Will there be gas in the organic solvent? Why?

Some organic solvents are volatile and will produce a lot of gas after oscillation.

If it is not deflated, it may be that the air pressure in the separation funnel is too high and an explosion occurs. Organic solvents are highly volatile, flammable and explosive, and some of them can be volatilized into gas at room temperature, which can enter the human body through many ways and damage many organs.

Organic solvents refer to organic compounds that dissolve oil, wax, resin, rubber, dyes and other substances. The form of organic solvents in the production process is mostly liquid or vapor formed by liquid evaporation, such as gasoline and gasoline vapor. Benzene, benzene vapor. Carbon disulfide, carbon disulfide vapor, etc.
