I use light oil (naphtha) in my production process. What are its main ingredients?

Physical and chemical properties Main ingredients: It is mainly the C4~C6 component of alkanes. Appearance and properties: Colorless or light yellow liquid. Boiling point(℃): 20～160 relative density (water=1): 0.78～0.97 Flash point(℃): -2 Ignition temperature (℃): 350 Explosion upper limit% (V/V): 8.7 Lower explosion limit%(V/V): 1.1 Solubility: Insoluble in water, soluble in most organic solvents. Main purpose: A variety of organic raw materials can be separated, such as gasoline, benzene, kerosene, asphalt, etc. health hazards: Naphtha vapor can cause eye and upper respiratory tract irritation symptoms. If the concentration is too high, it can cause dyspnea, cyanosis and other hypoxic symptoms within a few minutes. environmental hazards: It is harmful to the environment and can cause pollution to water bodies, soil and atmosphere. Fire and explosion hazard: This product is flammable and irritating. Hazardous properties: Its vapor and air can form an explosive mixture, which can cause combustion and explosion when exposed to open flames or high heat. Can react strongly with oxidizing agents. Its vapor is heavier than air and can spread to a considerable distance from a lower place. It will ignite and backfire when encountering a fire source.
