It is a light oil that is processed from crude oil or other raw materials and used as a chemical raw material. It is mainly used as a chemical raw material. There are various distillation ranges for different purposes. China stipulates that the distillation range is about 220°C for the initial boiling point. When used as the cracking raw material for the production of ethylene, the 70°C~145°C fraction is used as light naphtha; when the purpose is to produce aromatic hydrocarbons or high-octane gasoline, the 70°C~180°C fraction is used to weigh the naphtha; When used as a solvent, it is called solvent naphtha; the aromatic solvent from coal tar is also called naphtha or solvent naphtha.
