Intshayelelo	i-benzoyl chloride (CAS98-88-4) ekwabizwa ngokuba yi-benzoyl chloride, i-benzoyl chloride, yohlobo lwe-acid chloride. Ulwelo olucocekileyo olungenambala olucacileyo olunokutsha, ukuchanabeka kumsi womoya. Iimveliso zemizi-mveliso ezinombala ophuzi okhanyayo, kunye nephunga elinamandla elicaphukisayo. Umphunga kwi-eye mucosa, ulusu kunye nomgudu wokuphefumla unefuthe elinamandla elivuselelayo, ngokuvuselela i-mucosa yamehlo kunye nokukrazula. I-Benzoyl chloride yinto ebalulekileyo ephakathi ukulungiselela iidayi, iziqholo, iiperoxides ze-organic, amayeza kunye ne-resins. Ikwasetyenziswa ekufotweni nasekuveliseni iitannins ezenziweyo, kwaye isetyenziswe njengerhasi evuselelayo kwimfazwe yemichiza. Umzobo 1 yifomula yesakhiwo se-benzoyl chloride
indlela yokulungiselela	elabhoratri, benzoyl chloride inokufunyanwa distilling benzoic acid kunye phosphorus pentachloride phantsi kweemeko anhydrous. Indlela yokulungiselela ishishini inokufumaneka ngokusebenzisa i-thionyl chloride kunye ne-benzaldehyde chloride.
udidi lwengozi	udidi lwengozi ye-benzoyl chloride: 8
Sebenzisa	I-benzoyl chloride yindawo ephakathi kwi-oxazinone ye-herbicide, kwaye ikwayindawo ephakathi kwi-insecticide benzenecapid, ihydrazine inhibitor. i-benzoyl chloride isetyenziswe njengezinto eziluhlaza kwi-organic synthesis, idayi kunye namayeza, kwaye njenge-initiator, dibenzoyl peroxide, i-tert-butyl peroxide, i-pesticide herbicide, njl. Ngokwemiqathango ye-pesticides, luhlobo olutsha lwe-insecticide inducible isoxazole thiophos (isoxathon). , Karphos) abaphakathi. Kwakhona i-benzoylation ebalulekileyo kunye ne-benzylation reagent. Uninzi lwe-benzoyl chloride isetyenziselwa ukuvelisa i-benzoyl peroxide, ilandelwa kukuveliswa kwe-benzophenone, i-benzyl benzoate, i-benzyl cellulose kunye ne-benzamide kunye nezinye izinto ezibalulekileyo zemichiza ekrwada, i-benzoyl peroxide ye-polymerization initiator ye-plastiki monomer, i-polyester, i-epoxy, i-catalyst ye-acrylic resin. imveliso, i-self-coagulant ye-glass fiber material, i-agent edibeneyo ye-silicone fluororubber, ioli ukucokisa, ukuxutywa komgubo, i-fiber decolorization, njl njl. Ukongeza, i-benzoic acid inokuphendulwa kunye ne-benzoyl chloride ukuvelisa i-benzoic anhydride. Ukusetyenziswa okuphambili kwe-benzoic anhydride njenge-acylating agent, njengenxalenye ye-bleaching agent kunye ne-flux, kunye nokulungiswa kwe-benzoyl peroxide. isetyenziswe njengee-reagents zohlalutyo, iphinda isetyenziswe kwiziqholo, i-organic synthesis
indlela yokuvelisa	1. Indlela ye-toluene ekrwada izinto ze-toluene kunye neklorini ekukhanyeni phantsi kwemeko yokusabela, i-side chain chlorination ukuvelisa i-α-trichlorotoluene, le yokugqibela kwi-acidic medium hydrolysis ukuvelisa i-benzoyl chloride, kunye nokukhululwa kwegesi ye-hydrogen chloride (ukuveliswa kokufunxa kwamanzi. yegesi yeHCl). 2. I-Benzoic acid kunye ne-phosgene reaction. I-asidi ye-benzoic ifakwe kwi-photochemical pot, ifudunyezwe kwaye inyibilike, kwaye i-phosgene ifakwe kwi-140-150 ℃. Irhasi yomsila wokusabela iqulethe i-hydrogen chloride kunye ne-phosgene engaphendulwanga, ephathwa nge-alkali kunye ne-venting, ubushushu ekupheleni kokusabela kwaba ngu-2-3 °c, kwaye imveliso yachithwa phantsi koxinzelelo oluncitshisiweyo emva kokusebenza kokususwa kwegesi. Iimveliso zamashishini zilulwelo olutyheli olucacileyo. Ubunyulu ≥ 98%. I-quota yokusetyenziswa kwezinto eziluhlaza: i-benzoic acid 920kg / t, i-phosgene 1100kg / t, i-dimethylformamide 3kg / t, i-alkali yolwelo (30%) 900kg / t. Ngoku isetyenziswa ngokubanzi kwishishini le-benzoic acid kunye ne-benzyldene chloride reaction reaction. I-Benzoyl chloride inokufumaneka kwakhona nge-chlorination ngqo ye-benzaldehyde. Kukho iindlela ezininzi zokulungiselela. (1) I-asidi ye-benzoic ishushu kwaye iyancibilika ngendlela ye-phosgene, kwaye i-phosgene ifakwe kwi-140 ~ 150 ℃, kwaye inani elithile le-phosgene liyaziswa ukufikelela ekupheleni. I-phosgene iqhutywe yi-nitrogen, kwaye i-gas yomsila ifunnwe kwaye itshatyalaliswe, imveliso yokugqibela yafunyanwa ngokuxutywa kwe-distillation phantsi koxinzelelo oluncitshisiweyo. 2 (3) indlela ye-trichloromethylbenzene kwi-toluene side chain chlorination, kunye nemveliso ye-hydrolysis.
