Mawu Oyamba	benzoyl chloride (CAS98-88-4) yomwe imadziwikanso kuti benzoyl chloride, benzoyl chloride, ya mtundu wa asidi chloride. Madzi oyera osawoneka bwino oyaka, kukhudzana ndi utsi wa mpweya. Zogulitsa zamafakitale zokhala ndi chikasu chowala, zokhala ndi fungo loyipa lowopsa. Nthunzi pa diso mucosa, khungu ndi kupuma thirakiti ali amphamvu zolimbikitsa kwenikweni, ndi zolimbikitsa diso mucosa ndi misozi. Benzoyl kolorayidi ndi yofunika yapakatikati yokonza utoto, zonunkhira, organic peroxides, mankhwala ndi utomoni. Amagwiritsidwanso ntchito pojambula ndi kupanga ma tannins ochita kupanga, ndipo akhala akugwiritsidwa ntchito ngati mpweya wotsitsimutsa pankhondo yamankhwala. Chithunzi 1 ndi mawonekedwe a benzoyl chloride
njira yokonzekera	mu labotale, benzoyl kolorayidi angapezeke mwa distilling asidi benzoic ndi phosphorous pentachloride pansi anhydrous mikhalidwe. Njira yokonzekera mafakitale imatha kupezeka pogwiritsa ntchito thionyl chloride ndi benzaldehyde chloride.
gulu langozi	Gulu lowopsa la benzoyl chloride: 8
Gwiritsani ntchito	benzoyl chloride ndi wapakatikati wa herbicide oxazinone, komanso ndi wapakatikati mwa mankhwala ophera tizilombo benzenecapid, hydrazine inhibitor. benzoyl kolorayidi ntchito ngati zopangira organic kaphatikizidwe, utoto ndi mankhwala, ndipo monga initiator, dibenzoyl peroxide, tert-butyl peroxide, mankhwala herbicide, etc. Pankhani ya mankhwala, ndi mtundu watsopano wa inducible insecticide isoxazole thiophos (isoxathon). , Karphos) pakati. Ndiwofunikanso benzoylation ndi benzylation reagent. Ambiri a benzoyl kolorayidi ntchito kupanga benzoyl peroxide, kenako kupanga benzophenone, benzyl benzoate, benzyl mapadi ndi benzamide ndi zinthu zina zofunika mankhwala zopangira, benzoyl peroxide kwa polymerization woyambitsa wa pulasitiki monoma, poliyesitala, epoxy, chothandizira kuti akiliriki utomoni. kupanga, self-coagulant kwa galasi CHIKWANGWANI chuma, crosslinking wothandizira silikoni fluororubber, mafuta kuyenga, kuthira ufa ufa, ulusi decolorization, etc. Kuphatikiza apo, asidi benzoic amatha kuchitapo kanthu ndi benzoyl chloride kupanga benzoic anhydride. Ntchito yaikulu ya benzoic anhydride ndi monga acylating wothandizira, monga chigawo cha bleaching wothandizira ndi flux, komanso pokonza benzoyl peroxide. amagwiritsidwa ntchito ngati ma analytical reagents, omwe amagwiritsidwanso ntchito mu zonunkhira, organic synthesis
njira yopanga	1. Toluene njira zopangira toluene ndi klorini mu kuwala pansi mmene zimachitikira, mbali unyolo chlorination kubala α-trichlorotoluene, yotsirizira mu acidic sing'anga hydrolysis kupanga benzoyl kolorayidi, ndi kutulutsidwa kwa hydrogen kolorayidi mpweya (kupanga mayamwidwe madzi). HCl gasi). 2. Benzoic acid ndi phosgene reaction. Benzoic acid imayikidwa mumphika wa photochemical, kutenthedwa ndi kusungunuka, ndipo phosgene imayambitsidwa pa 140-150 ℃. Zomwe mchira wa mpweya uli ndi hydrogen chloride ndi phosgene yosasinthika, yomwe imathandizidwa ndi alkali ndi kutulutsa mpweya, kutentha kumapeto kwa zomwe zinali -2-3 ° C, ndipo mankhwalawa anali osungunuka pansi pa kupanikizika kwafupipafupi pambuyo pa ntchito yochotsa mpweya. Zogulitsa zamafakitale ndi zakumwa zachikasu zowonekera. Kuyera ≥ 98%. Kuchuluka kwa zinthu zopangira: benzoic acid 920kg/t, phosgene 1100kg/t, dimethylformamide 3kg/t, alkali yamadzi (30%) 900kg/t. Tsopano ambiri ntchito mu makampani a asidi benzoic ndi benzyldene mankhwala enaake anachita kukonzekera. Benzoyl kolorayidi amathanso kupezedwa ndi benzaldehyde mwachindunji. Pali njira zingapo zokonzekera. (1) Benzoic acid imatenthedwa ndikusungunuka ndi njira ya phosgene, ndipo phosgene imayambitsidwa pa 140 ~ 150 ℃, ndipo phosgene yochuluka imayambitsidwa kuti ifike kumapeto. Phosgene imayendetsedwa ndi nayitrogeni, ndipo mpweya wa mchira umatengedwa ndikuwonongeka, chomalizacho chinapezedwa ndi distillation pansi pa kupsinjika kwapakati. (2) phosphorous trichloride njira benzoic asidi kusungunuka mu toluene ndi zosungunulira zina, Phosphorus trichloride anawonjezera dropwise, ndi zimene zinachitika kwa maola angapo pambuyo dontho, toluene anali distilled, ndiyeno yomalizidwa anali distilled. (3) trichloromethylbenzene njira toluene mbali unyolo chlorination, ndiyeno hydrolysis mankhwala.
