor becomes highly concentrated in hot air before […]

Naphthalene refining rate is the ratio of the amount of naphthalene in the naphthalene refining product to the amount of naphthalene in the raw material, expressed as a percentage. It is one of the indicators to evaluate the naphthalene oil fraction processing and naphthalene refining process and operation level. In addition to naphthalene, technical naphthalene […]

One of the main tasks of tar distillation is to cut the naphthalene-containing fraction for further separation and refining. refining. In the process of tar distillation, according to the different fraction cutting process systems, the naphthalene enriched fractions are  Naphthalene oil fraction, naphthalene washed mixed fraction and phenol naphthalene washed triple mixed fraction, etc. Technical […]
