| Isingeniso | i-benzoyl chloride (CAS98-88-4) eyaziwa nangokuthi i-benzoyl chloride, i-benzoyl chloride, eyingxenye ye-acid chloride. Uketshezi olucwengekile olungenambala oluvutha umlilo, ukuchayeka entuthuni yomoya. Imikhiqizo yezimboni ephuzi ngokukhanyayo, enephunga elinamandla elicasulayo. Umhwamuko ku-eye mucosa, isikhumba kanye nomgudu wokuphefumula unomphumela onamandla ovuselelayo, ngokuvuselela i-eye mucosa nokukhala. I-Benzoyl chloride iyisiphakathi esibalulekile sokulungiswa kodayi, amakha, ama-peroxides aphilayo, imithi kanye nama-resin. Ibuye isetshenziselwe ukuthwebula izithombe kanye nokukhiqizwa kwama-tannins okwenziwa, futhi iye yasetshenziswa njengegesi evuselelayo ezimpini zamakhemikhali. Umfanekiso 1 uyifomula yesakhiwo se-benzoyl chloride |
| indlela yokulungiselela | elabhorethri, i-benzoyl chloride ingatholwa ngokukhipha i-benzoic acid ne-phosphorus pentachloride ngaphansi kwezimo ezingenamanzi. Indlela yokulungiselela izimboni ingatholakala ngokusebenzisa i-thionyl chloride ne-benzaldehyde chloride. |
| isigaba sobungozi | isigaba esiyingozi se-benzoyl chloride: 8 |
| Sebenzisa | I-benzoyl chloride iyingxenye emaphakathi ye-oxazinone yokubulala ukhula, futhi iyisibulala-zinambuzane se-benzenecapid, i-hydrazine inhibitor. I-benzoyl chloride isetshenziswa njengezinto ezingavuthiwe zokwenziwa kwe-organic, odayi nemithi, futhi njengesiqalisi, i-benzoyl peroxide, i-tert-butyl peroxide, isibulala-zinambuzane, njll. Ngokuphathelene nezibulala-zinambuzane, uhlobo olusha lwesibulala-zinambuzane esingashiwongo isoxazole thiophos (isoxathon , Karphos) phakathi. Kubuye kube i-benzoylation ebalulekile kanye ne-benzylation reagent. Iningi le-benzoyl chloride lisetshenziselwa ukukhiqiza i-benzoyl peroxide, kulandele ukukhiqizwa kwe-benzophenone, i-benzyl benzoate, i-benzyl cellulose ne-benzamide nezinye izinto ezibalulekile zamakhemikhali, i-benzoyl peroxide ye-polymerization initiator ye-plastiki monomer, i-polyester, i-epoxy, i-catalyst ye-acrylic resin. ukukhiqizwa, i-self-coagulant ye-glass fiber material, i-crosslinking agent ye-silicone fluororubber, uwoyela ukucwenga, ukwenza ufulawa kube mhlophe, i-fiber decolorization, njll. Ngaphezu kwalokho, i-benzoic acid ingasabela nge-benzoyl chloride ukukhiqiza i-benzoic anhydride. Ukusetshenziswa okuyinhloko kwe-benzoic anhydride kufana ne-acylating agent, njengengxenye ye-bleaching agent kanye ne-flux, kanye nasekulungiseleleni i-benzoyl peroxide. esetshenziswa njengama-reagents okuhlaziya, abuye asetshenziswe izinongo, ukwakheka kwe-organic |
| indlela yokukhiqiza | 1. Indlela ye-toluene ngezinto zokusetshenziswa ze-toluene ne-chlorine ekukhanyeni ngaphansi kwesimo sokusabela, ukuxutshwa kweketango eliseceleni ukuze kukhiqizwe i-α-trichlorotoluene, le yokugcina ku-acidic medium hydrolysis ukukhiqiza i-benzoyl chloride, kanye nokukhululwa kwegesi ye-hydrogen chloride (ukukhiqizwa kokumuncwa kwamanzi. igesi ye-HCl). 2. I-Benzoic acid kanye ne-phosgene reaction. I-benzoic acid ifakwa ebhodweni le-photochemical, ifudunyezwe futhi incibilike, bese i-phosgene yethulwa ku-140-150 ℃. Igesi yomsila wokusabela iqukethe i-hydrogen chloride ne-phosgene engaphenduliwe, ephathwa nge-alkali futhi ifakwe umoya, izinga lokushisa ekupheleni kokusabela laliyi--2-3 °c, futhi umkhiqizo wahlungwa ngaphansi kwengcindezi encishisiwe ngemva kokusebenza kokukhipha igesi. Imikhiqizo yezimboni iwuketshezi olukhanyayo oluphuzi. Ubumsulwa ≥ 98%. Isilinganiso sokusetshenziswa kwempahla eluhlaza: i-benzoic acid 920kg/t, i-phosgene 1100kg/t, i-dimethylformamide 3kg/t, i-alkali ewuketshezi (30%)900kg/t. Manje isetshenziswa kabanzi embonini ye-benzoic acid kanye ne-benzyldene chloride reaction reaction. I-Benzoyl chloride ingatholakala futhi nge-chlorination eqondile ye-benzaldehyde. Kunezindlela eziningana zokulungiselela. (1) I-benzoic acid iyashiswa futhi incibilike ngendlela ye-phosgene, futhi i-phosgene yethulwa ku-140 ~ 150 ℃, futhi inani elithile le-phosgene lethulwa ukuze lifinyelele iphuzu lokugcina. I-phosgene iqhutshwa yi-nitrogen, futhi igesi yomsila iyamuncwa futhi ibhujiswe, umkhiqizo wokugcina watholwa ngokufakwa kwe-distillation ngaphansi kwengcindezi encishisiwe. (2) indlela ye-phosphorus trichloride ye-benzoic acid encibilikisiwe ku-toluene nakwezinye izincibilikisi, i-Phosphorus trichloride yengezwa ngokudonsela phansi, futhi ukusabela kwenziwa amahora amaningana ngemva kokuwa, i-toluene yachithwa, bese umkhiqizo ophelile wachithwa. (3) indlela ye-trichloromethylbenzene ye-toluene side chain chlorination, bese kuba umkhiqizo we-hydrolysis. |
