Soluble in ethyl ether, chloroform, benzene and carbon disulfide.
Under water, ammonia or ethanol gradually decompose, generating benzoic acid, benzamide or ethyl benzoatebe and hydrogen chloride.
Application:
Benzoyl chloride used for organic synthesis, dyes and pharmaceutical raw materials, manufacturing initiator benzoyl peroxide, benzoic acid tert-butyl peroxide, pesticides herbicides and so on.
In pesticides, is a new inducible pesticide , is isoxathion intermediates.
Benzoyl chloride are important benzoylation and benzylation reagent. Most of Benzoyl chloride is used for the production of benzoyl peroxide, and for the production of benzophenone, benzyl benzoate, benzyl cellulose and benzamide and other important chemical raw material . Benzoyl peroxide is used for the polymerization initiator of the plastic monomers , catalyst of producing polyester, epoxy, acrylicresin , self-curing agent of the glass fiber materials , the crosslinking agent of the silicon fluorine rubber , oil refining , Bleaching flour , fiber bleaching, and so on.
Additional, benzoic acid and benzoyl chloride can also produce acid anhydride, acid anhydride is the main purpose for acylation agent, also can be used as bleaching agent and a flux component, but also for the preparation of benzoyl peroxide .
