Nhanganyaya	benzoyl chloride (CAS98-88-4) inozivikanwawo se benzoyl chloride, benzoyl chloride, yerudzi rweasidhi chloride. Mvura yakachena isina ruvara inopenya inopfuta, kuratidzwa nehutsi hwemhepo. Zvigadzirwa zveindasitiri zvine yellow yellow, zvine kunhuhwirira kwakasimba kunogumbura. Utsi paziso mucosa, ganda uye kufema turakiti ane simba stimulating mugumisiro, nokukurudzira ziso mucosa uye kubvarura. Benzoyl chloride yakakosha yepakati pakugadzirwa kwedhayi, zvinonhuwira, organic peroxides, mishonga uye resins. Yakashandiswawo mukutora mifananidzo uye kugadzira matannins ekugadzira, uye yakashandiswa segasi rinokurudzira muhondo yemakemikari. Mufananidzo 1 ndiyo yemaitiro ekugadzirisa benzoyl chloride
nzira yekugadzirira	murabhoritari, benzoyl chloride inogona kuwanikwa kuburikidza nekuita distilling benzoic acid uye phosphorus pentachloride pasi peanhydrous conditions. Nzira yekugadzirira maindasitiri inogona kuwanikwa nekushandisa thionyl chloride uye benzaldehyde chloride.
njodzi chikamu	chikamu chengozi ye benzoyl chloride: 8
Shandisa	benzoyl chloride inhengo yepakati yemushonga wesora oxazinone, uye iri pakati pemushonga wezvipembenene benzenecapid, hydrazine inhibitor. benzoyl chloride inoshandiswa seyakagadzirwa organic synthesis, dhayi nemishonga, uye sekutanga, dibenzoyl peroxide, tert-butyl peroxide, pesticide herbicide, etc. Panyaya yemishonga yezvipembenene, rudzi rutsva rwe inducible insecticide isoxazole thiophos (isoxathon). , Karphos) pakati. Iyo zvakare yakakosha benzoylation uye benzylation reagent. Yakawanda yebenzoyl chloride inoshandiswa kugadzira benzoyl peroxide, ichiteverwa nekugadzirwa kwebenzophenone, benzyl benzoate, benzyl cellulose uye benzamide uye mamwe makemikari akakosha ezvigadzirwa, benzoyl peroxide yepolymerization initiator yeplastiki monomer, polyester, epoxy, catalyst ye acrylic resin. kugadzirwa, self-coagulant yegirazi fiber zvinhu, crosslinking agent yesilicone fluororubber, mafuta kunatsa, kucheneswa kwehupfu, fibre decolorization, etc. Pamusoro pezvo, benzoic acid inogona kubatwa nebenzoyl chloride kugadzira benzoic anhydride. Kunyanya kushandiswa kwebenzoic anhydride seacylating agent, sechikamu che bleaching agent uye flux, uyewo mukugadzirira benzoyl peroxide. inoshandiswa seanalytical reagents, inoshandiswawo muzvinonhuwira, organic synthesis
kugadzira nzira	1. Toluene nzira yezvakagadzirwa toluene uye chlorine muchiedza pasi pemamiriro ekuita, side chain chlorination kuti ibudise α-trichlorotoluene, iyo yekupedzisira mu acidic medium hydrolysis kugadzira benzoyl chloride, uye kubudiswa kwehydrogen chloride gasi (kugadzirwa kwemvura. yeHCl gasi). 2. Benzoic acid uye phosgene reaction. Iyo benzoic acid inoiswa mupoto yephotochemical, inopisa nekunyungudutswa, uye phosgene inounzwa pa140-150 ℃. Mhedzisiro yemuswe gasi ine hydrogen chloride uye isina kubatwa phosgene, iyo inobatwa nealkali uye inofefetera, tembiricha pakupera kwekuita yaive -2-3 ° c, uye chigadzirwa chakanyungudutswa pasi pekumanikidzwa kwakaderedzwa mushure mekubvisa gasi kushanda. Zvigadzirwa zvemaindasitiri zvinwiwa zveyero zvinoonekera. Kuchena ≥ 98%. Raw material use quota: benzoic acid 920kg/t, phosgene 1100kg/t, dimethylformamide 3kg/t, liquid alkali (30%)900kg/t. Ikozvino inoshandiswa zvakanyanya muindasitiri ye benzoic acid uye benzyldene chloride reaction gadziriro. Benzoyl chloride inogonawo kuwanikwa nekunatswa chlorination ye benzaldehyde. Kune nzira dzakawanda dzekugadzirira. (1) Iyo benzoic asidhi inopisa uye yakanyungudutswa nenzira yephosgene, uye phosgene inotangwa pa140 ~ 150 ℃, uye imwe huwandu hwephosgene hunounzwa kusvika kumagumo. Iyo phosgene inofambiswa ne nitrogen, uye gasi remuswe rinotorwa uye rinoparadzwa, chigadzirwa chekupedzisira chakawanikwa ne distillation pasi pekumanikidzwa kwakaderedzwa. (2) phosphorus trichloride nzira ye benzoic acid yakanyungudutswa mu toluene nezvimwe zvinonyungudutsa, Phosphorus trichloride yakawedzerwa inodonha, uye maitiro akaitwa kwemaawa akati wandei mushure mekudonha, toluene yakanyungudutswa, uyezve chigadzirwa chakapedzwa chakabviswa. (3) trichloromethylbenzene nzira kuti toluene divi cheni chlorination, uye ipapo hydrolysis chigadzirwa.
