Hoʻolauna | benzoyl chloride (CAS98-88-4) ʻike ʻia hoʻi he benzoyl chloride, benzoyl chloride, no ke ʻano o ka waikawa chloride. ʻO ka wai ʻaʻaʻa ʻole ke kala ʻole, ʻike ʻia i ka uahi ea. ʻO nā huahana ʻoihana me ka melemele māmā, me kahi ʻala hoʻonāukiuki ikaika. ʻO ka mahu ma ka mucosa maka, ka ʻili a me ka ʻōpū hanu he hopena hoʻoulu ikaika, ma ka hoʻoulu ʻana i ka mucosa maka a me ka waimaka. ʻO Benzoyl chloride kahi mea koʻikoʻi koʻikoʻi no ka hoʻomākaukau ʻana i nā kala, nā mea ʻala, nā peroxide organik, nā lāʻau lapaʻau a me nā resins. Ua hoʻohana pū ʻia i ke kiʻi a me ka hana ʻana i nā tannins artificial, a ua hoʻohana ʻia ma ke ʻano he kinoea hoʻoikaika i ke kaua kemika. ʻO ke kiʻi 1 ke kumu hoʻohālike o benzoyl chloride |
ʻano hoʻomākaukau | i loko o ke keʻena hana, hiki ke loaʻa ka benzoyl chloride ma ka distilling benzoic acid a me ka phosphorus pentachloride ma lalo o nā kūlana anhydrous. Hiki ke loaʻa ke ʻano hoʻomākaukau ʻoihana ma ka hoʻohana ʻana i ka thionyl chloride a me benzaldehyde chloride. |

Hoʻohana | ʻO benzoyl chloride kahi mea waena o ka herbicide oxazinone, a he mea waena hoʻi ia o ka insecticide benzenecpid, hydrazine inhibitor. Hoʻohana ʻia ka benzoyl chloride ma ke ʻano he mea maka no ka synthesis organik, nā mea pena a me nā lāʻau lapaʻau, a ma ke ʻano he mea hoʻomaka, dibenzoyl peroxide, tert-butyl peroxide, pesticide herbicide, a me nā mea ʻē aʻe. , Karphos) waena. He mea koʻikoʻi ka benzoylation a me ka reagent benzylation. Hoʻohana ʻia ka hapa nui o ka benzoyl chloride e hana i ka benzoyl peroxide, a ukali ʻia e ka hana ʻana o benzophenone, benzyl benzoate, benzyl cellulose a me benzamide a me nā mea waiwai nui ʻē aʻe, benzoyl peroxide no ka polymerization initiator o ka monomer plastic, polyester, epoxy, catalyst no ka resin acrylic. hana, coagulant pono'ī no ke aniani fiber material, crosslinking agent no silicone fluororubber, aila hoʻomaʻemaʻe, palaoa. bleaching, fiber decolorization, etc. Eia kekahi, hiki ke hoʻopili ʻia ka waikawa benzoic me benzoyl chloride e hana i ka benzoic anhydride. ʻO ka hoʻohana nui o ka benzoic anhydride ma ke ʻano he acylating agent, ma ke ʻano he ʻāpana o ka bleaching agent a me ka flux, a me ka hoʻomākaukau ʻana i ka benzoyl peroxide. hoʻohana ʻia e like me nā reagents analytical, hoʻohana ʻia i nā mea ʻala, synthesis organik |
hana hana | 1. Toluene hana maka mea toluene a me ka chlorine i loko o ka malamalama ma lalo o ke kūlana o ka pane, aoao kaulahao chlorination e hana α-trichlorotoluene, ka hope i loko o acidic medium hydrolysis e hana benzoyl chloride, a me ka hoʻokuʻu 'ana o ka hydrogen chloride kinoea (hana o ka wai absorption. o ke kinoea HCl). 2. ʻO ka waikawa benzoic a me ka hopena phosgene. Hoʻokomo ʻia ka waikawa benzoic i loko o ka ipuhao photochemical, wela a hoʻoheheʻe ʻia, a hoʻokomo ʻia ka phosgene ma 140-150 ℃. ʻO ke kinoea huelo hopena i loaʻa i ka hydrogen chloride a me ka phosgene unreacted, i mālama ʻia me ka alkali a i hoʻokuʻu ʻia, ʻo ka mahana ma ka hopena o ka hopena he -2-3 °c, a ua hoʻoheheʻe ʻia ka huahana ma lalo o ke kaomi hoʻemi ʻana ma hope o ka hana hoʻoneʻe kinoea. ʻO nā huahana ʻoihana he wai ʻākala melemele. Maʻemaʻe ≥ 98%. ʻO ka nui o ka hoʻohana ʻana i nā mea kanu: benzoic acid 920kg/t, phosgene 1100kg/t, dimethylformamide 3kg/t, wai alkali (30%)900kg/t. I kēia manawa, hoʻohana nui ʻia i ka ʻoihana o ka benzoic acid a me ka hoʻomākaukau ʻana i ka hopena benzylidene chloride. Hiki ke loaʻa ka Benzoyl chloride ma ka chlorination pololei o benzaldehyde. Nui nā ʻano hoʻomākaukau. (1) Hoʻomaʻamaʻa ʻia ka waikawa benzoic a hoʻoheheʻe ʻia e ke ʻano phosgene, a hoʻokomo ʻia ka phosgene ma 140 ~ 150 ℃, a hoʻokomo ʻia kahi nui o ka phosgene a hiki i ka hopena. Hoʻokomo ʻia ka phosgene e ka nitrogen, a hoʻopaʻa ʻia ke kinoea huelo a luku ʻia, loaʻa ka huahana hope ma ka distillation ma lalo o ke kaomi hoʻemi. (2) phosphorus trichloride method benzoic acid i hoʻoheheʻe ʻia i loko o toluene a me nā solvents ʻē aʻe, ua hoʻohui ʻia ka Phosphorus trichloride dropwise, a ua lawe ʻia ka hopena no kekahi mau hola ma hope o ka hāʻule ʻana, ua hoʻopau ʻia ka toluene, a laila ua hoʻopau ʻia ka huahana i hoʻopau ʻia. (3) trichloromethylbenzene ala e toluene aoao kaulahao chlorination, a laila hydrolysis huahana. |
