Physical and chemical properties of benzoyl chloride

Phenylacetyl chloride is a smoking liquid with no color to light yellow, and its physical properties exhibit this color under visible light. Its relative density is slightly higher than that of water, about 1.17, which means that it will sink to the bottom of the water in terms of density. The boiling point of this compound is 210.0 ℃, indicating that it is liquid at room temperature. Its molecular formula is C8H7ClO, with a molecular weight of 154.60 g/mol, indicating a complex molecular structure containing carbon, hydrogen, and oxygen elements.

In terms of vapor pressure, the saturated vapor pressure of benzoyl chloride at 48 ℃ is 0.13 kPa, indicating that it releases a moderate amount of vapor at room temperature. It is worth noting that its flash point is as high as 102 ℃, which means that it will not easily ignite below this temperature. However, the chemical properties of benzoyl chloride are relatively active, and it is flammable when exposed to open flames or high temperatures. When decomposed, it releases toxic and highly corrosive smoke, which requires extra caution in safe operation.

In addition, benzoyl chloride has strong chemical activity and can trigger chemical reactions when in contact with strong oxidants. Its corrosiveness is not only reflected in its destructive effect on certain metals, but also means avoiding direct contact with metal surfaces during storage and handling to prevent potential chemical reactions and damage.
