Benzoyl chloride

Product introduction:

Benzoyl chloride, also known as benzoyl chloride and benzoyl chloride, belongs to a kind of acyl chloride. Steam has a strong stimulating effect on eye mucosa, skin and respiratory tract. It can induce tears by stimulating eye mucosa. The melting point of benzoyl chloride: - 1.0 ℃, boiling point 197.2 ℃, relative density 1.212 (20 ℃), flash point 72 ℃, refractive index (N20) 1.554. It decomposes gradually with water, ammonia or ethanol to form benzoic acid, benzamide or ethyl benzoate and hydrogen chloride. In the laboratory, it can be obtained by distillation of benzoic acid and phosphorus pentachloride under anhydrous conditions. The industrial preparation method can be obtained by using sulfoxide chloride and benzaldehyde chloride. Benzoyl chloride is an important intermediate for the preparation of dyes, spices, organic peroxides, drugs and resins. It is also used in photography and the production of artificial tannins. It has been used as an irritant gas in chemical warfare.

CAS：98-88-4

Molecular formula: C₇H₅ClO

Molecular weight: 140.57

Structural type:

Appearance: Colorless, transparent and flammable liquid, which emits smoke when exposed to air. It has a special pungent odor. The steam stimulates the ocular mucosa and causes tears. Soluble in ether, chloroform, benzene and carbon disulfide.

Product use：

Benzoyl chloride is used as raw materials for organic synthesis, dyes and medicine, and in the manufacture of initiator benzoyl peroxide, tert butyl benzoate peroxide, pesticides and herbicides.

1. In terms of pesticides, it is a new induced pesticide, which is an intermediate of isoxation (karphos).

2. Benzoyl chloride is an important benzoylation and benzylation reagent. Most benzoyl chloride is used to produce benzoyl peroxide, followed by important chemical raw materials such as benzophenone, benzyl benzoate, benzylcellulose and benzamide.
