Benzoyl chloride is an organic compound used as dye intermediates, initiators, ultraviolet absorbers, rubber and plastic additives, medicines, etc.
What is Benzoyl Chloride?
Benzoyl chloride is an important intermediate for preparing dyes, perfumes, organic peroxides, drugs, and resins. Benzoyl chloride is also used in photography, in the production of artificial tannins, and as an irritant gas in chemical warfare.
As a raw material for organic synthesis, dyes and medicines, benzoyl chloride is used to prepare initiators such as dibenzoyl peroxide, tert-butyl peroxybenzoate, pesticides, and herbicides.
As far as pesticides are concerned, it is a new type of inducer and an intermediate of isotonic. Benzoyl chloride is an important benzoylation and benzylation reagent.
Most benzoyl chloride is used to produce benzoyl peroxide, followed by necessary chemical raw materials such as benzophenone, benzyl benzoate, benzyl cellulose, and benzamide.
Benzoyl peroxide is used as a polymerization initiator for plastic monomers, a catalyst for the production of polyester, epoxy and acrylic resins, a self-setting agent for glass fiber materials, a crosslinking agent for silicone rubber, oil refining, flour bleaching, fiber decolorization, etc..
Benzoic acid can react with benzoyl chloride to produce phthalic anhydride, which is mainly used as a component of acylating agents, bleaches and fluxes, and is also used to prepare benzoyl peroxide. Benzoyl chloride is an important intermediate for preparing dyes, fragrances, organic peroxides, medicines and resins.
Application of Benzoyl Chloride
Benzoyl chloride is used as a raw material for the preparation of organic peroxides, pesticides, shilling dyes, benzotriazole ultraviolet absorbers, rubber antioxidants, and medicines. Benzoyl chloride is an important acylating agent and can be used to identify phenols, alcohols, amines, etc.
1. Benzoyl Peroxide
It is mainly used as an initiator for the polymerization of acrylic series resins, vinyl acetate resins, MMA resins, or a curing catalyst for polyester resin molding. It is also used as a bleaching agent for oil esters, waxes, and flour, as a desiccant for unsaturated oils, and as a fiber decolorizer.
2. Tert-Butyl Perbenzoate (TPB)
From the condensation of benzoyl chloride and tert-butyl peroxide. It is mainly used as a curing initiator for thermoforming of unsaturated polyester and polymerization catalyst for resin.
3. 2,2′-dibenzamidodiphenyl disulfide
By bis (o-aminophenyl) disulfide and benzoyl chloride reaction derived. It is mainly used as a peptizer for natural rubber and diene synthetic rubber.
4. p, p’-dibenzoylquinone dioxime
From the reaction of p-quinone oxime and benzoyl chloride. It is mainly used as a vulcanizing agent for butyl rubber, natural rubber and styrene-butadiene rubber, and has good anti-scorch performance. It is especially suitable for butyl rubber as inner tube, water tire, vulcanizing bladder and electric wire.
5. Dibenzothiamide
It is derived from the reaction of vitamin B1 with benzoyl chloride in sodium hydroxide solution. Used as a fortifier for noodles, tofu, and other foods.
6. Benzoic acid peroxide
It is obtained by synthesizing benzoyl peroxide from benzoyl chloride and oxidizing it with hydrogen peroxide. Benzoic acid peroxide is a strong oxidant, and ethyl perbenzoic acid acetate synthesized with ethylene is used for unsaturated compound analysis and determination of double bond numbers. Tert-butyl peroxy benzoate is used as silicone rubber and high-temperature vulcanized products.
7. Hippuric Acid
Synthesize sodium benzylaminoacetate from benzoyl chloride and amino acetic acid in sodium hydroxide solution, and then acidify it with hydrochloric acid. It is mainly used as an intermediate for dispersing fluorescent yellow FFL and synthesizing drugs.
8. 7-Hydroxyflavone
From 2,4-dihydroxy acetophenone and benzoyl chloride benzoylation derived after transformation. Used as an intermediate of flavonoid selective coronary vasodilators.
9. 2-Amino-5-chlorobenzophenone
It is derived from the catalytic reaction of p-chloroaniline and benzoyl chloride. It is a pharmaceutical intermediate, which is used in the production of diazepam drugs, diazepam, diazepam, nitrazepam, alprazolam, clonazepam, etc.
10. 2,5-dichlorobenzoic acid
By benzoyl chloride by chlorination, hydrolysis is derived. It is used in the synthesis of herbicides Tou Kewei and Di Cao Ping.
11. 2,5-Dichloro-p-phenylenediamine
After condensation of 2,5-dichloroaniline and benzoyl chloride. N-benzoyl-2,5-dichloro-4-nitroaniline is obtained by nitration, and then acid hydrolysis generates 2,5-dichloro-4-nitroaniline, which is obtained by reduction. It is used in the synthesis of azo dye CromophtalYellow6G, and can also be used as a raw material for polyurethane synthesis.
12. Benzophenone
It is derived from the condensation of benzene and benzoyl chloride under the catalysis of aluminum trichloride. Benzophenone is an intermediate of ultraviolet absorbers, organic pigments, medicines, spices, and insecticides. Benzophenone can be used as a heat carrier and calibration thermometer.
